industrial diesel oil fired steam boiler for sale

Factors affecting boiler gas consumption SZS20 tons of gas vapors which gas consumption is influenced by three factors: 1. Calorific value of the fuel; 2. Boiler thermal efficiency; 3. Operating level fireman. So, if you want to consume as little fuel boiler over a period of time, there are several options: 1. Select efficiency gas furnace. A gas boiler type on the market a lot, have a variety, the price is different. Thermal efficiency between 85% to 95%, the heat efficiency is different from different manufacturers. Small boiler factory price is relatively low, but poor results. A price is true, so when the time to buy, do not look cheap, money is to buy a truly efficient boilers in the price. 2, select high calorific value gas. Different heating values ​​of different fuels, different fuel heating value different origin. Just like oil, it is oil, but at a different price, per kilogram a few kilometers of oil is different. Of course, high calorific value, the price is relatively high. At the time of purchase, a good trade-off affecting the relationship between the price of both. 3, find an experienced operator. Regardless of the industry, when recruiting is like looking for the same experience, because experience is a treasure, you can do more things for the enterprise to save a lot of energy. Boiler workers, too, they save more money than those without experience. An experienced operator on a gas industrial diesel fired steam boiler for sale can save 10 tons in addition to the cost of about 100,000 yuan, the user is also very worried about another problem: 10 tons of natural gas steam boilers. Specific cost depends on the manufacturing process, brand, product quality and other manufacturers.

National Day holiday just ended, Shenyang Environmental Protection Bureau threw himself into the urban environment construction. Before the onset of winter, the Shenyang municipal government will strictly control the air pollution problem. It is reported that Shenyang Environmental Protection Bureau issued out since November 1, Shenyang will strictly enforce the standards of air pollutants emission limits in particular, all the environmental standards of heating enterprises will be cleared out of the heating market.

Shenyang Environmental Protection Bureau issued "on the thermal power industry, coal-fired boilers execution of air pollutants in particular emission limits of the notice" in the next year (the "Notice") requires: Thermal power within the gamut of Shenyang, iron and steel, petrochemical industry and fuel emissions of air pollutants in coal boiler project "thirteen five" period should implement special emission limit standards.

Shenyang is also a good environmental citizen blue sky, Shenyang City this winter and will continue to adhere to "turn point furnace, load shifting blocked arteries," the implementation of standards. After heating units gradually open blocked arteries, Municipal Environmental Protection Bureau will strengthen the routine inspection of law enforcement, and pay close attention to on-line monitoring data 474 coal-fired boilers, boiler emissions of non-compliance immediately ordered to carry out rectification, and severely dealt with strictly waste-water treatment, ultra row of such acts. At the same time, the Shenyang municipal government will also heating units regularly conduct random sampling of coal quality.

It is understood, Shenyang open blocked arteries in succession since October 26 from heating. To ensure that excessive heat stable and safe operation standards, Shenyang will be fully commissioning of heating facilities, to solve problems in a timely manner to ensure the November 1 time blocked arteries heating, the temperature reaches above 18 ℃. After the blocked arteries, Shenyang will strictly implement the winter heating emergency plans to complete the repair within 6 hours general accident, complete repairs within 24 hours more accidents.

Shenyang Environmental Protection Bureau official says, the environmental protection department will be heating business day on-line monitoring, and strictly control their emissions of air pollutants. Over the years, Shenyang has been doing the heating business "remove small and large," the relevant measures, so that some can not afford to increase environmental protection facilities of small companies to large companies merge powerful, let Shenyang municipal heating more environmentally friendly. Strict implementation of the special emission limits of air pollutants standards, both national policy, but also the heating of corporate responsibility, companies must increase investment in environmental protection to ensure the discharge standards.

It is understood that this year, the Shenyang municipal heating will continue to increase the proportion of clean energy, clean coal existing store 230,000 tons, an increase of 30,000 tons last year. Shenyang City, natural gas and other clean energy heating an area of ​​150 million square meters, clean heating the proportion reached 45%, up 6% over last year. Reduction of 1 million tons of total coal year, 5000 tons of coal-fired boilers to complete denitrification, the city starting from November 1 particularly strict implementation of air pollutants emission limits.

1: Steam boiler steam pressure the higher the better selection pressure, depending on the user's requirements. Vapor pressure, safety pressure member Advantageously, the energy consumption is low; but the steam will be relatively worse quality, low enthalpy, humidity, may be difficult to meet the disinfection, sterilization, culture, heating and power needs. And the high vapor pressure, energy consumption is high, the corresponding steam equipment, piping and valves the pressure is high, the maintenance requirements are also more, the production of steam, the heat transfer process, a large leakage loss. Meanwhile, high-pressure steam as the steam pressure is increased to carry the increased salinity, so salinity these waterwall tubes, pipe tobacco, and other drum heating surface fouling, overheating, foaming, clogging even increase the possibility of squib. Salt steam to steam turbine flow area will decrease, reducing the efficiency and seriously affect the heat transfer. Thus, fireman must operate in accordance with operation of the steam pressure, the steam pressure fluctuations generally allows a value between 0.05 ~ 0.15MPa.

