Abstract
The utility model relates to an economical inclined bottom heating furnace. The heating furnace comprises a furnace body, wherein a mixed gas producer and a fan are arranged behind the furnace body; a gas burner is arranged in front of the furnace body and is connected with a furnace front hot air pipeline and a furnace front hot gas pipeline which are arranged above the furnace body; a gas outlet pipe of the mixed gas producer is communicated with the furnace front hot gas pipeline; and an air outlet pipeline of the fan penetrates through an air heat exchanger and then is connected with the furnace front hot air pipeline. Solid coal is combusted and gasified to form gas fuel through the mixed gas producer, so that the heating furnace is low in combustion cost and high in thermal efficiency, and the operating cost of the heating furnace is reduced.
Description
Technical field
The utility model relates to the industrial furnace of producing weldless steel tube, specifically a kind of economical inclined-bottom heating furnace.
Background technology
Inclined-bottom heating furnace is a kind of industrial furnace that is used for seamless steel tube production heating pipe commonly used.It is fuel that traditional inclined-bottom heating furnace generally adopts coal dust or Sweet natural gas, is that the price of fuel coal is low though adopt coal dust, and the thermo-efficiency of coal is low, and the running cost of stove is high; The employing Sweet natural gas is a fuel, though improved thermo-efficiency, the price of Sweet natural gas is high, and the running cost of stove is still high.
Summary of the invention
The utility model provides a kind of economical inclined-bottom heating furnace that reduces running cost to the problems referred to above.
Technical scheme according to the utility model: a kind of economical inclined-bottom heating furnace; Comprise body of heater; The rear portion of said body of heater is provided with mixed gas producer and blower fan; The front portion of said body of heater is provided with gas burner; Said gas burner links to each other with the stokehold hot-air duct and the stokehold heating gas pipeline that are arranged in said body of heater top, and the escape pipe of said mixed gas producer communicates with said stokehold heating gas pipeline, and the wind pipe of said blower fan links to each other with said stokehold hot-air duct through behind the air heat exchanger.
Said mixed gas producer and said water seal cleaning apparatus have two covers, communicate with said stokehold heating gas pipeline after the escape pipe parallel connection of the said mixed gas producer of two covers.
The escape pipe of said mixed gas producer is provided with the water seal cleaning apparatus.
The technique effect of the utility model is: the utility model changes into geseous fuel through mixed gas producer with solid coal fuel gas, and not only fuel cost is low, and thermo-efficiency is high, has reduced the running cost of process furnace.
