Problems solved by technology

It utilizes the heat exchange between flue gas and air to utilize the heat into the intake air to heat the intake air and improve the thermal efficiency. However, this kind of gas heat exchange has high requirements on the heat exchanger, and the actual heat exchange effect is not that good. not ideal

Abstract

The invention provides a gas stove waste heat recycling method. The method comprises the following steps that (1), a combustor assembly is established, specifically, the combustor assembly comprises a combustor and a supporting ring, the combustor and the supporting ring can be integrated to a gas stove, the bottom of the combustor is provided with an air outlet, and thus a combustion area for igniting the gas-air mixed gas is formed; (2), two different heat exchangers are established so that heat exchange medium fluid can pass through the two heat exchanger assemblies in sequence, and heat recovery of the heat exchange fluid is achieved twice; (3), a connection control pipeline assembly is arranged, the flowing path of the heat exchange medium fluid is controlled through two three-way control valves, and the fluid can selectively pass through or not pass through one or two of the above two heat exchangers. By means of the method, multi-grade adjustment of heat recycling is performed according to actual requirements, and energy conservation performance of the gas stove in use is improved. Meanwhile, the invention furthermore discloses a gas stove waste heat recycling device applying the method.

Description

technical field [0001] The invention relates to a waste heat recovery method and device of a gas stove, belonging to the technical field of kitchen utensils. Background technique [0002] According to statistics, the existing gas stoves in the catering industry have serious heat loss and empty burning phenomenon is common. The average thermal efficiency is only 20%, and the heat loss is as high as 80%, resulting in great energy waste. The so-called thermal efficiency of the gas stove, in layman's terms, is the effective utilization rate of the gas heat energy during the use of the gas stove. As can be seen from the thermal efficiency of gas cookers, household gas cookers generally have a low utilization rate of gas heat energy, and about 40% to 50% of gas heat energy is wasted in use. The combustion method of the commercial gas stoves currently used in the market still adopts the traditional positive pressure open combustion method. During the gas combustion process, the co...
