What are the common type gas steam bituminous coal boiler bituminous coal boiler manufacturer guwahati have? Common types of gas steam boiler is as follows: fuel (gas) is oil or gas as fuel, burning the fuel using a burner to heat the gas as steam carrier. Structure is generally divided into two kinds of vertical, horizontal, mainly based on these two forms of device space height. Gas based on coal as fuel, gas and steam as a heat carrier. Hand generally divided into vertical burn, horizontal cylindrical type, three kinds of gas fired horizontal plane structure, mainly based on labor intensity stoker thereby form these three points. For electric heating electric heating oil furnace, heat is generated and transmitted by the electrical heating element is immersed in the gas and steam to steam gas medium by the circulation pump to force liquid recycle gas steam, with a heat transfer to or more heating equipment, heating equipment after unloading, re-circulation pump, back to the heater, and then absorb heat, heat transferred to the device, again and again, to achieve a continuous heat transfer the temperature of the heated object rises, the heating to achieve process requirements.
75 ton CFB boiler can fire solid / liquid / gas fuel, such as bituminous coal, brown coal, anthracite coal, wood,heavy oil, etc. Also, combustion efficiency is pretty high.
PM2.5 is frequently mentioned in recent years, and its main premise was that the formation of NOx, according to the latest research results show in Beijing, PM2.5 and NOx emissions due to the formation of more than 50% of the total proportion of PM2.5. Because of a large area of coal to gas projects in recent years, the country's use of gas-fired bituminous coal boiler bituminous coal boiler manufacturer guwahati more than 50 million units in the Beijing area, gas boiler emissions will soon exceed the vehicle, as the primary sources of NOx in Beijing, so Beijing EPA first proposed the strict NOx emission standards: Beijing new boiler to perform emission limit of 30 mg / standard cubic meter for boilers with high-pollution fuel combustion zone ban, the implementation of emission limit 80 mg / standard cubic meter . The standard is much higher than the European emission standards for boilers, to the world's most demanding emissions standards in Southern California to move closer to the boiler.
Environmentally friendly gas-fired bituminous coal boiler bituminous coal boiler manufacturer guwahati combustion gas combustion five characteristics: In recent years, many cities frequently haze, caused widespread concern and heated debate. China is in the energy structure adjustment period, the task is urgent, the situation is very grim. Energy saving boiler gas boiler is the time to show their talents, its good energy efficiency and excellent environmental capacity, more and more enterprises of all ages. Here we analyze the characteristics of its advantages from the combustion of gaseous fuel. The fuel gas is a highly efficient, clean energy, its relatively low ignition temperature, the flame may spread rapidly to all parts of the furnace, the rapid combustion, facilitate gas, mixed with the combustion process is automatic, has the following characteristics: (1 ) virtually zero pollution combustion characteristics coupled with substantially does not produce ash, nitrogen content and sulfur content should be much lower compared to the fuel oil and coal, flue dust contained in the combustion rarely, very help protect the environment, essentially non-polluting combustion, even the most stringent environmental requirements of the region also ease of use, while gas fuel delivery pipes are based, will not produce ash, during transportation and storage leakage of harmful gases, dust and noise pollution does not occur. (2) facilitate adjustment of combustion. Transport pathways is the fuel gas conduit, through the valve, damper adjusted accordingly, adjust the air consumption can be achieved quickly adapt load changes, low oxygen combustion can be realized, thereby improving the thermal efficiency of the boiler. (3) Good job. Compared with the fuel oil, fuel gas from the transport duct, direct supply, eliminating the sump, fuel tanks and other household members. In particular compared to the heavy oil fuel, eliminating the need for heating, thermal insulation and other aspects. Gas system is relatively simple, the operation is relatively easy to manage, easy to automate. (4) easy to adjust the amount of heat. When LPG combustion, part of the air is added, to avoid the part of both the explosive range, you can adjust the amount of heat. (5) There are some disadvantages gas fuel, when mixed with a certain proportion of air, it will form an explosive gas, most of the fuel and the gas composition to humans or animals asphyxia toxic, so the security is very high. Boiler attaches great importance to the security of energy saving gas boiler in the production, testing process strictly guard the quality, as long as the practices in use, accidents will not happen.
