【Abstract】 Exhaust gas temperature is an important parameter to the boiler design, operation. According to the commonly used fuels, this article calculates the exhaust gas dew-point temperature of coal-fired boilers, oil-fired boilers and gas-fired boilers. Based on it, the author selects reasonable exhaust gas temperature, and analyzes the boiler thermal efficiency benefited from the exhaust gas temperature reduction.更多还原
