However, different gas boilers are used in different ways, so different gas boiler types also have different environmental effects.
1. Waste gas emissions and reduce environmental pollution
(1) Low exhaust gas emissions: The exhaust gas generated by anthracite pulverized coal boilers and electric steam boilers during the production process will be discharged with the flue gas, without producing smoke and dust, and meet the national emission standards.
(2) Low emissions: The exhaust gas emissions of gas steam generators are much lower than those of coal-fired boilers;
(3) High efficiency: The efficiency of the gas steam generator reaches more than 99%, which can save a lot of coal consumption and reduce carbon dioxide and soot emissions.
(4) Environmentally friendly and pollution-free: After heating, the hot water generated by the gas steam generator is directly used by people and will not cause pollution to the environment.
(5) Save fuel: Electric energy is one of the main fuels.
2. Use secondary air distribution
The air distribution method of the gas steam generator is to enter the air distribution device from the air inlet pipe according to the combustion needs, and then send the air into the combustion chamber through the fan, and at the same time send out part of the air.
The air distribution method has changed the original "single fan control system" and realized "secondary air distribution", which not only ensures safe operation of pressure, but also saves energy and reduces costs.
(2) Exhaust gas emissions from gas steam generators: Pollutants such as smoke, hydroxides and carbon dioxide generated during the operation of gas steam generators are forced to be recovered and purified before being discharged through the exhaust pipe.
(3) Water used in gas steam generators: Circular heating is used to convert thermal energy into water energy, and the calcium and magnesium ions in the water are converted into carbonates and precipitated, so that the water quality meets sanitary standards.
(4) Environmental protection effect: The use of air-distributed gas steam generator can purify the hydroxide gas generated by combustion through the exhaust gas discharge equipment and discharge it through the chimney; the use of natural gas steam generator can produce in a closed area without the emission of harmful substances .
3. The furnace has a large heating area and high thermal efficiency.
The heat generated by the gas steam generator is transferred to the drum through the heat exchanger, and the steam in the drum continuously heats the fluid in the pot. However, since coal-fired boilers have fixed grates, the heating area of the boiler is small, generally around 800 mm.
The gas steam generator uses floating grates or semi-floating grates, which increases the heating area by 2-3 times; while ensuring thermal efficiency, the heat exchange efficiency of the furnace is greatly improved, making the boiler thermal efficiency reach more than 85%.
The above is for natural gas steam generators, so how much waste gas will gas steam generators produce? The gas steam generator produces gases such as high-temperature and high-pressure water vapor and saturated steam.
4. Large steam output and wide application range
The steam output of the gas steam generator can reach 300-600 kg/hour, so it can meet more production process needs. In addition, natural gas has certain environmental pollution problems during transportation, and the country has currently banned the use of gas boilers. So besides using gas boilers, what other ways can we reduce environmental pollution?
