Abstract

The invention discloses a burner and a gas water heater. The burner comprises at least one first fire grate and at least one second fire grate which are arranged in parallel. Each first fire grate comprises a fire spraying portion and an ejector, the fire spraying portion is in connection with the ejector, the fire spraying portion comprises a cavity with an opening on one face and a combustion panel arranged at the opening, the ejector comprises a connecting plate and at least two first ejector tubes arranged on the connecting plate, and at least two first ejector tubes are communicated withthe cavity. Each second fire grate comprises a second ejector tube, an airflow channel is formed in the second ejector tube, one end of the second ejector tube is an air inlet communicated with the airflow channel, the other end of the second ejector tube is an air outlet communicated with the airflow channel, and a plurality of fire outlet holes communicated with the airflow channel are formed inthe air outlet. The burner has the beneficial effects of facilitating the solving of the problems that a heat load and a nitrogen oxide emission rate of the burner are mutually restricted and are difficult to improve at the same time.

Description

technical field [0001] The invention relates to the technical field of gas appliances, in particular to a burner and a gas water heater. Background technique [0002] At present, civil burners have been widely used in various households, such as gas stoves, wall-hung boilers and other household products. The existing wall-hung boiler is a household device that uses gas as the main energy source to provide warm and comfortable home heating and domestic hot water. , Wall-hung boiler heating has a powerful central heating system, which can meet the requirements of multi-bedrooms, and wall-hung boilers are becoming a necessary equipment for Chinese families. [0003] As we all know, the burner in the wall-hung boiler is a key component related to the performance and efficiency of the wall-hung boiler, and the heat load and nitrogen oxide emission rate are important parameters to measure the performance of the burner. Existing burners will also have lower heat loads as they redu...
