Description

Built-in fume tube type heat pipe boiler

Technical field

The utility model relates to a kind of boiler plant.

Prior art

The conventional boiler device, though the boiler of built-in fume tube type is arranged, because it mainly relies on the heat conduction of heat radiation and boiler material to carry out exchange heat, fuel combustion institute liberated heat, have only part to pass to heated medium, a sizable part is still taken away by flue gas, has slatterned, and makes the thermal efficiency of boiler lower.Utilize heat pipe to conduct heat in boiler though at present have, major part is that the end with heat pipe places in the combustion chamber, makes flame directly heat heat pipe, makes the heat pipe heating temperature too high like this, and heat pipe explodes easily, has an accident.And the boiler of this use heat pipe has only adopted these fast characteristics of adopting heat pipes for heat transfer often, does not make full use of the means of various raising boiler thermal outputs, makes the thermal efficiency of boiler still undesirable.Because the thermal efficiency of boiler is lower, its volume is often bigger, and rolled steel dosage is big, and maintenance cost is also higher.

The utility model content

The purpose of this utility model is a kind of built-in fume tube type heat pipe boiler of design, to improve the thermal efficiency of boiler, reduces the volume of boiler, saves steel.

Technology contents of the present utility model is to realize like this, a kind of built-in fume tube type heat pipe boiler, constitute by fire door, combustion chamber and the flue above the combustion chamber and water inlet, delivery port, its special character is, (1) flue collector passes flue, its front end and preceding flue are connected, and its rear end and rear pass are connected, and delivery port is arranged on the flue.(2) heat pipe is installed in flue, an end of heat pipe is in rear pass.(3) have preheater above flue, pre-heating flue is housed in preheater, the front end and the preceding flue of pre-heating flue are connected, and preheater is connected by pipe with flue, and water inlet is arranged on preheater.(4) heat pipe is installed in preheater, an end of heat pipe is in preceding flue.

In above-mentioned technical solution, its special character is that also (1) flue inner chamber is divided into several regions by dividing plate, and each zone is connected one by one.(2) the preheater inner chamber is separated into 2 linking areas by dividing plate.

Usefulness of the present utility model is that (1) owing to adopted built-in smoke pipe, smoke pipe passes through from flue inside, has increased the heating surface area of heated medium, can make effective heating surface (area) (HS increase about 40%, helps improving the thermal efficiency of boiler.(2) in the heating surface area that increases heated medium, owing to adopted heat pipe, make the speed of heat conduction faster, more help improving the thermal efficiency of boiler.(3) owing to adopted preheater, heat in advance before can making heated medium enter flue, and in preheater, also adopted heat pipe, for the heat that more makes full use of in the flue gas has been created condition, can further improve the thermal efficiency of boiler.(4) because the utility model has adopted the method for the multiple raising thermal efficiency, under the ambient condition of heating as much, can make the volume of boiler littler, reduce the used steel of boiler.
