Biomass cooking and heating stove

Abstract

The invention provides a biomass cooking and heating stove. A burner in a conical structure is mounted at the top end of an inner container. A collector disc in an inverted cone structure is mounted at the top end of the burner. A baking tray is horizontally mounted at the joint of the burner and the collector disc. The burner, the collector disc and the baking tray are integrated. The braking tray seals the inner cross section of a stove body. The burner, the collector disc and the inner container are coaxial and are internally communicated with one another. The sidewall of the burner is provided with air holes. A gap between the inner container and the stove body serves as a secondary air passage. By secondary oxygen supply and complete utilization of waste heat, oxygen is supplied to primarily-burned gas in the inner container to allow the gas to secondarily burn in a semi-gasified manner, and burning efficiency is greatly improved. A special U-shaped flue system enables a flue gas discharge path to be longer and flue gas to stay longer in a flue, and waste heat is more sufficiently utilized; a flue adjusting plate allows a flue gas flow path and a flow direction to be adjusted during burning, and using is more facilitated.

Description

technical field [0001] The invention relates to a biomass cooking stove. Background technique [0002] In recent years, with the demand for new rural construction and energy conservation and environmental protection, the development and utilization of biomass stoves have attracted more and more attention, and are gradually being promoted and applied. At present, there are many types of biomass stoves on the market. There is a technical solution for a biomass stove that roughly includes a furnace body and a furnace liner installed in the furnace body. Biomass fuel is placed in the furnace liner for combustion and heating. There are many problems in the use of this kind of biomass stove: firstly, the energy cannot be fully utilized. After the biomass fuel is burned, it is directly discharged into the atmosphere through flue gas, and a large part of the preheating is wasted; secondly, due to the unreasonable structural design, The air supply is insufficient, the biomass fuel c...

Problems solved by technology

There are many problems in the use of this kind of biomass stove: firstly, the energy cannot be fully utilized. After the biomass fuel is burned, it is directly discharged into the atmosphere through flue gas, and a large part of the preheating is wasted; secondly, due to the unreasonable structural design, Insufficient air supply, biomass fuel cannot be fully burned, more residual carbon remains in the ashes at the bottom of the chamber, and the thermal efficiency of biomass cookers is low
