Research of combined cooling heating and power systems (9):Gas CCHP systems—the best way to substitute gas for coal

Aiming at the process of substituting gas for coal, queries the blind practice of using gas-fired boilers to replace coal-fired boilers. Thinks that there are three ways for substituting gas for coal, namely, gas-fired power station, gas-fired boiler and gas CCHP system. Analyses some problems existed in substituting gas for coal when gas-fired boiler is used as the first choice. Combined with project cases, illustrates that gas CCHP should be the best way to substitute gas for coal.
