Title:
INTEGRATED PRESSURE-BEARING CONDENSATION BOILER
Document Type and Number:
WIPO Patent Application WO/2022/160663
Kind Code:
A1
Abstract:
An integrated pressure-bearing condensation boiler, which relates to the technical field of boilers. The integrated pressure-bearing condensation boiler comprises a pressure-bearing housing (10), a heat-exchange boiler furnace (20) arranged in the pressure-bearing housing (10), a combustion chamber (30) in communication with the heat-exchange boiler furnace (20), and a cooling pipe group fixed in the heat-exchange boiler furnace (20). The pressure-bearing housing (10) is provided with a smoke discharge pipe (32), a heat-exchange medium inlet (11) and a heat-exchange medium outlet (12), which are in communication with the heat-exchange boiler furnace (20); and a heat-exchange medium circulates in the pressure-bearing housing (10) and the cooling pipe group from bottom to top, and performs counterflow heat-exchange with smoke gas moving in the heat-exchange boiler furnace (20) from top to bottom. The heat-exchange boiler furnace (20) comprises multiple levels of cylindrical heat-exchange chambers, wherein adjacent heat-exchange chambers are in communication by means of a smoke transfer channel; and the multiple levels of heat-exchange chambers are sequentially and repeatedly arranged from top to bottom according to a diffusion form by which high-temperature smoke gas diffuses from the middle to the periphery and then gathers from the periphery to the middle. By means of the cooperation of the pressure-bearing housing (10), the heat-exchange boiler furnace (20), the combustion chamber (30) and the cooling pipe group, the heat-exchange efficiency can be improved; and the structure is simple, and the manufacturing, installation and application costs are relatively low.
