Biomass height difference combustion chamber

Abstract

The invention relates to a biomass height difference combustion chamber. The biomass height difference combustion chamber comprises a combustion chamber shell, a feeding device, a main bed, N auxiliary beds, N buried pipes, a main bed air supply device and N auxiliary bed air supply devices, wherein the combustion chamber shell comprises an interior tubular chamber, N concentric annular partitions are arranged in the middle of the tubular chamber, the middle of the tubular chamber is divided into one interior circular main bed and N annular auxiliary beds by the N annular partitions, and the bottom of the interior circular main bed is communicated with the bottoms of the N annular auxiliary beds; the heights of the N partitions are gradually increased in a stepped mode from inside to outside of the axis of the tubular chamber; the N is an integer between 1 and 5; the feeding device is used for annularly spraying to-be-burnt biomass from an area just above the circular main bed on the top of the tubular chamber; the N buried pipes are respectively arranged on the side walls of the N annular auxiliary beds. The combustion chamber has the advantage of high combustion efficiency.

Description

Technical field [0001] The invention belongs to the field of combustion equipment, and specifically relates to a biomass high-low difference combustion chamber. Background technique [0002] Biomass can be burned and is often used as a fuel. The existing combustion equipment has low combustion efficiency, which makes the combustion of biomass incomplete, which not only wastes energy, but also brings certain damage to the environment. For this reason, people invented the high-low difference combustion chamber, also known as the high-low differential bed, mainly through the different wind speeds of the high-speed bed and the low-speed bed, to realize the fuel enters the main bed of the boiler from both sides of the furnace, and the bed material particles boil and burn on the main bed. The large particles sink down and burn at a lower position. Small particles overflow on the surface. Because there is a height difference between the high-speed bed and the low-speed bed, it is ensur...

AI Technical Summary

Problems solved by technology

The high-low difference combustion chamber has good combustion efficiency and anti-wear function of the buried pipe, but there are still some deficiencies, and its combustion efficiency needs to be further improved
