Vertical biomass gas dual-purpose atmospheric-pressure hot water boiler

Abstract

The invention relates to a vertical biomass gas dual-purpose atmospheric-pressure hot water boiler. The vertical biomass gas dual-purpose atmospheric-pressure hot water boiler is composed of a boilershell, an annular water chamber, a combustion chamber, a flue and a drawer-type dust hopper; a water inlet pipe seat, a water outlet pipe seat and an atmospheric communicating pipe seat are arranged on the boiler shell, the drawer-type dust hopper is arranged at the bottom of the boiler shell, a feeding machine connector is formed in one side of the combustion chamber, a sewage-discharging pipe seat is arranged at the bottom of the annular water chamber, the flue is formed in the annular water chamber and comprises a main flue, a two-return-stroke flue and a three-return-stroke flue, the bottom end of the main flue is connected with the combustion chamber, the top end of the main flue communicates with the two-return-stroke flue through a first smoke chamber, the two-return-stroke flue communicates with the three-return-stroke flue through a second smoke chamber, a third smoke chamber is formed in the top end of the three-return-stroke flue, the third smoke chamber communicates with the exterior through a smoke vent, and a detachable pot-cover-shaped partition cover is arranged between the first smoke chamber and the third smoke chamber. The vertical biomass gas dual-purpose atmospheric-pressure hot water boiler has the beneficial effects that (1) the three-return-stroke flue is adopted, thus the smoke travel is increased, the heat exchange time of smoke and water is prolonged,the heat efficiency of the boiler is improved advantageously, the smoke discharging temperature is decreased, and the advantages of high heat efficiency, low smoke discharging temperature and low dust content are achieved; and (2) the detachable pot-cover-shaped partition cover is arranged, on the one hand, the first smoke chamber and the third smoke chamber can be separated, the complete flue isformed, on the other hand, the partition cover can be detached, thus dust in the flue is conveniently cleared, and maintenance is convenient.

Description

technical field [0001] The invention relates to a vertical biomass gas dual-purpose atmospheric pressure hot water boiler, which belongs to the field of heating equipment. Background technique [0002] Atmospheric pressure hot water boilers are divided into two categories: vertical atmospheric pressure hot water boilers and horizontal atmospheric pressure hot water boilers. Among them, vertical atmospheric pressure hot water boilers have the advantages of compact design, small space occupation, convenient installation and transportation, and relatively low price. Cheap and other advantages, widely used. However, the structure design of the traditional vertical atmospheric boiler is relatively simple, the flue gas flow is simple, the heating surface is small, the thermal efficiency is low, the flue gas emission is not up to standard, causing air pollution, and the application is limited. [0003] The fuel of the vertical atmospheric hot water boiler is gas, coal, biomass fue...
