Clean coal reversal combustion hot air furnace with partition plates

Abstract

A clean coal reversal combustion hot air furnace with partition plates comprises a combustion chamber, a smoke discharging pipe and shape coal beds; due to a smoke discharging port in the top face ofthe combustion chamber, an inner cavity of the combustion chamber and an inner cavity of the smoke discharging pipe are communicated, and the two center axes are collinear; the smoke discharging pipeis vertically arranged and is perpendicular to the top face of the combustion chamber. The radius of the inner cavity of the combustion chamber is 1.0 m to 1.2 m; the many rectangular partition platesare vertically arranged in the inner cavity of the combustion chamber; the transverse edges of each partition plate are 0.6 m to 0.7 m long; the inner vertical edges of the partition plates are on adownward extending face of the inner wall face of the smoke discharging pipe; the distance between the outer vertical edges and the side wall face of the inner cavity of the combustion chamber is 100mm to 150 mm; the corresponding shape coal bed is stacked between every two adjacent partition plates; the small arc faces of the shape coal beds are on the downward extending face of the inner wall face of the smoke discharging pipe; the outer vertical edges of the partition plates are on the large arc faces; and the inner cavity space defined by the downward extending face of the inner wall faceof the smoke discharging pipe is an ignition fire accelerant stacking area. The clean coal reversal combustion hot air furnace with the partition plates can be used for dense tobacco curing and scattered leaf tobacco curing. One-time coaling is adopted for the clean coal reversal combustion hot air furnace with the partition plates, 25% of coal is saved, the clean coal reversal combustion hot airfurnace with the partition plates can be attached to a process curve to generate hot air, and the draught fan temperature is 38 DEG C.

Description

Technical field [0001] The invention relates to a clean coal back-burning hot blast stove with a partition plate with the technical characteristics of open flame back-burning, high-temperature isolation, combustion-supporting fan start and stop, precise control of combustion and heating, etc., which is suitable for dense flue-cured tobacco and loose leaf flue-cured hot blast rooms in agricultural and rural areas Used by combustion heating device. Background technique [0002] With the increase in the scale of tobacco farming in China and the development of modern tobacco agriculture, intensive curing has been rapidly promoted and applied nationwide. Taking 2012 as an example, there were about 1.2 million intensive tobacco-curing rooms nationwide. According to statistics, more and more dense flue-curing rooms use tunnel furnaces based on the principle of dark fire and burning for heating. The tunnel furnace has a simple structure and low cost. It can be loaded with coal at one t...

Problems solved by technology

[0005] In order to overcome the shortcomings of the tunnel furnace, such as high temperature furnace gas reverse flow and burning combustion fan due to dark fire, low utilization rate of combustion air, hot air temperature not keeping up with the setting temperature of baking process, explosive combustion and low thermal efficiency, etc. Invented and designed a kind of technical features such as open flame reverse combustion, high temperature isolation, precise control of combustion and heating by starting and stopping of combustion-supporting fan, which meets the needs of my country's tobacco industry for saving labor and time, safety, economy, high quality, high efficiency, energy saving and environmental protection.
