Combustion chamber structure for heat exchanger

Abstract

The invention relates to a combustion chamber structure for a heat exchanger. The combustion chamber structure comprises a combustion chamber, a combustion chamber cavity is formed in the combustion chamber, and a heat transfer medium passage is formed between positioning lug bosses on the outer wall of the combustion chamber; heat exchange fins are arranged in the combustion chamber; and the heat exchange fins are distributed from thin to thick between the top and the bottom of the combustion chamber. When the capacity of the combustion chamber is unchangeable, the combustion chamber structure increases the heat absorption area, shortens the propagation distance of the combustion flame, reduces the deflagration probability, reduces heat loss and improves the heat conversion efficiency; when the gas enters the combustion chamber cavity from the top of the combustion chamber, high cyclone movement is generated; when the gas just enters the combustion chamber, the speed of the gas is maximum speed; because of airflow movement, the flame propagation in a rapid combustion period is accelerated, the cooling of the mixed gas at the tail end is increased, combustion change between cycles is reduced, and the ignition boundary of the mixed gas is enlarged; the combustion chamber structure is favorable for combusting thinner mixed gas so that the combustion is more full, the generation of harmful gas such as carbon monoxide is reduced, and the fuel gas loss is reduced; and the combustion chamber structure is safe and reliable.

Description

technical field [0001] The invention relates to a combustion chamber, in particular to a combustion chamber structure for a heat exchanger, belonging to the technical field of heat exchangers. Background technique [0002] The role of the combustion chamber for heat exchangers is to convert the chemical energy of the combustion gas into heat energy with practical value, but the structural design of the combustion chamber directly affects the heat transfer efficiency of the heat exchanger, the combustion performance of the heat exchanger and safety. With the development of heat exchangers in the direction of high efficiency, energy saving, consumption reduction and environmental protection, the design of the combustion chamber is becoming more and more important. At present, the heat exchange efficiency of domestic heat exchangers is generally between 70% and 85%, and most of the combustion chambers are cylindrical, semi-spherical, etc., which cannot achieve the goal of high...
