Abstract

The utility model discloses a steam boiler comprising a furnace body, a combustion chamber at bottom of the furnace body and a flue gas tube, which is communicated with the upper part of the furnace body. The furnace body is a water-jacketed furnace, which comprises an internal and an outer furnace body, while the flue gas tube is jacketed type comprising an internal and an outer flue gas tube. The Jacket of the flue gas tube is communicated with the water jacket of the furnace body while the air outlet pipe is communicated with both the upper flue gas tube and the indoor radiator. The utility model heats circulating water with combustion heat of the boiler by replacing water circulation of rational boiler with water vapor circulation. Therefore vapor produced by circulating water enters indoor radiator, which heats indoor air by heat of the vapor. Because to produce vapor by heating a spot of circulating water of the boiler is enough for steam boiler, the method is much faster compared with the speed of heating circulating water of whole boiler and radiator, at the same time, fast circulation of the vapor is capable of heating indoor air quickly. The utility model has characteristics of simple structure, small volume, small occupation area, excellent thermal efficiency, fuel saving, economic and environmental protection.

Description

Steam boiler

Affiliated technical field

The utility model relates to a kind of boiler, relates to a kind of steam boiler specifically.

Background technology

Most of area of China is all colder winter, so, all needing warming installation the winter of northern area basically. the big city warming adopts the mode of central heating mostly, can not adopt the place of central heating, uses boiler to drive the radiator heating mostly.Present boiler is coal-burning boiler basically, and by the recirculated water in the combustion heat heating boiler of fire coal, heated recirculated water reaches the purpose of heating by the radiators heat room air.In order to improve the thermal efficiency, reduce coal consumption, the structure of hot water space heating boiler is also being updated, boiler after the improvement, though the thermal efficiency obtains certain raising, also not fully up to expectations, in any case because change, hot water space heating boiler all needs the heating of the recirculated water in the interior radiator, and this just needs to consume a large amount of fire coals.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of steam boiler, and this boiler structure is simple, and cost is lower, fuel saving, and heating is fast, conducts heat rapidly, thermal efficiency height, use cost is low.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of steam boiler, comprise body of heater, this bottom of furnace body is the combustion chamber, be communicated with smoke pipe above the said body of heater, its structural feature is: said body of heater is the water-jacket typ body of heater that inner furnace body and external furnace body are formed, and the smoke pipe that said body of heater is installed above also is the jacket type smoke pipe of internal flue and outer smoke pipe composition, and the chuck of this smoke pipe is communicated with furnace water jacket, said smoke pipe top connects escape pipe, this escape pipe junction chamber inner radiator.

The stove inner water sleeve is installed in the body of heater of top, said combustion chamber, and this stove inner water sleeve is communicated with said furnace water jacket.

Said bottom of furnace body is provided with the return pipe that connects water tank and radiator.

Said upper of furnace body connects the safety valve pipe.

It below the said body of heater ashcan.

Connect condensate pipe below the escape pipe connection steam pipe at said smoke pipe top, this steam pipe junction chamber inner radiator, this radiator, this condensate pipe connects said bottom of furnace body.

The beneficial effects of the utility model are, the utility model changes the water circulation of conventional boiler into the aqueous vapor circulation, by the recirculated water in the combustion heat heating furnace body water jacket of fuel in the boiler furnace, the steam inlet chamber inner radiator that recirculated water is produced, interior radiator heats room air by the heat of steam, thereby reaches the heating purpose.Because steam boiler is as long as produce steam with a spot of recirculated water heating in the boiler, so more faster than the circulating water velocity in whole boiler of traditional heating and the radiator, simultaneously, the steam circulation is fast, heating room air that can be very fast.The utility model is through a whole set of improvement of boiler, water tank, radiator, what deliver to radiator is gas, what return is a spot of water, backwater transmits without boiler, naturally go back, warm oneself with this way, its heat, can be the twice of water circulation even three times, below half of its a coal consumption water circulation, the heating phase about 120 days, the coal consumption of water circulation is approximately all about the 5-7 ton, get off with heating phase of hot air heating, use less than 3 tons of coals (all referring to it is the area of 80 to 100 square meters).Owing to adopt the mode of steam boiler, do not have water in the pipeline or have only a spot of water, so, pipeline can not take place yet freeze phenomenon even do not use boiler.Normal winter, indoor temperature can arrive about the 18-20 degree, according to user's needs, regulates the different temperature in each room about subzero 15 degree, and backwater is easy for installation, uses any pipe all right, and can installation pipeline anhydrous, the time spent freeze yet.Boiler internal is only adorned the 5-6 kg of water, and boiler bottom is installed a water valve, conveniently water is put only.At China man cold district, use the heating of this form to can be a large amount of coal resources of country's saving.The utility model is simple in structure, and volume is little, and floor space is little, thermal efficiency height, and fuel saving, economic environmental protection has reduced use cost greatly.
