Transformation of 20 Ton Circulating Fluidized Bed Boiler into Gas Boiler

Question details (performance) :

Although the boiler renovation work is drawing to a close, there are still some users to consult. For example, this user is currently using a 20-ton fluidized bed boiler, but also because the coal fuel is not up to the standard, ask if it can be changed into a gas boiler. The customer introduced that the design pressure of this fluidized bed boiler is 1.6MPa. It has only been used for 3 years and can be improved better. If the new 20-ton gas boiler cannot be improved, how much will it cost? How much floor space does it need?

The editor here clearly tells us that it is not easy to change a 20-ton circulating fluidized bed boiler into a gas boiler. The 20-ton circulating fluidized bed boiler and the 20-ton gas-fired boiler are two completely different types of boilers. If retrofitted, almost all of them will need to be retrofitted, which will cost a lot of money, material and energy. If we consider installing a gas-fired boiler, we might as well install a new one directly.

If the users consider the transformation, the 20-ton CFB boiler can try to change coal to biomass fuel, because the CFB boiler furnace type fuel can burn both coal and biomass fuel, and the parts changed by the transformation are relatively small. If the local supports the use of biomass boilers, coal to biomass is a good feasible scheme.

When the enterprise considers the boiler renovation again, we should consider whether it is worth the renovation. We need to comprehensively consider the service time and thermal efficiency of the original fluidized bed coal-fired boiler, the thermal efficiency and operation cost of the reformed boiler, etc. If you have any consideration about boiler renovation and new boiler installation, please consult us.
