A commercial gas stove

Abstract

Provided is an efficient and energy-saving commercial gas stove. An exhaust fume collecting hood, an air inlet pipeline and a burner are connected through a pipeline in the air inlet sequence. Heat exchangers are arranged in the air inlet pipeline and composed of the one-stage or two-stage or multi-stage front heat exchanger and the rear heat exchanger, or the length of heat exchange pipelines of the heat exchangers is not smaller than 400 mm. Cooking fume entering the air inlet pipeline is fully heated into cooking fume gas when passing through the heat exchangers, and then the cooking fume gas enters the burner to participate in combustion. According to the efficient and energy-saving commercial gas stove, the recovered cooking fume is subjected to secondary preheating or long-distance preheating before the cooking fume is heated and participates in combustion, the cooking fume participating in combustion is heated more easily and subjected to complete combustion, and the combustion performance of the cooking fume can be obviously improved. Meanwhile, the space of the air inlet pipeline is utilized, heat supply energy of the heat exchangers only comes from heat generated by combustion of the cooking fume gas, and first-level energy efficiency is broken through for the first time in gas stoves of 40 KW or above. Waste gas after combustion is exhausted after being cooled, and adverse factors caused by high-temperature exhausted waste gas are avoided.

Description

technical field [0001] The invention relates to an energy-saving cooker, in particular to a high-efficiency and energy-saving commercial gas cooker aimed at oil fume treatment technology. Background technique [0002] Gas stoves, especially Chinese-style gas stoves, produce a large amount of oil fume, and the oil fume itself can be used as a fuel. It is undoubtedly a waste to simply remove the oil fume. The technology of using oil fume as fuel has gradually attracted the attention of the industry. How to improve the utilization rate of oil fume and make better use of oil fume as fuel to save energy and improve the combustion effect will inevitably become one of the development directions of future stoves. [0003] The applicant found in the long-term improvement practice of cooking stoves that using a single heat exchanger with a short pipeline path for energy saving cannot fully exert the energy-saving effect of the cooking stove. In the lower season, the intake air is not...

Problems solved by technology

[0003] The applicant found in the long-term improvement practice of cooking stoves that using a single heat exchanger with a short pipeline path for energy saving cannot fully exert the energy-saving effect of the cooking stove. In the lower season, the intake air is not fully heated in a short period of time, which will cause the fuel participating in the combustion to be unable to fully decompose and burn
