3000kw electric mercial hot water boiler

Repair hot water 3000kw electric mercial hot water boiler: hot water boiler (hot water boiler) according to different fuels can be divided into electric water boilers, hot water boiler fuel, gas hot water boiler, coal-fired hot water boiler; widely used in hotels, schools, hotels , residential heating, domestic hot water bathing and other enterprises and institutions.

How to calculate gas consumption Gas steam 3000kw electric mercial hot water boiler Gas steam boiler air consumption how to calculate: there are a lot of users do not know how to calculate the gas consumption of gas steam boiler steam boiler gas before you buy, there are many user calls consultation, the issue it has been plagued by some users, this morning it decided to write articles about it again, "how gas consumption gas steam boiler computing", following on from me explain to you about the principles of operation of the gas boiler gas consumption formulas and gas boiler. 1. First, we first look at the gas steam boiler operating principle: the pressure of the fuel through the gas line is controlled by the flow valve through the ignition burner Automatic combustion air, the heat emitted by the heating surface of the boiler sufficiently absorbed (three return) flue gas (carbon dioxide and water) into the atmosphere through the chimney. 2. Gas-fired steam boiler fuel consumption cost analysis (we have a 4-ton gas-fired boiler, for example) fuel light oil and gas projects Rated evaporation 4t / h2t / h thermal efficiency of 92% to 92% fuel heating value 8500Kal boiler / Nm310300Kal / Kg fuel consumption amount 300Nm3 / h24Kg / h auxiliary mechanical and electrical consumption 11KW · H11KW · H fuel Price yuan / Nm3 yuan / Kg fuel costs per hour yuan per hour RMB auxiliary mechanical and electrical consumption costs the first year cost of fuel (million, according to 350 days / annualized) in the auxiliary equipment costs (million yuan, according to 350 days / year basis) of the total cost (million, according to 350 days / year basis) (Note: at 12 hours per day) 3 can be roughly summed up the table above to see a: full load per unit time difference of many operating costs, especially compared with the fuel gas. Of course, its operating advantages and disadvantages: the relative running disappointment source gas boiler in terms of impact, but the large-capacity electric boiler operating electrical equipment network difficult and requires a large-capacity transformer request by; fuel oil boiler by factors influence the larger. In terms of environmental protection, the most environmentally friendly power, followed by gas and oil. In terms of operating costs, natural gas is the most economical, followed by oil and electricity. Proposed conditional user preferred gas boiler, not only because of its low operating costs and environmental protection.

Tongchuan City, Shaanxi Province is located in Fenwei plain, it is China's major coal producing area, the unique geographical location determines the Tongchuan coal energy as one of the main economic development. Tongchuan coal to bring rapid economic development, but a large proportion of heavy industry, atmospheric pollution and other issues are very serious. "Winning Blue Sky Battle three-year action plan" published this year, Fenwei plain was a key governance areas. Coal City is not achieved coal, coal is not coal, promote clean heating, Tongchuan City is a serious problem.

Tongchuan party secretary said: "This year Tongchuan 4905 ex situ poverty alleviation relocation of the masses of resettlement housing has been fully completed and turnkey, the actual stay 3763, is a large-scale relocation of mass arrival of new homes in the first year."

After a preliminary investigation, Tongchuan City to improve people's livelihood and environmental protection together, launched a "warm life, warm hearts and minds" of warm winter action. Based on the concept of local conditions, it has been completed in 40 of the city's centralized settlements, reduce operating costs, clear charges. Mastery of natural gas household heating settlements, natural gas boiler wall encouraging people to self-heating; central village of rural resettlement and scattered resettlement households, encourage and guide them to use electric heating and cleaning of heating equipment. All use of clean heating devices are available to the masses 1000 yuan subsidy.

Clean heating, an impact on the masses warm winter, a relationship with Blue Sky Battle Action Plan. It is understood that the city of Tongchuan coal-fired boiler to achieve a global "clear" in 2017. 2018, Tongchuan City by town gas central heating and household heating, rural households in accordance with the appropriate air dispersion of the gas, should the electric power, should be hot is hot, use clean coal coal should guide the masses to reduce the amount of bulk coal use, and the use of clean energy and the masses of poor people winter heating subsidies. Currently Tongchuan City, completed a total clean energy alternative to coal for 27,897, of which 25,196 coal to electricity, coal to gas 2701, the city's clean heating rate of 82%, the basic realization of the coal city does not burn coal, coal is not coal.

