Price of coal-fired boilers
Thread Content
What is the price of a 10-ton coal-fired boiler with a pressure of 10 kilograms, including all necessary accessories for desulfurization and denitrification? What is the difference in economic efficiency and investment costs compared to boilers that use gas or oil?
With such a vague question, it’s likely that no one will be able to give you an answer – it’s not clear whether it’s a boiler with a fluidized bed or a chain grate boiler Different manufacturers offer different quotes, and since the desulfurization and denitrification processes vary, there is a significant difference in prices as well.
Overall, the operating cost of coal-fired boilers is low, making them more economical than gas boilers. However, it depends on the subsequent processing steps: if material drying is required, coal was used in the past, which necessitated the use of heat exchangers and led to significant energy losses, with temperatures ranging only from 400 to 500 degrees. After switching to gas, heat exchangers are no longer needed, and the temperature can reach over 700 degrees, but the operating cost increases as well. Gas boilers are cleaner, while coal-fired boilers are dirtier
Now, few boiler manufacturers produce industrial coal-fired boilers. Can you get approval for a coal furnace? There’s no need to compare costs at all – burning coal is definitely much cheaper, although the initial investment for a coal furnace is significantly higher~
Coal-based systems have high construction costs but low operating costs, while gas-based systems have low construction costs but high operating costs； Coal-fired equipment is abundant, occupies large areas, causes significant pollution, and requires many workers. Gas-fired equipment is fewer in number, takes up less space, causes less pollution, and needs fewer operators.
