Abstract

The invention discloses a premixing device for combustion heat exchange equipment and the combustion heat exchange equipment with the premixing device. The premixing device for the combustion heat exchange equipment comprises a cavity, the cavity is provided with a gas inlet, a fuel gas inlet and a mixed gas outlet, a plurality of mixed gas distribution holes are formed in a distribution plate, apremixing pipe is arranged on a gas mixing plate, at least part of an air inlet pipe is arranged in the premixing pipe in a sleeve mode, and a gap is formed between the air inlet pipe and the premixing pipe to form a fuel gas inlet channel. According to the embodiment of the premixing device for the combustion heat exchange equipment, when fuel gas is exhausted from the fuel gas inlet channel, airin the air inlet pipe generates impact force on the fuel gas, and the distribution plate can uniformly disperse fuel gas mixed gas, so that the mixed gas outlet is uniformly filled with the fuel gasmixed gas, and the mixed gas outlet is uniformly filled with the mixed gas, so that the high combustion efficiency of the fuel gas mixed gas during combustion can be guaranteed, and in addition, the matching structure of the air inlet pipe, the gas mixing plate and the distribution plate is simple.

Description

technical field [0001] The invention relates to the field of water heaters, in particular to a premixing device for combustion heat exchange equipment and the combustion heat exchange equipment provided therewith. Background technique [0002] Combustion heat exchange equipment (take gas water heater as an example) is a kind of equipment that heats cold water by burning gas. When the gas water heater is working, it will produce harmful substances (for example: NOx (nitrogen oxide pollutants), CO (carbon monoxide), etc.), among them, the temperature of the combustion zone, whether the temperature field is uniform, the peak temperature, and the gas mixture The residence time in the high-temperature zone and the air coefficient will both have an impact on the NOx emissions emitted by the gas water heater. As for the CO content in the flue gas after combustion, at a certain flame temperature, if there is sufficient oxygen and residence time, the CO The concentration will drop t...