According to Eco-Environment Department data show that 11 cities Fenwei plain mean concentration of PM2.5 in October this year to 48 micrograms / cubic meter, down 7.7% year on year. The lowest average concentration of PM2.5 is Tongchuan city, is 38 micrograms / cubic meter.

Gas, the working principle of a steam 3000kw electric mercial hot water boiler gas heating device (burner) to release heat, radiation heat transfer is first absorbed by the water wall, the Wall Boiling water, a lot of steam into the drum for generating steam separator (DC out furnace), separated the steam entering the superheater full, by radiation, convection method and continuous top horizontal flue furnace absorption, the flue gases heat the back pass, and the superheated steam temperature reached the requested work. Power generation boilers are generally provided with a reheater, steam is used to heat the work of the high-pressure cylinder, the reheater go out of the reheat steam, the low pressure cylinder continuously to generate power. Plain speaking, a steam boiler the burning of the fuel absorbs heat energy must be water parameter (such as pressure, temperature, etc.) of the steam device. Boilers and boiler furnace divided into two parts, the pot is filled with water to the metal container, the fuel is burning furnace section heat absorb water pot furnace and burning the fuel to steam, with the basic principles of almost boiling water, the pot equivalent kettle, oven stove equivalent. Horizontal gas steam boiler Schematic heating apparatus (burner releases heat, radiation is first absorbed by the water wall heat transfer, vaporization of water boiling water wall, a lot of steam into the drum for generating steam separator (DC out furnace), separated full steam enters the superheater, by radiation, convection method and continuous top horizontal flue furnace absorption, the flue gases heat the back pass, and the superheated steam temperature reached the requested work. power generating boilers are generally provided with a reheater, is used to heat the steam by the high pressure acting cylinder, and reheated steam reheater go out, the low-pressure cylinder continuously to generate power. plain speaking, a steam boiler the burning of the fuel absorbs heat energy must be water parameters ( the apparatus steam pressure, temperature, etc.) of the boiler and the boiler furnace is divided into two parts, the pot is filled with water to the metal container, the fuel is burning furnace section heat absorb water pot furnace burning fuel converted steam, boil water with the basic principle is similar to the equivalent of pot kettle, oven stove equivalent. vertical gas steam boiler principle diagram vertical gas steam boiler Furnace is an energy conversion device, the input energy to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, the boiler through the conversion of thermal energy must be externally output with steam, hot water or organic heat . used for power plant, boats, locomotives and mining enterprises. the main rationale original working passed to a boiler water in the container after use of the thermal energy released or the fuel burned in the industrial production of heat, the temperature of the water reaches the demanded or must steam pressure thermal equipment boiler in the "pot" and "furnace" two somewhat performed in conjunction with the water into the boiler in the future, the heat in the soda system boiler heating surface will absorb transferred to the water, the water heated to a bound of temperature and pressure generating hot water or steam, is drawn applied. in some incineration equipment, continued burning of the fuel heat release, high temperature flue gas occurs by thermal incineration of communication, transferring heat to the boiler heating surface, the temperature was gradually lowered itself, and finally discharged from the chimney classification steam boiler: a, divided by the fuel: 1, gas boiler, 2, oil-fired boiler, 3, gas boiler, 4, electric heating boilers, 5, atomic energy boiler, 6, waste heat boiler, etc., during the first four at most, the most common, the lowest operating costs of gas-fired boilers, but large area, environment pollution, the operator requested more; fuel gas boiler high degree of automation, operation cost is higher than gas, smaller footprint, fewer requests operator; electric heating boiler I have not had the operation, but the operation cost should be the highest, but a small boiler area, environmental best; other boiler is not introduced because they do not understand Second, by mode of heat transfer into the fuel gas-fired boiler is usually fire tube boiler water tube boiler, fire tube boilers, water, fire tube boilers and other. typical model: WNS series (horizontal burning boiler combustion chamber), the characteristics of such boilers: simple structure, an additional amount of evaporation is generally small (typically ten tons or less, there are also large, but usually do not exceed 35 tons), Kai boosting faster furnace, boiler water is relatively low request; gas boiler are usually water-tube boiler, water tube boiler high thermal efficiency, but messy configuration, the boiler high quality requested. Third, by additional pressure into the low-pressure boilers, pressure boiler, high pressure boiler Fourth, the use is divided into days boilers, industrial boilers, power generation, marine boilers.
