Abstract

The invention provides a condensing gas wall-hanging stove and belongs to the technical field of gas appliances. The condensing gas wall-hanging stove solves the problems that an ordinary gas wall-hanging stove is low in thermal efficiency, loud in gas sound and the like. The condensing gas wall-hanging stove comprises a shell, a main heat exchanger, a gas inlet pipe, an air inlet pipe, a draught fan assembly, a condensing unit, a smoke exhaust pipe and a plate-type exchanger assembly. The air inlet pipe and the gas inlet pipe are both connected to a premixer, the premixer is arranged on an inlet of the draught fan assembly, the main heat exchanger comprises a stove core and a water duct formed in the outer wall of the stove core in an upward spiral mode, the draught fan assembly is connected to the top of the stove core, the condensing unit is arranged at the bottom of the stove core, and the plate-type exchanger assembly is connected with a water inlet and a water outlet of the water duct. Gas and air are mixed through the premixer on the inlet of the draught fan assembly and then blown into a combustion chamber in the stove core through a draught fan. The usage amount of gas can be automatically adjusted through a gas proportional valve so that the gas and the air are kept in the optimum combustion mixing ratio all the time, and optimum combustion conditions are achieved.

Description

technical field

[0001] The invention belongs to the technical field of gas appliances, and relates to a gas boiler, in particular to a condensing gas wall-hung boiler. Background technique

[0002] Condensing gas boilers, as the name implies, are condensing gas boilers. The current condensing gas boilers can be divided into condensing domestic gas boilers and condensing commercial gas boilers. The products can also be divided into two series: condensing floor-standing boilers and condensing wall-mounted boilers. The most important of the condensing gas wall-hung boilers is naturally the realization of condensation technology. The key of the condensing boiler lies in the condensation technology, which is a new type of energy-saving and environmentally friendly technology. Its principle is not complicated. A simple summary is to recover the heat energy in the flue gas by condensing the flue gas. In traditional boilers, the exhaust gas temperature is generally 160-250°C, or ev...
