Abstract
A vertical civil heating stove with thorough fuel combustion is disclosed by the utility model, which belongs to the field of boiler technology and aims to overcome the defect of incomplete fuel combustion in prior vertical heating stoves. The vertical civil heating stove comprises a hearth, an internal water jacket and an external water jacket etc., wherein the upper part of the external water jacket and the internal water jacket form an annular flue; the lower part of the external water jacket surrounds the hearth. The improvements lie in that the upper part of the hearth is designed into an arch shape; the top part of the arch has a smoke outlet; the inner wall surface of the external water jacket corresponding to the arch top protrudes inward to form a local annular shrink mouth. While the utility model is in use, high-temperature flue gas can return to the hearth under the reflex action of the arch top, so the high-temperature heat energy is taken full use of; an additional refractory layer can prevent the hearth temperature decrease caused by heat absorption of the external water jacket and protect the inner wall of the external water jacket against corrosion by hazardous gases or oxidation by high temperature; an additional secondary air inlet passage strengthens the oxygen supply to the hearth for combustion. Therefore, the utility model has a plurality of advantages including thorough fuel combustion, high stove temperature, fast temperature rise, excellent heat efficiency as well as freedom of black smoke exhaust etc., and is applicable to vertical boilers, in particular, vertical civil heating stoves.
Description
Technical field
The utility model relates to vertical boiler, and especially the civil heating boiler belongs to the boiler technology field.
Background technology
Vertical civil heating stove has burner hearth, inside and outside water jacket etc., and outer water jacket is to form annular flue between tubular, top and the inner water sleeve, bottom double as burner hearth, and inside and outside water jacket is connected.This kind vertical boiler in use, the high-temperature flue gas that burner hearth burning produces directly is disposed in the atmosphere by flue, wastes a large amount of heat energy, fire box temperature is not easy to reach due high temperature; In addition, outer water jacket heat absorption capacity is bigger, takes away a large amount of heats easily, also is that fire box temperature is difficult to raise the inadequate factor of fuel combustion.Existing vertical civil heating furnace thermal efficiency is low, power consumption is high, also discharge black smoke frequently, must be improved.
Summary of the invention
Technical problem to be solved in the utility model be overcome above-mentioned defective and provide a kind of can clean-burning vertical civil heating stove.
The alleged problem of the utility model realizes with following technical solution:
A kind of can clean-burning vertical civil heating stove, burner hearth, inside and outside water jacket are arranged in the formation, outer water jacket top and inner water sleeve form annular flue, the bottom forms around the shape burner hearth, its improvement is, the top of described burner hearth 1 is arch, exhaust opening 5 is left at the arch top, and the internal face at described outer water jacket 3 corresponding arch tops convexes to form part annular reducing 6.
Above-mentioned can clean-burning vertical civil heating boiler, the part annular reducing 6 on the described outer water jacket is to being provided with flame retardant coating 1-1 between the bottom, flame retardant coating top should be arch mutually.
Above-mentioned can clean-burning vertical civil heating boiler, between water jacket 3 and the flame retardant coating 1-1 secondary air passage 7 is set outside described, the air inlet 7-1 of secondary air passage lower end communicates with the air inlet 12 of burner hearth bottom, the exhaust outlet 7-2 of upper end is positioned on the hole wall of exhaust opening 5.
Above-mentioned can clean-burning vertical civil heating stove, the quantity of described secondary air passage 7 is 3, evenly distributes, its cross section is a rectangle.
Above-mentioned can clean-burning vertical civil heating stove, the aperture of the dome height of described burner hearth 1 and described exhaust opening 5 is respectively 2/5～3/5 of furnace diameter.
The utlity model has following characteristics:
1. after adopting the arched hearth design, the high-temperature flue gas of burner hearth burning is subjected to getting back to again in the burner hearth after the reflection at arch top when rising, and high temperature heat is fully used; A large amount of gaseous volatilization branches that fuel was produced in the first stage of burning are fully burned because of reflection;
2. after the reducing of water jacket annular is set up flame retardant coating to the bottom outside, can prevent to reduce fire box temperature, simultaneously, can make outer water jacket internal face exempt from the erosion and the high-temperature oxydation of pernicious gas because of outer water jacket excessively absorbs heat;
3. the secondary air passage that is provided with between water jacket and the flame retardant coating outside strengthens the oxygen supply in the burner hearth combustion process, and makes air intake through pre-thermosetting hot blast and directly enter high temperature combustion zone, forms strong combustion-supportingly, burner hearth is rapidly heated and is incubated;
To sum up, the utlity model has sufficient combustion, burner hearth quick heating, furnace temperature height, thermal efficiency height, do not discharge multiple advantages such as black smoke, suit on the especially vertical civil heating stove of vertical boiler, to adopt.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 figure is an A-A profile in 1.
The specific embodiment
Consult Fig. 1, in the diagram, 1 is that burner hearth, 2 is that inner water sleeve, 3 is outer water jacket, and outer water jacket bottom forms the flue 4 of annular around burner hearth between top and the inner water sleeve.3-2 is the hot water outlet of outer water jacket top, 3-1 is the coolant intake of outer water jacket below, also be provided with heat exchanger tube 8 in the outer water jacket 3, its top is mounted with boiler 9, heat exchanger tube is coiled in the annular compartment of outer water jacket, the air inlet 12 of burner hearth is arranged on fire grate 13 belows, and exhanst gas outlet 10 is arranged on the boiler center.Boiler is provided with water nozzle, and drinking water can be provided; The entery and delivery port of heat exchanger tube 8 is connected with running water, shower head respectively, and shower hot water can be provided; Realize multi-use, can bring into play the thermal efficiency of heating stove to greatest extent.14 is cleaning door among the figure, and 15 is coal filling hole.
Consult Fig. 1,2, main improvement of the present utility model is, with burner hearth 1 upper design is arch, the exhaust opening 5 less than furnace diameter is left at the arch top, the corresponding inwardly protruding of internal face of outer water jacket 3 corresponding arch top portion, form part annular reducing 6, part annular reducing 6 is to being provided with flame retardant coating 1-1 between the bottom, and this flame retardant coating can be the refractory cement layer.The internal face on outer water jacket top can directly be processed into arch, also can form the top of arch by flame retardant coating.The bonding back, bottom surface of arch flame retardant coating 1-1 top and annular reducing 6 forms the exhaust opening 5 of one, and the aperture of dome height, exhaust opening 5 is respectively 2/5～3/5 of furnace diameter.
Another improvement of the present utility model is, be provided with several secondary air passages 7 outside between water jacket 3 and the flame retardant coating 1-1 at interval, the top of each air intake passage should be arch mutually, and the air inlet 7-1 of air intake passage communicates with the air inlet 12 of burner hearth bottom, exhaust outlet 7-2 is positioned on the hole wall of exhaust opening 5.The secondary air that provides directly enters the high temperature combustion zone of burner hearth after preheating.In the illustrated example, the quantity of secondary air passage 7 is 3, evenly distributes, and its cross section is a rectangle, is convenient to combine with outer water sleeve hearth wall, certainly, also can be other shape.
