Built-in baffle whirlwind combustion wind disk

Abstract

The invention relates to a built-in baffle whirlwind combustion air disk, which comprises an annular air cavity, and a plurality of slanted baffles inclined to the same direction are arranged in the cavity of the annular air cavity, and the slanted baffles are arranged evenly and spaced according to the circumference. It is fixedly connected to the inner ring elevation of the annular air chamber, and the inner ring elevation of the annular air chamber is provided with a plurality of small ventilation holes communicating with the flame gathering port. The built-in baffle-type whirlwind combustion air tray can be placed on the upper mouth of the stove, and the fire gathering port is evenly equipped with rotating wind, so that the fire gathering port gathers the smoke and fully mixes it with the air for combustion, improving the thermal efficiency of the stove and achieving clean combustion. Purpose.

Description

technical field [0001] The invention relates to a built-in damper whirlwind combustion air pan, which is a combustion-supporting device for secondary air distribution of stoves. Background technique [0002] The winter in northern my country is cold, especially in rural areas. Because most of the farmers live scatteredly, it is difficult to realize central heating. However, due to economic factors, most farmers choose lignite, bituminous coal and other coals with relatively ordinary coal quality, and some farmers choose Local materials are used, and biomass such as firewood and plant stems are used as fuel. Most of these fuels need to be equipped with air to support combustion. Ordinary heating furnaces generally only have primary air distribution, or although there is secondary air distribution, but due to insufficient secondary air distribution or unreasonable air distribution, fuel combustion is incomplete and thermal efficiency is low, thereby emitting a large amount of s...
