Embodiment Construction

[0021] The specific embodiment of the present invention and working process will be further described below in conjunction with accompanying drawing.

[0022] The orientation terms such as up, down, left, right, front and rear in this application document are established based on the positional relationship shown in the drawings. If the drawings are different, the corresponding positional relationship may also change accordingly, so this should not be understood as limiting the scope of protection.

[0023] Such as figure 1 As shown, a hot blast stove includes a feed bin 1, a gasification chamber 2, a combustion chamber 3, a burnout chamber 4, an air mixing chamber 5, a fire grate 6, a separator 10, a tail flue 11 and a water seal tank 9 Wait.

[0024] The feed bin 1 is set above the gasification chamber 2, fuels such as biomass are fed into the gasification chamber 2 from the feed bin 1, gasification occurs in the gasification chamber 2, and the generated gasification gas i...

Abstract

A hot-blast stove comprises a gasification chamber, a combustion chamber, a burn-out chamber, an air mixing chamber, a fire grate, a tail flue and the like. The gasification chamber, the combustion chamber, the burn-out chamber and the air mixing chamber are sequentially horizontally parallelly arranged to form a reciprocating type material air flow channel. The fire grate is obliquely arranged at the bottoms of the gasification chamber and the combustion chamber. Primary air chambers are arranged at the bottom of the fire grate. The inclined bottom of the burn-out chamber is provided with a tertiary air pipe. A heat exchanger is arranged in the tail flue and used for heating cold air into hot air. The tail flue part in the front of the heat exchanger is provided with a primary cold air pipe, and the tail flue part at the rear of the heat exchanger is provided with a secondary cold air pipe. The hot-blast stove is long in material air flow channel travel, good in gasification and combustion effect, clean in flue gas and capable of acquiring hot air and hot flue gas.

Description

technical field [0001] The invention relates to a hot blast stove, in particular to a hot blast generating device for generating hot flue gas and hot air while biomass fuel is gasified and burned, and belongs to the field of thermal energy equipment. Background technique [0002] The low-temperature drying process of materials often requires a hot air generator to generate hot air. In order to obtain a heat medium with relatively stable parameters, a common hot air stove often first generates hot water through a combustion device, and then exchanges heat with air to obtain hot air. And this type of hot blast stove often generates a single heat medium: hot air. Contents of the invention [0003] The purpose of the present invention is to provide a hot wind generator, which simultaneously provides clean hot flue gas and hot air as heat medium. [0004] The present invention is achieved through the following technical solutions: [0005] A hot blast stove, characterized in ...
