RU1795230C - Method of sawdust burning - Google Patents

Abstract

Usage: the method relates to refueling and burning fuel in heating furnaces, mainly greenhouses, as well as rooms. SUMMARY OF THE INVENTION: A horizontally rectangular bar is installed in the lower part of the furnace, and vertical rods adjacent to it are installed. The first is placed through the door of the combustion chamber, the second - through the hatch from above. After that, the entire furnace volume is filled with fuel, for example, a mixture of sawdust and wood chips. In this case, the fuel is compacted. After filling the furnace with fuel, the rods are removed. Then a fire is kindled in the furnace space and after the start of sustainable burning, the air supply is finely controlled, achieving slow burning of a hermetically sealed bed. Fuel gradually burns out from the bottom up, forming a combustion chamber with a vault. With the correct selection of the combustion air supply mode, it lasts several days with moderate heating of the furnace body.

Description

The invention relates to methods for burning sawdust and other sealed fuel in heating furnaces.

A device for burning sawdust is known having a sealed furnace with an upper opening in the housing for loading sawdust. The furnace has an adjustable air supply device and a rack for restricting the combustion space. Sawdust is loaded into the furnace, compacted and burned at a controlled air supply.

However, the known device does not allow to increase the duration of combustion, since the furnace grate forms a furnace chamber along the entire height of the furnace and promotes intense burning of sawdust.

An object of the invention is to increase the burning time of sawdust.

The goal is achieved in that in the method of burning sawdust by loading into a sealed bed through the upper hole in the housing, sealing and burning with controlled air supply, the sealing is carried out with the formation of vertical through channels using removable rods and a horizontal channel using a bar.

The method is carried out as follows.

A rod in the form of a bar with a smooth surface is installed horizontally on the bottom of the furnace body through the lower door. Through the upper hatch, one or more rods are installed vertically on it over the entire height of the hull.

Then, through the upper opening, the furnace is filled with sawdust and compacted.

After filling the furnace with sawdust, the rods and bar are removed. At the same time, they form a combustion chamber and vertical smoke channels. After closing the upper hatch, fuel is ignited, and the door is hermetically closedX |

yut. The burning rate is maintained by a controlled air supply.

Sawdust forms a non-destructive arch, which moves upward as it burns out. Flue gas through

vertical channels are removed through the holes: the main pipe.

According to the proposed method, the sawdust is quenched in a furnace with a volume of 180 dm3 up to 96 hours at a case temperature of 60-80 ° C.

Claims (1)

The claims and with the fact that, in order to increase the duration of combustion, compaction is carried out with the formation of vertical through channels with the help of removable rods and The method of burning sawdust by loading into a sealed furnace through the upper opening in the housing, sealing and burning at 15 horizontal channels using a bru-controlled air supply is different. . and with the fact that, in order to increase the duration of combustion, compaction is carried out with the formation of vertical through channels with the help of removable rods and horizontal channel with the help of a bar. .
