Energy saving and emission reduction gas stove

Abstract

The invention discloses an energy saving and emission reduction gas stove. The energy saving and emission reduction gas stove is matched with a pot body to form closed burning structure design, a burning device comprises a furnace body, a burning disc, a heat collection bearing ring, an ignition device and a combustion fan communicated with the bottom of the furnace body, and the combustion fan can effectively promote gas sufficient burning and improve the combustion efficiency; the heat collection bearing ring is in contact with a pot bottom so that the supporting effect on the pot bottom can be achieved; the transverse radiation direction of a flame can be changed so that longitudinal backflow and reutilization can be sequentially carried out, the good energy saving and emission reduction effects are achieved, and the heat using rate is greatly improved while gas is burnt again; meanwhile, after flameout, disappearing of heat on the burning disc and the heat collection bearing ring can be greatly retarded, and the good heat preservation effect is achieved; meanwhile, a waste heat conversion device greatly absorbs and uses high temperature waste gas heat, and the energy saving and emission reduction aims are effectively achieved; and the beneficial effects of guaranteeing indoor health and sanitation and being high in applicability are achieved, and the energy saving and emission reduction gas stove is suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of gas combustion stoves, in particular to an energy-saving and emission-reducing gas stove. Background technique [0002] Existing combustion methods for gas stoves used in homes and catering places are generally open-ended combustion, that is, the combustion disc is exposed, and the flame is in direct contact with the surrounding air during combustion, without any enclosure structure and heat recovery device. The most prominent shortcoming of this combustion method is that the heat loss is large, and trace it to its cause: the one, because be open combustion, the radiation of flame has only a part to be absorbed by the cooking pot bottom, and all the other are radiated in the environment; The heat is transferred to the cooking pot in the form of convective heat exchange with the flue gas, but the temperature of the flue gas leaving the pot is still high, and this part of the heat is wasted. [0003] The C...

Problems solved by technology

The invention has the characteristics of energy saving, emission reduction, health and safety, which improves the heat utilization rate and shortens the cooking time. Due to the isolation effect of the closed frying pan ring, the kitchen realizes zero emission of kitchen fume, which is safe for human health; But this technical solution still exists: 1) The closed frying pan ring makes the kitchen realize the zero emission of cooking fumes in the kitchen, but the high-temperature poisonous waste gas discharged from the gas pipeline is directly discharged to the outside, and these waste gases take away a large amount of heat without being used. 2) Although the closed space has improved a certain heat utilization rate and thermal insulation capacity, the package insulation structure added by the closed space is too large, takes up more space, and is not suitable for large pots. The use of low-end, and no combustion-supporting measures, the closed space makes it difficult for the gas to burn fully