2: the higher the boiler water level was considered safe water level is higher, the boiler water is not easy, security is also guaranteed. In fact, this is a misconception, the water level is too high, steam and humidity increase, poor steam quality, steam equipment will harm and production results. Industrial boilers, a moisture vapor sterilization or incubation with a large amount of steam also increased salt, or culture for a long time ranging from sterilization, steam consumption increase, ineffective, decreased production culture; weight is not reached the purpose of disinfection or cultured biological products contaminated scrap, even pipes, water hammer occurs apparatus. For utility boilers, steam moisture capacity, the steam turbine last stage blades will be erosion, there may appear Priming pot, water shock severe enough to cause harm equipment and personal safety. Thus, the pot water level should be maintained within a fluctuation range of ± 50mm well.

3: Some people think the better fuel plus fuel plus the more productive the greater the amount of steam. Little do they know too much fuel into the furnace, the effect will be counterproductive. When a certain amount of air and the excess amount of fuel, the furnace will produce a large amount of incomplete combustion, resulting in energy waste. People often see the dark furnace flame, weakness, and black smoke chimney, mostly for this reason. In severe cases, there will be fire pulverized coal, oil furnace secondary combustion occurs, burst pipes until shutdown. Therefore, the ratio of fuel and air volume should be adjusted appropriately, typically by looking at the fire, smoke color look, see table indicates the amount of oxygen determined. When the flame in the furnace as a bright yellow, pale gray smoke chimney to take, stable vapor pressure, wind coal showed appropriate ratio, good combustion.

4: Dial stirring the fire, the better the fire is commonly used in industrial boilers manual method. By stirring the fire, can be eliminated crater, reduction furnace from the fire and the fire bed smooth, homogeneous combustion, strong. But too much stirring the fire, but will reduce the overall thermal efficiency; this is because when stirring the fire, a lot of cold air into the furnace, reducing the average temperature of the furnace section of the flame. At the same time, increase the heat losses, an increase in the number of black smoke chimney, pollution of the environment. In addition, when stirring the fire, the staff is also susceptible to flame radiation, burns, fire-resistant layer is also susceptible to dial hearth fire damaged tools, increased furnace building maintenance workload. Therefore, the fire should be allocated as needed, to minimize the appropriate dial.

5: the bigger the better furnace pressure and furnace pressure is reflected in one of the boiler combustion conditions is normal or not an important parameter. Operating the boiler furnace negative pressure should be maintained between 10 ~ 20Pa, too great a negative pressure results in: increased leakage furnace, heat losses increase; wind increased electrical energy consumption; fly ash increased the wear along the heating surface; reduced the furnace heat of combustion efficiency. Most gas-fired boiler designed to run slightly positive pressure to increase the combustion rate. Operation, the furnace pressure becomes positive, even increasing the wind is still difficult to maintain the chamber negative pressure, said system failure or the wind furnace wall tubes, superheaters and other soft drinks leakage; fire furnace, the furnace pressure is first reflected table violent swing to the negative direction flung head. Therefore, the furnace pressure must be run according to the provisions, or should pinpoint the cause.

6: sewage longer the better spoken here regularly refers only to the sewage discharge rather than continuous blowdown. Periodic sewage mainly refers to the existence of negative bottom of the boiler slag, dirt and corrosion products, reduce furnace tube fouling, prevent clogging and reduce the salt content of the water boiler, heat transfer enhancement effect. One would think that the longer the discharge time, impurities will be discharged bottom of the pot the more, the better sewage, it is not. Sewage long time, a waste of a lot of heat, affect heating steam pressure; two pairs of boiler water circulation unfavorable, water wall tube burst will occur in severe cases. Thus, the sewage must be periodically according to "ground discharge, the discharge less uniform row" principle, provided hand operation. General Provisions at least once every eight hours of sewage, sewage each time shall not exceed 30s, overtime is strictly prohibited.

How much do you know about product performance vertical industrial diesel fired steam boiler for sale? Vertical steam boiler Product Description: vertical steam boiler, furnace various comprehensive domestic technological transformation, absorbing international advanced technology, the introduction of a new generation of horizontal oil (gas) boiler, product design has been applied for patent, pot head by a shell , boiler shell, U-ring composition, furnace head, lateral pipe, tube flying rocks.

Electric heating the core member is electrically heated boiler, directly determines the life of the boiler, to select a non-metallic electrical heating tube (such as a ceramic heating pipe), because it is resistant to the load, a long life, and a water separation structure, the boiler Wing no leakage. Combustion boiler using conventional techniques, the medium input from the door opening, an upper portion of the combustion grate, the furnace flue gas through multiple lateral flushing water, the carbon black and the rising process of fine soot particles are multilayer tube blockage, reducing the operating speed. Falls on the grate is re-smoke combustion, combustion flue gas discharged to the atmosphere through a stack. Performance: placed on top of the hearth grate boiler U-shaped scraps, the direct flame furnace and flush mounted tube furnace bending cylinder; structural characteristics of the boiler is to bend the vertical inner elbow installed in the furnace, increasing the radiation heating area. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. But because the degree of water-cooled furnace, the furnace temperature is reduced accordingly, generally applicable to coal burning quality. If you add the refractory bricks in the furnace, the coal may be lean combustion at higher temperature in the furnace. Preferably water cycle, each portion of the flue gas scrubber are cooled by, unitary structure having a good elasticity.
