Long type charcoal kiln

Abstract

The present invention relates to a long-type charcoal kiln. It includes three portions of combustion chamber, charring chamber and chimney. The front side of combustion chamber is connected with air inlet and fuel inlet, and its rear side is connected with arched charring chamber, said chamber is equipped with material inlet and material outlet, the rear end of said kiln body is equipped with a chimney, and the chimney flue is connected with connection flue with control valve. Said invention can be used for producing bamboo charcoal and wood charcoal.

Description

technical field [0001] The invention relates to a wood and bamboo carbonization kiln, which is an extended carbonization kiln which can be single or connected in series to form a compound. Background technique [0002] Using wood as raw material, charcoal is produced by smoke dehydration and dry distillation carbonization processes, and is mostly fired in earthen kilns to reduce the cost of kiln construction. In recent years, there are not many reports on special kilns for producing bamboo charcoal with bamboo as raw material. my country's "Forestry Science and Technology Development" in 2002, the 16th, the 5th, published "the improved earth kiln production bamboo charcoal process and technology" of Mr. Wang Weilong and Hua Zhaohui. The structural diagram of an improved bamboo charcoal earthen kiln was announced. The cross section is gourd-shaped. The inner height of the kiln is nearly 3 meters, the width is more than 3 meters, and the length is more than 4 meters. There is...

Problems solved by technology

The height of the kiln is large, the convection distance of the hot air up and down is long, and the carbonization of the bottom and the top is not easy; the bottom of the carbonization chamber and the two side walls have no flue, the transmission of hot air is hindered, and the length of the kiln is limited, and it is not easy to be connected in series. Extended type; due to the inner height of the kiln and no flue at the bottom and side walls of the carbonization chamber, the convection and transfer of hot air are uneven or blocked, resulting in high energy consumption and long production cycle. It takes 16 days to leave the kiln, which affects production efficiency.
