Double-medium waste heat boiler

Abstract

The invention provides a double-medium waste heat boiler. The double-medium waste heat boiler provide superheated steam for industrial production and meanwhile can provide hot water for heating, accordingly can effectively reduce the purchase and operation cost of the boiler and greatly reduce energy consumption and pollutant discharge. The double-medium waste heat boiler comprises a waste heat boiler flue and a steam dome, wherein the waste heat boiler flue is horizontally installed on a support, a waste heat high-temperature smoke inlet is formed in one end of the waste heat boiler flue, a smoke outlet is formed in the other end of the waste heat boiler flue and connected with a chimney, a superheater, an evaporator and an economizer are sequentially arranged in the waste heat boiler flue in the smoke flowing direction, and high-temperature smoke flows into the waste heat boiler flue through the waste heat high-temperature smoke inlet, sequentially scours vertical pipe bundles of the superheater, the evaporator and the economizer and then is discharged into the atmosphere through the smoke outlet and the chimney. The double-medium waste heat boiler is characterized in that a convection section of an organic heat carrier boiler is further arranged in the waste heat boiler flue and is arranged at the rear portion of the economizer in the smoke flowing direction.

Description

technical field [0001] The invention relates to the technical field of waste heat boilers, in particular to a dual-medium waste heat boiler. Background technique [0002] The waste heat boiler is a boiler that uses the waste heat in the waste gas, waste or waste liquid in various industrial processes and the heat generated by the combustion of combustible substances to heat water to a certain working fluid, which can greatly improve the utilization of the heat released by fuel combustion. rate and has a good energy-saving effect. Conventional waste heat boilers mostly use a single heat transfer medium, such as waste heat steam boilers and waste heat organic heat carrier boilers. However, in actual production and life, it is often necessary to generate superheated steam through steam boilers as production power, and it is necessary to pass hot water. The boiler provides hot water for heating. In this case, if two boilers are installed, the equipment cost will not only be hig...

AI Technical Summary

Problems solved by technology

Conventional waste heat boilers mostly use a single heat transfer medium, such as waste heat steam boilers and waste heat organic heat carrier boilers. The boiler provides hot water for heating. In this case, if two boilers are installed, not only the equipment cost is high, but also the energy consumption is large, which cannot meet the current energy saving and emission reduction requirements.
