Hot blast stove adopting biofuel

Abstract

The invention discloses a hot blast stove adopting biofuel. Rice husks, straw, wood and other grain fertilizers serve as the fuel. The hot blast stove comprises a stove body defined by an outer frame and a base. A hearth located at the lower portion, a heating pipeline located above the hearth and a hot air chamber connected with the heating pipeline are arranged in the stove body. The upper end of the hot air chamber is connected with a hot air pipeline led to the outer portion of the stove body. A hot air outlet is formed in the tail end of the hot air pipeline. A smoke discharge draught fan is arranged at the upper end of the stove body. The smoke discharge draught fan is connected with a smoke outlet of the stove body through a smoke discharge pipeline. By means of the hot blast stove, the fuel such as the rice husks, the straw and the wood is used for combustion, cost is low, and environment friendliness is high; the occupied area is small, and moving is convenient; and a temperature control system is arranged so that the temperature can be effectively controlled, and heat supply is stable.

Description

Technical field [0001] The invention relates to the technical field of hot blast stoves, in particular to a hot blast stove using biofuels. Background technique [0002] The grain dryer is a kind of mechanical equipment widely used in the process of agricultural mechanization, and the grain dryer needs to be used with heating equipment. Most of the current domestic grain dryers use steam boilers, heat-conducting oil furnaces, burners or hot blast stoves to heat the dryers. Among them, steam boilers have the disadvantages of serious flue gas pollution, difficulty in handling coal slag, difficulty in controlling dust, difficult in desulfurization treatment, inflammable and explosive, etc.; heat conduction oil furnaces have defects such as multiple explosive factors and high operating costs; burners have easy nozzles Blocking leads to defects such as poor air flow, easy burnout and deformation of the tuyere, and easy fall of the nozzle. Hot blast stoves have now become the replace...

AI Technical Summary

Problems solved by technology

However, because biomass generally has the characteristics of high moisture content, large fuel size changes, and high ash content, the above-mentioned biomass hot blast stoves have defects such as uneven air distribution, incomplete fuel combustion, low thermal efficiency, poor smoke and dust removal, and unenvironmental emissions.
