Abstract

The invention discloses an efficient waste heat boiler. The efficient waste heat boiler comprises a smoke main flue, a combustor and a smoke mixing device. The smoke mixing device is connected with the smoke main flue and the combustor. The smoke main flue and the combustor are connected or disconnected in the smoke mixing device. Each of the smoke main flue and the smoke mixing device is provided with a temperature induction device. The combustor can automatically detect the temperature of the smoke main flue and the temperature of the smoke mixing device, automatically controls connection and disconnection with the smoke main flue and controls combustion of itself. Real-time monitoring of the smoke temperature is achieved through the combustor, the combustor is controlled to conduct effective combustion, and the heat exchange smoke temperature of the waste heat boiler is kept in the preset range. It is ensured that steam generated by the boiler reaches the temperature and pressure regulated by the process technology requirement, and the running load capability of the boiler is effectively improved.

Description

technical field [0001] The invention relates to the field of boilers, in particular to a high-efficiency waste heat boiler. Background technique [0002] Waste heat boiler refers to a boiler that heats water to a certain temperature by using the waste heat in waste gas, waste or waste liquid in various industrial processes and the heat generated by the combustion of combustible substances. Oil-fired boilers, gas-fired boilers, and coal-fired boilers with smoke boxes and flue waste heat recovery are also called waste heat boilers. Waste heat boilers can produce hot water or steam for use in other sections through waste heat recovery. However, due to changes in the process conditions of the production line, the exhaust gas temperature is high and sometimes low; the exhaust gas temperature produced by industrial kilns is unstable, and when the exhaust gas temperature is low, steam that meets the technical requirements of temperature and pressure cannot be produced, and the oper...
