Pillow-shaped corrugated plate type spiral hot water boiler

Abstract

The pillow-shaped corrugated plate type spiral hot water boiler comprises a boiler shell and a heat exchange corrugated plate, the heat exchange corrugated plate is arranged in the boiler shell in a spiral mode, and therefore a spiral heating channel is formed in the boiler shell; the periphery of the heat exchange corrugated plate is closed, a hollow cavity is formed in the heat exchange corrugated plate, and a water inlet and a water outlet which are communicated with the hollow cavity are formed in the heat exchange corrugated plate. The boiler has the advantages that the heat exchange corrugated plate is spirally arranged in the boiler shell, cold water is introduced into the spiral heat exchange corrugated plate and enters the spiral heating channel through high-temperature flue gas for heat exchange, the heat exchange area is large, and the heat exchange efficiency is high; the boiler is compact in overall structure, small in size and high in heat exchange efficiency, hot water is available immediately after the boiler is opened, and the risk of boiler explosion cannot be caused by the adoption of the heat exchange corrugated plates.

Description

Technical field [0001] The present invention relates to the technical field of boiler equipment, specifically to a cushion-shaped corrugated plate type spiral hot water boiler. Background [0002] Hot water boilers include electric hot water boilers, oil-fired hot water boilers, gas hot water boilers and coal-fired hot water boilers, etc. Hot water boilers are boilers that produce hot water, which refers to a thermal energy equipment that uses thermal energy released by fuel combustion or other thermal energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. There are many types of existing hot water boilers, various varieties, but basically the boilers are mainly composed of pot barrels and steel pipe structures, the heating efficiency is low, the heat utilization rate is low, and a large amount of heat energy is wasted; in addition, the existing hot water boilers consider the cost problem, most of them use pressure hot water boilers, and ther...
