Example Embodiment

[0018] Referring to the accompanying drawings, reflecting a specific structure of the present invention, the biomass charcoal production and heating system includes sixteen kiln bodies 201 arranged in a matrix of 4 rows×4 columns, and the kiln bodies 201 are opened on the ground 200 Below the cellar structure. The spacing between each kiln body is 40-50 cm. A pre-combustion and heat-conducting tunnel 205 is set between the two rows of kiln bodies 201, and one end of the two pre-combustion and heat-conducting tunnels 205 is connected to the general heat-conducting tunnel 206. Two heat supply pipes 209 , the first heat supply pipe 210 is connected to the furnace of the gas boiler 212 , and the second heat supply pipe 209 is connected to the heater of the preheating water tank 211 of the gas boiler 212 . The combustible gas in the carbonization process is acted by the boiler furnace fan, and enters the gas boiler furnace through the pre-combustion heat conduction tunnel, the tot...

Abstract

The invention discloses a production and heat-supply system for biomass charcoal. The production and heat-supply system comprises a plurality of cellar type kiln bodies which are distributed in a matrix manner, wherein a pre-combusting heat-conducting pit channel is formed between two rows of kiln bodies. Combustible gas is influenced by a boiler fan in the carbonization process and enters a fuelgas hearth or a pre-heating water heating mechanism sequentially through the pre-combusting heat-conducting pit channel, a total heat-conducting pit channel, a split-flow door and a heat supply pipeline; the combustible gas is ignited in the pre-combusting heat-conducting pit channel, so as to realize decompression and explosion protection; by utilizing a cellar type structure, relatively good thermal insulation effect and airtight effect are achieved on the premise that the manufacturing cost is low; the energy consumption is substantially reduced; the quality of charcoal is greatly improved;the environmental pollution is completely eradicated, and the instant utilization of carbonized gas is safely and conveniently realized; and the system scale is convenient to be flexibly adjusted.

Description

technical field [0001] The invention relates to a heating system using combustible gas produced in the production process of biomass charcoal. Background technique [0002] Forestry waste such as branches, bark, wood processing scraps, firewood, twig firewood, curly bark, shavings, sawdust, etc., after crushing and crushing, the sawdust is hot-pressed into rods with rod-making equipment, and the rods are carbonized The prepared charcoal is called biochar or machine-made charcoal. Most of the current production practices still use the traditional earth kiln charcoal firing process to produce biomass charcoal. It takes 10-15 days from kiln installation to charcoal discharge. The production cycle is long, energy consumption is large, and the flue gas in the charcoal production process has not been rationally utilized. , and discharge into the air causing serious pollution. Contents of the invention [0003] The purpose of the present invention is to provide a compound syste...
