Description

Energy-efficient civil boiler

The utility model relates to a kind of small-sized civil boiler.

The shortcoming of existing small-sized civil boiler is, fuel is when the boiler internal combustion, stove fire is not prosperous, this mainly is because the civil boiler inner water wall of existing structure causes coal and stops burning, coal can not well be burnt, also form the separation layer of dead coal, tobacco tar and water wall, influenced the heat exchanging process of stove fire and water.Because stove fire is not prosperous, flare is short, the speed of cooking also is affected.

The purpose of this utility model is intended to overcome the deficiency of prior art, and a kind of simple in structure, reasonable in design, combustion efficiency is good, the thermal efficiency is high energy-efficient civil boiler is provided.

The utility model comprises body of heater (1), flue (2), fire grate parts such as (3).Body of heater of the present utility model (1) and flue (2) are double sandwich hydroecium structure.Be connected to several upright convection tubes (4) in the flue week.The double sandwich hydroecium (6) of body of heater (1) is by being communicated with the double sandwich hydroecium (7) of flue (2) discharge orifice (5).Water inlet pipe (8), outlet pipe (9) are connected on respectively on body of heater (1) and the flue (2).Stove operator of the present utility model (3) is communicated with formation by ring-like pipe (10) and several transverse tube (11), and the top of ring-like pipe (10) and transverse tube (11) has fresh air inlet (12), and ring-like pipe (10) connects blast pipe (13).Inside and outside pre-burning cover (14), (15) with holes are housed respectively in the body of heater of the present utility model (1), ring-like flue cover (16) is housed on the flue (2).

The utility model is along being equipped with a ring-like steam pipe (17) in the flue (2), the inlet of this pipe (18) connects water tank, and outlet (19) is placed in the flue outlet.

Simple in structure, reasonable in design, characteristics such as combustion efficiency is good, thermal efficiency height that utility model has.

Fig. 2 is the utility model schematic top plan view;

Fig. 3 is the block diagram of the utility model flue cover, outer pre-burning cover.

Below in conjunction with accompanying drawing the technical solution of the utility model is further described:

As shown in Figure 1, 2, 3, the utility model comprises body of heater (1), flue (2), fire grate parts such as (3).The utility model adopts the A3 steel plate to make, and body of heater (1) and flue (2) are double sandwich hydroecium structure.Connect 10 week in the flue convection tube (4) is arranged.The double sandwich hydroecium (6) of body of heater (1) is by being communicated with the double sandwich hydroecium (7) of flue (2) discharge orifice (5) of equidistantly distributing, and it plays the effect that makes the directed discharging of hot water in the body of heater, also directly acts on 10 convection tubes (4) in the flue, is heated by force.Water inlet pipe (8), outlet pipe (9) are connected on respectively on body of heater (1) and the flue (2).The other end of water inlet pipe (8) is connected on the water return pipeline of radiator, and the other end of outlet pipe (9) is connected on the watering pipeline of radiator.Fire grate of the present utility model (3) is communicated with formation by ring-like pipe (10) and 9 transverse tubes (11), and the top of ring-like pipe (10) and transverse tube (11) has fresh air inlet (12) equably, and ring-like pipe (10) connects blast pipe (13).Air blast is blown in hollow fire grate by blast pipe (13), and the fresh air inlet (12) that passes through on ring-like pipe (10) and the transverse tube (11) is blown to burner hearth, make the fuel in the burner hearth that sufficient comburant oxygen be arranged, improved efficiency of combustion greatly, reduced because of anoxic, the insufficient black smoke that produces of burning.Inside and outside pre-burning cover (14), (15) with holes are housed respectively in the utility model body of heater (1).On fire grate (3), the loam cake of interior pre-burning cover (14) is demountable to interior pre-burning cover (14) by four means of spot welds.Outer pre-burning cover (15) is outer to be welded with heat conduction wing plate (20), and this heat conduction wing plate directly contacts with inboard wall of furnace body, transmits heat.Outer pre-burning cover (15) also makes fuel and body of heater inner water wall isolate, and has stopped the possibility of the long-term burning of fuel at body of heater inner water wall generation separation layer.Therefore, the utility model adopts the structural design of inside and outside pre-burning cover, both impelled in the body of heater fuel as early as possible, burning up hill and dale, obtain the effect that improves furnace temperature, by the smooth heat conduction of the heat conduction wing plate (20) of outer preheating cover (15), combustion efficiency is improved greatly again.In addition, when initial igniting, light in the preheating cover (14) in ignition substance can also being placed on and ignite.In addition, the utility model is along a ring-like steam pipe (17) is housed in the flue (2), the inlet of this pipe (18) connects water tank, outlet (19) is placed in the flue outlet, under the situation of control discharge, water tank water constantly enters ring-like steam pipe (17), because the heat effect of furnace temperature in the flue, make the water in the steam pipe all heat vaporization, this water vapour is entered in the flue outlet by outlet (19), the still unburnt fuel that is entered flue outlet by body of heater is done fire extinguishing handle, avoid the unburnt Mars flue that flies out, cause the possibility of fire.

Use the utility model can make coal fully, burning up hill and dale.Behind a fire coal, it is quite fast to heat up in the stove, the stove fire seedling was climbed at 5 minutes to 8 minutes and is reached the top, faster than general miniature boiler, as seen coal is the make progress thermal efficiency of ascension of blue yellow flare all around along outer pre-burning cover about 10 minutes in the stove, the water temperature of boiler at this moment can reach 70 degree, and formation hot and cold water Natural Circulation state, be general civil boiler the thermal efficiency 1-2 doubly, stove fire after 10 minutes just can have been cooked in cooking, this usefulness of stove fire efficiently is 2-3 times of general boiler fire, if be equipped with air-introduced machine and air blast better effects if.When stove fire reached the most prosperous, when inserting new coal again, visible coal smoke obviously reduced, and coal smoke is with the rising of the temperature in the stove and sufficient air inlet is combustion-supporting has almost all burnt down.Stove fire need not, after breath went out naturally, the coal ash at wall and fire grate place was greyish white powdery in the visible stove.This boiler, ring shaped slot can be installed in the burner hearth lower end, and under the motionless situation of other parts, fuel such as the waste diesel that can burn, used oil, useless heavy oil are loaded onto suitable gas appliance, can also utilize the coal gas energy.
