high pressure industrial gas fired steam boiler

high pressure industrial gas fired steam boiler

Classification and distinction and design a gas boiler, gas boiler gas boiler classified in accordance with the fuel can be divided into natural gas boilers, boiler city gas, coke oven gas boiler, liquefied petroleum gas boilers and gas boilers; according to the function can be divided into gas boiler water , gas hot water boiler (gas heating boiler comprising a boiler and bath gas), gas high pressure industrial fired steam boiler and the like; can be divided according to the structure of vertical gas boiler, gas boiler horizontal; in accordance with the process can be divided into a single flue gas boiler and tris backhaul backhaul gas-fired boiler. Second, the difference between fuel oil-fired boiler fuel boilers and gas boilers is fuel (such as diesel, oil, kerosene, etc.), fuel gas-fired boiler to gas (such as natural gas, city gas, biogas as well as liquefied petroleum gas, etc.), depending on the boiler What fuel burning device called a burner, boiler gas burner configuration called gas-fired boiler, oil boiler burner configuration called oil-fired boiler, oil-fired boiler and gas boiler difference is that what fuel burners. Third, the design of the boiler furnace by the gas boiler structural design pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination and beautiful form. Vertical-mounted boiler combustion at the burner, combustion of the fuel within the positive pressure furnace, baffle interposed smoke tube, slow smoke evacuation rate, to strengthen the heat exchanger, the heat furnace to ensure maximize fuel combustion water, improving the thermal efficiency of the boiler; horizontal wet back boiler full three pass structure, the length of the flue gas flow, reducing exhaust gas temperature, the whole corrugated furnace provided, so that the flame produced a strong turbulence to improve the heat transfer coefficient strength, and effectively It is prevented due to thermal expansion and contraction of metal results in a reduction of the life of the device; smoke tubes of large diameter and large pore bridge the gap, the boiler at equal time scale coating thin and easy to clean.

Fuxin City, Liaoning Province, Liaoning provincial government to respond positively to national policies according to the latest requirements, increase the intensity of atmospheric pollutants have increased in terms of the number of personnel or subsidies. Now funds raised 24.08 million yuan to support the removal of loose coal and coal-fired boiler control project.

According to statistics, since the fall of 2017, a total removal of Fuxin coal-fired boilers 488 units, a total of 1020.085 tons of steam, subsidies for 21.08 million yuan. At the same time, actively carry out the bulk coal Fuxin treatment project, the replacement of energy-saving small boilers 2,000 subsidy capital of 300 million yuan.

And, Fuxin City, developed a series of measures to scrutiny. To strengthen the management of special funds to ensure the flow of funds security, Fuxin City, the boiler license, inspection report and environmental impact assessment procedures to establish a furnace of a file basic information, to complete the formalities boiler users comply with the removal of subsidies standards, timely payment of subsidies to users hands.

After the implementation of removal of loose coal and coal-fired boiler control project implementation, Fuxin City air quality of the environment and the urban fringe have been greatly improved. According to the survey, this year, the average concentration of PM2.5 Fuxin City 35 micrograms / cubic meter, improved 12.5% ​​year on year; PM10 average concentration of 67 micrograms / cubic meter, improved 17.8% year on year; air quality compliance rate of 81.6%, an increase of 4 %.

Fuel gas boiler automatic instrument sets the control means are included which according to the "industrial boilers Complete supply" and provides fuel gas boiler automated instrument packages supply shall include at least the following: (1) evaporation of 4t / h and 4t / h or less boiler 1 ) detection. Water gauge, vapor pressure gauges (including saturated and superheated), water pressure gauge, water thermometer, thermometer smoke, steam flow rate calculation (including less than evaporation lt / h boiler). Oil temperature, oil pressure, oil level indication, calculates fuel (gas boiler as temperature, pressure, gas), furnace exit gas temperature indication. Evaporation of 4t / h boiler flue gas oxygen content should have, furnace pressure, temperature economizer export indication. 2) regulation. Position of formula (only for non-economizer of the boiler) or continuous feedwater automatic control, automatic adjustment of a combustion boiler the combustion of heavy oil should automatically adjust the oil temperature, air pressure gas boiler there should be automatically adjusted. 3) alarm and protection. High and low water level indication and alarm, low water level limit protection, over-pressure steam indication, alarm and protection, flame protection furnace, fuel gas overpressure protection or low temperature alarm and protection. 4) Other. Auxiliary electrical control box, gas boilers should be equipped with explosion-proof electrical control equipment. (2) evaporation of 6t / h and above 6t / h boiler 1) detected. Water gauge, vapor pressure gauges (including superheated saturated), water pressure gauge, water thermometer, thermometer, smoke, water, steam pressure, water pressure indicator, calculated water flow, steam flow indication, recording and computing, oil temperature, oil pressure, oil level indication, indication and calculating the amount of oil (gas boiler as temperature, pressure, gas), economizer inlet and outlet water temperature indication, furnace exit gas temperature, exhaust gas temperature, air pressure, furnace pressure indication, Sheng Mei an inlet, an outlet indicated negative, indicating flue gas oxygen content, there is an outlet air temperature should be indicative of the boiler air preheater, the boiler superheater, there should be recorded and the superheated steam temperature indication. 2) regulation. Continuous automatic adjustment of water supply, drum, induced draft fan damper flap opening remote control, remote pump control valve (an intake gas boiler control valve), a heavy oil combustion boiler should automatically adjust the oil, gas boiler should automatically adjust the air pressure, there is superheater boiler there should automatically adjust the temperature of superheated steam. 3) alarm and protection. High and low water level indication and alarm, low water level limit protection, over voltage protection and alarm indication of heart steam, oil accident alarm system, furnace flame protection, fuel gas overpressure protection or low temperature alarm and protection. Boiler superheater should have more limited temperature of superheated steam and an alarm indication. 4) control and the other. Drums, Fan, and start and stop the pump interlock control program, drum, fan baffle opening damper indicated, shall be provided with explosion-gas boiler electrical control equipment.

Maintenance of oil-fired boiler! What oil-fired boiler include? Fuel oil-fired boiler comprising a boiler water, hot water boiler fuel, the fuel heating boiler, oil bath boiler, and high pressure industrial fired steam boiler fuel, gas oil refers to the boiler fuel (such as diesel, kerosene), heavy oil, residual oil or crude oil fired boilers. Maintenance of oil-fired boilers? After conducting oil furnace shut until the furnace cooled water to the boiler water below 70 ℃ exhausted, the internal completely remove the dirt, washed away, all manholes, hand holes, valves and other pipeline tight blockade, and with a blind plate and running boiler completely isolated. After all of the alkaline solution is added, and then injected into the soft water boiler, until the water coming out from the highest point till the boiler, the water supply valve is closed, note that the average mixing an alkaline solution inside the boiler.
