Is it feasible to change the coal-fired boiler to natural gas fired boiler?

Boiler occupies an important position in our country's production and life, and is widely used in textile industry, energy industry, building materials, construction industry, chemical industry, metallurgical industry, transportation and military industry. With the progress of air pollution control, a number of coal-fired boilers with substandard emissions will soon be eliminated, and it is a foregone conclusion to switch to natural gas.

Feasibility of changing coal-fired boiler to natural gas boiler

Coal-fired boilers are converted to natural gas, usually by dismantling old boilers and purchasing new natural gas boilers. Because the fuel calorific value of coal and natural gas differs greatly, the combustion efficiency is low, the heat loss is large, the control is inconvenient, and the transformation cost is high.

1. Green and environmental protection Natural gas is a green and clean energy source. Changing coal-fired boiler to natural gas boiler can reduce the emission of harmful substances such as nitrogen oxides from the root cause, and there is no need to invest a lot of money in tail gas treatment, worrying about the effect of tail gas treatment.

2. Energy saving and low carbon It is natural gas fuel, which can burn more fully, and the thermal efficiency of natural gas boiler can reach more than 98%. Coal-fired boiler is solid fuel, the thermal efficiency of chain boiler is 82%, and that of circulating fluidized bed boiler is 89%.

3. Cost

Compared with the original boiler transformation, it is more economical and reliable to use natural gas boiler instead of coal-fired boiler. Moreover, the gas boiler is relatively small in size, occupies a small space, does not need a coal storage warehouse, and has no smoke pollution.

It should be noted that the conversion of coal-fired boiler to natural gas boiler should ensure that the structural characteristics and area of the original coal-fired boiler room meet the relevant requirements of gas boiler installation. The related equipment used in the original boiler room, such as circulation system, thermal system and water treatment system, does not need to be overhauled, but it is necessary to ensure that the auxiliaries are basically in good condition.

Boiler recommendation

For the selection of coal-fired boiler to natural gas boiler, you need to consult a professional boiler manufacturer. As a professional manufacturer of industrial boilers, ZOZEN has Class A and ASME boiler manufacturing qualifications. Its product matrix covers many varieties and specifications such as gas boilers, biomass boilers, coal-fired boilers, organic heat carriers, circulating fluidized bed boilers, etc., and it is widely used in chemical, food, brewing, heating, paper making, printing and dyeing, rubber and other industries.
