Abstract

The invention discloses a hot-air furnace, relating to the technical field of boilers. The hot-air furnace comprises a furnace body, a smoke outlet and an ash chamber, wherein the smoke outlet is positioned on the furnace body; the ash chamber is positioned under the furnace body; the inner part of the furnace body comprises a heating cavity provided with hot air pipes and a combustion chamber positioned under the heating cavity; the heating cavity is provided with an air inlet and an air outlet which lead to the outside of the furnace body; the ash chamber is provided with an ash outlet and an air blowing port which lead to the outside of the furnace body; the combustion chamber comprises a material inlet and grate bars positioned under the material inlet. The hot-air furnace is characterized in that refractory materials are built at the middle-lower part of the inner wall of the combustion chamber, and air supplying holes are arranged at the upper part of the inner wall of the combustion chamber; and channels are arranged in the refractory materials. The hot-air furnace disclosed by the invention has the advantages that the structure is simple, and the use is safe and convenient; and the refractory materials are built in the combustion chamber and a ventilating pipeline is added, so that the service life of the furnace body is prolonged, simultaneously the combustion is fuller and the heat efficiency is increased.

Description

A kind of hot-blast stove
Technical field
The present invention relates to the boiler technology field, specifically is a kind of hot-blast stove.
Background technology
Through long production practices, it has been recognized that to have only the hot blast of utilization as medium with carrier could improve heat utilization efficiency and the thermal technology makes effect biglyyer.Traditional electrical thermal source and steam thermal power often dispose many circulating fans in course of conveying, make it the final hot blast operation of drying or heat that still forms indirectly.The obvious existence of this process wastes energy in a large number and causes many shortcomings such as auxiliary device is too much, complex technical process.And bigger problem is, this thermal source is then felt simply helpless for the sort of requirement that needs higher temperature drying or baking operation.
Hot-blast stove as thermal power machinery begins extensive use in late 1970s in China, and it has become the regeneration product of electric heat source and traditional steam power thermal source in many industries.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of hot-blast stove of easy and simple to handle, long service life.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of hot-blast stove; Comprise body of heater, be positioned at the outlet flue of body of heater top, the grey thorax below the body of heater; Comprise the heating chamber that is provided with warm-air pipe, the combustion chamber that is positioned at the heating chamber below in the body of heater, said heating chamber is provided with air inlet, the air outlet outside body of heater, and said grey thorax is provided with and leads to body of heater outer ash hole, blast orifice; Said combustion chamber comprises charging aperture, is positioned at the fire bars of charging aperture below; It is characterized in that: the middle and lower part of said combustion chamber inwall has been built refractory material by laying bricks or stones, and the top of combustion chamber inwall is provided with wind complement port, is provided with passage in the middle of the said refractory material.
Said refractory material is a refractory cement.
Said passage is an intake stack.
Said wind complement port communicates with intake stack.
The invention has the beneficial effects as follows: the present invention is simple in structure, and is safe and convenient to use, in the combustion chamber, builds refractory material by laying bricks or stones and sets up ventilation shaft, when prolonging the service life of body of heater, also makes burning more abundant, increases heat energy efficiency.
