However, this flue gas waste heat recovery power generation device only uses the high-temperature flue gas from the heat-conducting oil boiler to heat the cold water into high-temperature water, and then directly discharges the high-temperature flue gas into the atmosphere. The power generation system also needs an additional waste heat boiler to heat the warm water into steam for the steam turbine to generate electricity

The invention discloses a heat-conducting oil boiler waste heat power generation system. The heat-conducting oil boiler waste heat power generation system comprises a furnace body, a spray nozzle, a flue gas pipe and an air pipe, wherein a furnace hearth for heating heat-conducting oil is arranged inside the furnace body; the spray nozzle is arranged in the end wall of one side of the furnace body and is used for spraying fuel and combustion air into the furnace hearth for combusting and releasing heat; the flue gas pipe is connected to the end wall of the other side of the furnace body and is used for discharging flue gas from a flue gas outlet of the furnace body to a chimney; the air pipe is connected to the spray nozzle and is used for conveying the combustion air to the spray nozzle; the heat-conducting oil boiler waste heat power generation system further comprises a water steam circulating power generation circuit; the water steam circulating power generation circuit comprises a steam generator arranged inside the flue gas pipe, and a steam turbine connected with the steam generator through a pipeline.
Description
technical field [0001] The invention relates to a waste heat power generation system, in particular to a boiler flue gas waste heat power generation system. Background technique [0002] In the face of increasingly severe environmental problems and energy crises, the whole world is vigorously advocating energy conservation and emission reduction, especially for industrial kiln related industries with serious energy consumption and pollution. Factors that personnel must consider when designing such equipment. [0003] Taking the heat transfer oil boiler as an example, the flue gas temperature at the flue gas outlet usually reaches about 400 degrees Celsius. If these high-temperature flue gases are directly discharged into the environment, it will not only cause energy waste but also cause a certain degree of damage to the environment. [0004] For example, China Patent No. 200820139475.9 discloses a flue gas waste heat recovery power generation device, which is composed of ...
