Abstract

The invention discloses a gas water heater provided with a cold water inlet pipe and a hot water outlet pipe. The gas water heater comprises a shell, a catalysis combustor, a preheating combustor anda heat exchanger. A combustion chamber is formed in the shell. The catalysis combustor is arranged in the combustion chamber. The preheating combustor is arranged in the combustion chamber and is adjacent to the catalysis combustor. When the preheating combustor conducts combustion, the preheating combustor acts on the catalysis combustor, and the catalysis combustor is heated. One end of the heatexchanger communicates with the cold water inlet pipe, and the other end of the heat exchanger communicates with the hot water outlet pipe. The heat exchanger is used for absorbing heat generated dueto combustion of the preheating combustor and combustion of the catalysis combustor and conducting heat exchange on the absorbed heat and water in the heat exchanger. The gas water heater is simple and compact in structure, the energy utilization rate can be sufficiently improved, and harmful substance emission is reduced.

Description

Technical field [0001] The invention relates to the technical field of combustion heat exchange, in particular to a gas water heater. Background technique [0002] At present, the structure of traditional gas water heaters is complicated, and the main combustion method adopted is flaming combustion, which is an oxidation reaction in which fuel and oxygen or air undergo rapid heat release and light emission and appear in the form of flame. This combustion method not only burns incompletely, has low heat exchange efficiency and low energy utilization, but also generates more pollutants during the combustion process, which is one of the main reasons for frequent haze weather. Summary of the invention [0003] The main purpose of the present invention is to propose a gas water heater, which aims to solve the technical problems of complicated structure, low energy utilization rate and easy generation of harmful substances in the prior art gas water heater. [0004] In order to achieve t...
