Multi-fuel energy saving and emission reduction heating stove

Abstract

The invention discloses a multi-fuel energy-saving and emission reduction heating cooking stove, and aims to solve the problem that a heating cooking stove in the prior art cannot burn both biomass and coal. The multi-fuel energy-saving and emission reduction heating cooking stove is characterized in that a feed inlet is formed in the upper end of a combustion chamber; the bottom surface of the combustion chamber is a sliding grate; a first fire outlet, a second fire outlet and a third fire outlet are formed in the side wall, close to a flame path, of the combustion chamber; a stove wall water jacket is arranged on the inner side of a stove wall; a combustion chamber water jacket is arranged on the circumferential side of the combustion chamber; a cooking bench is arranged right above the combustion chamber; the flame path is provided with a kang hole; the stove wall water jacket and the combustion chamber water jacket are connected with heating water pipes; flame guide devices are arranged between the combustion chamber and the flame path; and a kang and chimney change-over switch is arranged at the connection part of the kang hole and a chimney. According to the multi-fuel energy-saving and emission reduction heating cooking stove, multiple purposes can be achieved through the stove, both biomass and coal can be burnt, strong force naturally circulates, the thermal efficiency is high, energy conservation and emission reduction are achieved, and promotion and popularization of renewable new energy resources like biomass are facilitated.

Description

technical field

[0001] The invention belongs to the field of stoves, in particular to a multi-fuel energy-saving and emission-reducing heating stove. Background technique

[0002] Most of the warm cooking stoves used by people adopt coal as fuel, and the biomass fuel is burned in coal stoves, which has a lot of smoke, tar, pollutes the air, and has low thermal efficiency. But the vast rural areas are still burning straw, polluting the air and wasting energy. Still use coal for heating and cooking, which makes the primary energy more scarce and aggravates the pollution of the environment. At present, the country vigorously advocates energy conservation and emission reduction and the use of biomass renewable new energy. The fuel that replaces coal is particularly prominent with biomass fuel made of straw, twigs, wood, wood flour, and corncobs. However, during the transition period, user families may The lack of either biomass fuel or stoves makes the promotion and populariza...
