Efficient energy-saving gas boiler

Abstract

The invention discloses an efficient energy-saving gas boiler which comprises a boiler shell, a fire inlet, a smoke outlet, a water return opening and a water outlet. The fire inlet is arranged at theupper end of the right side surface of the boiler shell, the smoke outlet is arranged at the lower end of the left side surface of the boiler shell, the water return opening is arranged at the lowerend of the boiler shell, the water outlet is arranged at the upper end of the boiler shell, a water tank is arranged in the boiler shell, a plurality of rows of transverse metal pipelines are arrangedin parallel in the water tank, the two ends of the metal pipelines extend outwards to be 20-40 mm away from the water tank, the ends of the metal pipelines are connected through a communication assembly, the multiple metal pipelines are connected end to end through the communication assembly to form a unidirectional communicating metal pipeline, a gap between the outer wall of the water tank andthe communication assembly is filled with a heat insulation material, and the outer side between the communication assembly and the water tank and the outer side of the communication assembly are sealed by iron plates. By means of the technical scheme, the problems of low heat efficiency and the like of a traditional gas heating boiler are solved.

Description

technical field [0001] The invention belongs to the technical field of gas boilers, and in particular relates to a high-efficiency and energy-saving gas boiler. Background technique [0002] Traditional gas-fired heating boilers have roughly the same structure. There is a main furnace with horizontal heat-absorbing exhaust pipes in the furnace body. The furnace wall is double-layered and hollow, with a water jacket inside. There is an opening under the front of the furnace body for the inlet of the burner. When working, the burner is ignited, the flame grills the furnace wall, heats the water in the water jacket, and when it travels upwards to the chimney outlet, it passes through several layers of heat-absorbing exhaust pipes, and heats the exhaust pipes and the water in the exhaust pipes. This process is the heating of the burner. The water in the boiler, the water in the boiler is connected with the heating facility, and circulated by the water pump to achieve the purpos...
