Energy-efficient fire coal multipurpose hot-blast stove

Abstract

The invention provides an energy-efficient fire coal multipurpose hot-blast stove, belongs to the stove accessory technical field, and aims to solve the problems that an existing hot-blast stove is unreasonable in structure, and low in thermal efficiency; the hot-blast stove body is a square tube type hot-blast stove body; the lower portion is provided with a combustion chamber having a stove door and fire bars; a hot air tube nest cover box is arranged in the stove cavity between the upper portion and an exhaust cylinder; a plurality of transversely arranged hot air sleeves are arranged in the hot air tube nest cover box; the exhaust cylinder is provided with an adjustable adjusting cover; the energy-efficient fire coal multipurpose hot-blast stove is novel in structure, and suitable for being applied to the breeding industry, plant production, processing industry and production workshops.

Description

Background technique [0001] At present, hot air stoves have been widely used in breeding industry, planting industry, wood processing industry, production workshop, etc. and are continuously developing. In the known technology, the existing coal-fired hot blast stove mainly adopts a combustion chamber at the bottom of a cylindrical furnace body, a heat exchanger with a vertical tube installed in the upper furnace cavity, and an induced draft fan is connected to the outside of the furnace body, and a hot air outlet is connected to the upper part. The coal-fired combustion chamber is heated by the heat exchanger and the air blown into the blower becomes hot air output. The coal-fired flue gas is directly emitted from the exhaust pipe, resulting in high exhaust temperature. Especially after a certain period of operation, the vertical tube heat exchanger in the furnace often causes serious dust accumulation and affects heat transfer, resulting in low thermal efficiency, but also lim...
