Abstract

The utility model relates to a gas boiler, which belongs to a heating device. The utility model comprises a boiler body and a boiler liner. The boiler liner is provided with a combustion chamber. A burner is arranged in the combustion chamber. The utility model is characterized in that a plurality of staggered water jackets are arranged in the boiler liner, and the staggered flues are arranged in the water jackets. The utility model has the advantages of large heating area, sufficient calorific energy absorption, high thermal efficiency, etc. The utility model can be widely used for heating in an institution, a plant, a school, a house of inhabitant, a building for business, etc.

Description

Gas fired-boiler

The utility model belongs to heating system, is a kind of improvement of gas fired-boiler.

Present gas fired-boiler is that ring-shaped water jacket is set in body of heater, is the through type flue in the middle of water jacket.The weak point of this boiler is that thermal waste is big, and the thermal efficiency is lower.

The purpose of this utility model is to provide a kind of can make full use of heat energy, gas fired-boiler that the thermal efficiency is high.

The purpose of this utility model is achieved in that this gas fired-boiler is by body of heater, flue, between body of heater and flue, be provided with heat-insulation layer, bottom at flue is provided with the combustion chamber, burner is set in the combustion chamber, top at flue is provided with upper hose, Pressure gauge and flue outlet, in the bottom of flue return pipe and blow-off pipe are set, its special character is: the staggered water jacket that is communicated with is set in flue, the top of water jacket and upper hose, Pressure gauge is communicated with, the bottom of water jacket and return pipe, blow-off pipe is communicated with, water jacket contains the staggered flue that is communicated with, and the top of flue is communicated with flue outlet, and the bottom of flue is communicated with composition with the combustion chamber.

Owing to adopt such scheme, the staggered flue that is communicated with of this gas fired-boiler is contained by the staggered water jacket that is communicated with, and has increased the heating surface area of water jacket, therefore, can fully absorb heat energy, has the high advantage of the thermal efficiency.Can be widely used in various buildings and one-storey house heat supply heatings such as office, factories and miness, school, residential building, commercial network.

Below in conjunction with drawings and Examples the utility model is further described.
