Waste heat conversion integrated large stove

Abstract

The invention discloses a waste heat conversion integrated large stove including a stove body and an exhaust gas treatment device. The stove body includes a burner and a furnace which are connected, anatural exhaust channel and the exhaust gas treatment device are connected with the furnace, and a conversion guide valve is arranged between the natural exhaust channel and the exhaust gas treatmentdevice. The exhaust gas treatment device includes an exhaust gas exhaust pipe and a tap water heating pipe. The tap water heating pipe includes a tap water inlet pipe, a low temperature heat exchanger, an intermediate temperature heat exchanger, a high temperature heat exchanger and a heat water outlet pipe. The exhaust gas exhaust pipe includes a high-temperature exhaust gas channel, an intermediate connection box, a middle-low temperature heat exchange box, and a forced-discharge suction fan. A high-temperature heat channel penetrates the high-temperature heat exchanger, and the intermediate temperature heat exchanger is arranged in the middle-low temperature heat exchange box, and the low-temperature heat exchanger is wound around the middle-low temperature heat exchange box. Through arrangement of the conversion guide valve, a large amount of generated waste heat is used, and through arrangement of the exhaust gas exhaust pipe and the tap water heating pipe, the utilization of waste heat is improved, and the thermal pollution is reduced.

Description

technical field [0001] The invention relates to the field of waste heat recovery, in particular to a waste heat conversion integrated large cooker. 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 combustion f...
