Abstract

The invention provides a water-fire tube gas-steam boiler with a built-in condenser, and relates to a gas-steam boiler. An existing smoke-fire tube steam boiler has the problems that the structure occupies large floor area, potential safety hazards exist in the operation process, and steel consumption is high in the using process. The water-fire tube gas-steam boiler comprises a combustor, a steam tube base, a shell, a boiler furnace, a smoke tube assembly, a backdraft chamber, a condensation chamber and a smoke box; the boiler furnace, the smoke tube assembly, the backdraft chamber and the condensation chamber are all arranged in the shell, the combustor is arranged outside the shell and communicates with an inlet of the boiler furnace, an outlet of the boiler furnace communicates with an inlet of the backdraft chamber, an outlet of the backdraft chamber communicates with an inlet of the smoke tube assembly, an outlet of the smoke tube assembly communicates with an inlet of the condensation chamber, the smoke box is arranged outside the shell and communicates with an outlet of the condensation chamber, a smoke outlet is formed in the smoke box, multiple convection banks are arranged in the boiler furnace, condensation tube bundles are arranged in the condensation chamber, and the shell communicates with the steam pipe tube base. The water-fire tube gas-steam boiler is used for generating steam.

Description

technical field [0001] The invention specifically relates to a water-fire tube gas-fired steam boiler with a built-in condenser. Background technique [0002] Gas-fired steam boiler is a thermal energy conversion device that uses natural gas, liquefied petroleum gas, city gas, coke oven gas and other combustible gases as fuel, uses the heat released by the combustion of fuel in the furnace, heats the feed water entering the boiler, and vaporizes the water into steam. The water vapor output by the boiler is a form of secondary energy, which is widely used in various occasions that require steam in industry and life. [0003] There are many types of gas-fired steam boilers. Most of the large-scale steam boilers above 20t / h are water-tube boilers, such as D-type, O-type, box-type, etc. The furnace type of small and medium-sized gas-fired boilers below 20t / h is mainly internal combustion fire-tube boilers, among which the small-scale gas-fired boilers below 2t / h are mainly vert...
