Tunable energy-saving firewood stove

Abstract

The invention discloses a tunable energy-saving firewood stove. The stove body is provided with a stove core, smoke collection flue and a smoke discharging channel, a firewood feeding tube is upright arranged in the stove body and is parallel with the stove core, the feeding port of the firewood feeding tube is arranged at the upper end, the bottom of the firewood feeding tube is provided with a grate, the lower side wall of the firewood feeding tube is provided with a fire crossing, the fire crossing is communicated with the lower part of the stove core cavity by a flame path extending upward in inclined way to form a furnace, the stove body below the grate at the bottom of the firewood feeding tube is provided with an ash catching box used for closing inlet air from the grate, so that the firewood feeding tube and the furnace form a U-shaped channel, the side wall of the firewood feeding tube is a hollow interlayer, the hollow interlayer is a pressure box used for generating steam, the two sides of the fire crossing of the firewood feeding tube are respectively provided with a steam spraying device, the steam spraying device is communicated with the pressure box, and a regulating valve used for regulating and controlling air current throughput is arranged at the smoke discharging channel. The invention can cause combustion air to form powerful combustion air current and enhance fire behaviour, and firepower can be regulated, and energy conversation can be realized.

Description

technical field [0001] The invention relates to a wood-burning stove, in particular to an adjustable energy-saving wood stove. Background technique [0002] In the existing direct-fired wood stoves that use firewood as fuel, the feed inlet of the old-fashioned wood stove is directly set on the furnace wall, and the firepower is determined by the amount of firewood burned. This old-fashioned direct-fired wood stove consumes There is a lot of firewood, which is a huge waste. Later, someone designed an adjustable firewood stove that can reduce the consumption of firewood. This kind of firewood stove is equipped with a grate at the bottom of the furnace. It enters the furnace directly from the feed port and burns on the grate, and the combustion-supporting air enters from the air inlet below the grate, passes through the grate, and helps the firewood to burn in the furnace; or blows into the air inlet with a blower, and passes through Increase the air intake to promote the bur...

AI Technical Summary

Problems solved by technology

However, the energy-saving effects of these direct-fired wood stoves are not obvious enough. The former has less firepower and takes a long time, and can hardly save energy; Electric energy, energy saving is of little significance

In particular, the firepower of the direct-fired wood stove without blower cannot be adjusted and controlled after adding a certain amount of firewood, and the firepower can only be controlled by adding or subtracting the amount of firewood. Constantly adding or withdrawing firewood brings more troubles to users
