Abstract

The utility model discloses a highly effective environment protecting and energy saving hot-water boiler, designed aiming at the shortcomings of the coal adding style of adding coal on the consequent air intake fire of the traditional boiler, which makes the temperature of the boiler rise slowly and produce black smoke, and not only affects the heating efficiency but also pollutes the environment. The utility model comprises a boiler base, a boiler body and a smoke tube, characterized in that both sides of the upper portion of the boiler base are equipped with a coal adding opening which is also a reverse air inlet and the stokers of the boiler are distributed obliquely from the outside to the bottom of the boiler base. A slag cleaning door is arranged on the upper portion of the boiler base which is higher than the stokers, and several exhaust pipes which are centrally and circumferentially distributed are arranged on the water chamber of the boiler body, and then the boiler leads to the chimney via the water-box. The utility model guarantees the continuous burning to keep raising the temperature of the boiler by changing the traditional air intake burning type, thereby saving energy resources without polluting the environment, achieving 85 percent of the heating efficiency with the Linkman blackness being less than 1, and being applicable to all aspects like drinking, heat supplying, shower and the like.

Description

The high-efficiency environment friendly energy-conservation hot-water boiler

Technical field: the utility model relates to a kind of hot-water boiler.

Background technology: its coal-adding type of traditional hot-water boiler is forward air intake coal-feeding on fire, be that air inlet is following, cold coal is pressed on the burning zone, Chinese patent ZL96221677.1 disclosed " vertical double water jacket burning boiler " for example, and its two combustion chambers are not always the case.The greatest drawback of this coal-adding type is exactly because cold coal absorb heat earlier afterwards generates heat, so make coal will produce a large amount of flue gases and fuel gas from the chimney discharge and over-emitting black exhaust in the endothermic pyrolysis process, this will reduce the thermal efficiency with just being difficult to be avoided and cause environmental pollution.

Summary of the invention:

Task of the present utility model is at above-mentioned defective, a kind of high-efficiency environment friendly energy-conservation hot-water boiler is provided, it guarantees the continuity of burning and then continues to improve furnace temperature by changing the rich mode of traditional air intake combustion, not only free from environmental pollution but also energy savings, and can improve the thermal efficiency of boiler greatly.

Technical solution of the present utility model is: a kind of high-efficiency environment friendly energy-conservation hot-water boiler, comprise the stove seat that is divided into the rich chamber of combustion and following ash chamber and ash hole by fire grate, the body of heater of forming by water jacket and smoke exhaust pipe etc. and chimney etc., it is characterized in that: the both sides on stove seat top are provided with stoking mouth, fire grate is tilted by export-oriented furnace bottom, be provided with breast hole on the stove seat top that is higher than fire grate, one group of smoke exhaust pipe is center and circle distribution.

In order to improve the thermal efficiency, this hot-water boiler stove seat is made as intercalated water sleeve and is connected with furnace water jacket.And be provided with the water bag on smoke exhaust pipe top and be connected with furnace water jacket.

Compared with prior art, the utlity model has following advantage:

(1) fire grate owing to it tilts to furnace bottom, coal filling hole is located at stove seat top, belongs to vertical coal, the reverse wind of giving, so can make cold coal outside in rich through entering combustion after the abundant preheating again, therefore not only guaranteed the rich continuity of combustion, made flame burn more prosperous and more prosperous, and under the effect of reverse air intake, can press to high temperature combustion zone to a large amount of fuel gas that cold coal decomposes in warm, so both combustion-supporting, be unlikely to contaminated environment again, both improved boiler thermal output, saved the energy again.

(2) owing to adopt at the stove seat and establish intercalated water sleeve and the technical measures of water bag are set on smoke exhaust pipe top, therefore the waste heat of boiler is fully utilized, the particularly setting of water bag has utilized the high temperature of outlet flue well, so has further improved the thermal efficiency of the present utility model.

(3) because one group of smoke exhaust pipe of employing makes boiler become wide water jacket design, therefore easily scale removal, blowdown is unobstructed, and the thickness pipe is heated in addition, thus can make each several part even water temperature fast rise, and heat supply temperature does not reduce.In addition, this equipment does not need any wind power apparatus of giving when operation, and fully by the natural air inlet burning, and a coal amount is big, and can reduce coal number of times, particularly coal does not influence burning, and slagging scorification can in time be removed.Benefits such as therefore it also has installation easily, and is simple to operate, and operating cost is low.

All things considered, the thermal efficiency of the present utility model can reach 85%, and woods can be overflow blackness＜1, reaches relative national standards fully, is suitable for large scale application.

Description of drawings:

Fig. 1 is a structural representation sketch of the present utility model, analyses and observe along Fig. 2 B-B.

Fig. 2 is that the A-A of Fig. 1 cuts open vertical view.

The specific embodiment: as shown in the figure, the hot-water boiler that the utility model provides is made of stove seat, body of heater, chimney etc., stove seat 1 wherein is connected for intercalated water sleeve and with furnace water jacket 4, stove seat 1 outside is provided with water inlet and ash hole and breast hole etc., inside is provided with the fire grate 8 by export-oriented furnace bottom inclination, fire grate 8 tops are the rich chambers of combustion, and the bottom is an ash chamber, and the both sides above the stove seat 1 are provided with stoking mouth 2 that is air inlet; Body of heater outside wherein is provided with delivery port, thermometer etc., inside comprises water jacket 4 and flue, and its flue is made up of one group of smoke exhaust pipe 5, and smoke exhaust pipe 5 is center and circle distribution, body of heater 2 tops are provided with water bag 6 between flue and chimney 7, water bag 6 is connected with furnace water jacket 4.Here said ash hole 10 and breast hole 9 all are provided with the switch door, and said chimney bottom is provided with swinging switch baffle plate.

The utility model can be used for various aspects such as drinking-water, heating, bathing.
