Description

The fast energy-saving boiler for dual purpose

Technical field

The utility model relates to a kind of boiler plant, is specifically related to a kind of steam boiling water boiler for dual purpose, belongs to the boiler technology field.

Background technology

The chemical energy that the principle of the steam water boiler on domestic market is fuel is converted to heat energy by burning, then through diabatic process, the heat transmission is fed water, and makes water become boiling water and steam.But the following shortcoming of the equal ubiquity of existing equipment: 1, burning velocity is slow, by the combustion-supporting not only reduction furnace temperature of air blast and produce a large amount of tail gas, takes away amount of heat, waste fuel; 2, heat absorption speed is slow, and heat production water and steam efficiency are low.

The utility model content

The purpose of this utility model is for above-mentioned technical problem, proposes a kind of by improving EAT, rising furnace temperature, the steam boiling water boiler for dual purpose of increase heating surface area.

The utility model solves the problems of the technologies described above the technical scheme that adopts: the fast energy-saving boiler for dual purpose comprises shell, convection bank, burner hearth, flue, cooling water inlet, hot water outlet, steam (vapor) outlet, cooking stove and hot bellows; Described cooling water inlet, hot water outlet, steam (vapor) outlet are arranged on the shell outer wall; Described shell serves as water tank simultaneously, described burner hearth is arranged in the boiler center, by shell around, be furnished with some convection banks in described burner hearth, fuel washes away convection bank and shell inwall at the high-temperature flue gas that described cooking stove burning produces in burner hearth, heat is passed to cold water by heat exchange, produce hot water and steam; Described hot bellows has improved furnace temperature around the cooking stove setting when improving EAT, makes fuel combustion more abundant, reduces intake and exhaust emissions amount, has improved the efficiency of combustion of fuel, has saved fuel.

Better, be provided with a hot and cold water demarcation strip between described cooling water inlet and hot water outlet, described water tank is separated into hydrothermal area and cold water area, guarantee the constant temperature and pressure supply of hot water and steam.

Better, the edge of described hot and cold water demarcation strip is provided with circulation passage, rises to the hydrothermal area for the hot water that generates that is heated of cold water area, and hydrothermal area's lip temperature lower flow to cold water area under water.

Better, described convection bank and shell inwall are obliquely installed at an angle, have increased the heating surface area of convection bank, accelerated heat absorption speed, the temperature of cold water is raise fast, prevent that simultaneously the steam that generates in convection bank is trapped on tube wall, produces hot-spot.

Better, described convection bank comprises convection bank and lower convection bank, and described lower convection bank is arranged on the cold water area of described water tank, and cold water is subject to washing away of high-temperature flue gas in lower convection bank, absorb heat and become hot water; Described upper convection bank is arranged on the hydrothermal area of described water tank, the hot water intensification of further being heated in upper convection bank.

Better, the water pipe quantity of described upper convection bank is less than the water pipe quantity of lower convection bank, the lower tight water circulation that is beneficial to boiler that is furnished with of dredging that goes up.

The utility model has designed the hot bellows around cooking stove, improved the temperature of air intake, make fuel combustion more abundant when promoting furnace temperature, reduced the discharge capacity of tail gas, and then reduced the waste of energy, the convection bank that is obliquely installed has simultaneously increased heating surface area, has accelerated the thermal velocity that is subjected to of boiler, has improved the utilization rate of energy.
