Abstract

The utility model discloses a vertical steam boiler, including a furnace body, be equipped with a stove courage in the furnace body, be the water tank between the feng bi of furnace body and the outer wall of stove courage, the top of stove courage is connected with a combustor, the head of combustor has the thermal -insulated circle of one deck with the junction of furnace body, bottom and a base smoke box of stove courage are linked together, the base smoke box is linked together through one two return stroke tobacco pipe and the last smoke box of establishing at the furnace body top, first section exocoel of furnace body encloses and has a cooling jacket, the bottom of cooling jacket's top and thermal -insulated circle is flat mutually, establishes a cooling jacket through adding, getting into cold water before the water tank cooling jacket that flows through earlier, on the one hand to effectively dispelling the heat on the top of stove courage improvement boiler inner chamber steam space to improve specified steam volume, and reduce the moisture content content in the steam, simultaneously, cold water is through laggard the incomes water tank of cooling jacket heating, improves the combustion efficiency of boiler, practices thrift the energy of preciousness.

Description

A kind of vertical steam boiler
Technical field
The utility model relates to a kind of steam boiler, relates to specifically a kind ofly can ensure the rated capacity of boiler and the vertical steam boiler of steam quality.
Background technology
As shown in Figure 2, existing vertical steam boiler generally includes the vertical flue in a body of heater and body of heater, and vertical flue joins overhead burner, and flue top inner chamber builds fire clay, and the combustion head of burner stretches into flue top.Be provided with a base smoke box in the bottom of flue, base smoke box is connected with the upper smoke box being located at body of heater top by a two return smoke pipe.When the vertical steam boiler of this structure works, flue top relies on the fire clay of interior block overheated to prevent completely, causes the vertical boiler inner chamber vapor space of this structure to be restricted (its vapor space height just equals the height that flue top inner chamber builds fire clay).Because the boiler intracavity vapor space is little, cause rated capacity little, and usually water entrained by steam.
Summary of the invention
For overcoming above-mentioned defect, the utility model aims to provide and a kind ofly can greatly improve the vertical steam boiler that in rated capacity, steam, moisture content is lower.
For achieving the above object, the technical solution adopted in the utility model is: a kind of vertical steam boiler, comprise a body of heater, a flue is provided with in described body of heater, it is water tank between the wind wall of body of heater and the outer wall of flue, the top of described flue is connected with a burner, the head of described burner and the junction of body of heater have one deck insulating collar, the bottom of described flue is connected with a base smoke box, described base smoke box is connected with the upper smoke box being located at body of heater top by a two return smoke pipe, the exocoel of the upper semisection of described body of heater is with a cooling jacket, the top of described cooling jacket is equal with the bottom of insulating collar, the top of described cooling jacket is respectively equipped with a water inlet and a delivery port, described water inlet is connected with water supply system, described delivery port is connected with water tank.
Have employed vertical steam boiler of the present utility model, by adding a cooling jacket, first flowing through cooling jacket entering the cold water before water tank, on the one hand efficiently radiates heat being carried out to the top of flue, improve the boiler intracavity vapor space, thus improve nominal steam amount, and the water content reduced in steam, meanwhile, cold water enters water tank after cooling jacket heating, improve the efficiency of combustion of boiler, save the valuable energy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of existing vertical steam boiler.
In figure: 1-body of heater, 2-flue, 3-burner, 4-base smoke box, 5-two return smoke pipe, 6-upper smoke box, 7-cooling jacket, 8-water inlet, 9-delivery port, 10-water tank, 11-horn mouth, 12-insulating collar.
Detailed description of the invention
As shown in Figure 1, the utility model discloses a kind of vertical steam boiler, comprise a body of heater 1, a flue 2 is provided with in described body of heater 1, be water tank 10 between the wind wall of body of heater 1 and the outer wall of flue 2, the top of described flue 2 is connected with a burner 3, the head of described burner 3 and the junction of body of heater 1 have one deck insulating collar 12, the bottom of described insulating collar 12 is a horn mouth 11, the bottom of described flue 2 is connected with a base smoke box 4, described base smoke box 4 is connected with the upper smoke box 6 being located at body of heater 1 top by a two return smoke pipe 5, the flame that burner 3 sprays is in flue 2 combustion, flue gas is by flowing to upper smoke box 6 from two return smoke pipe 5 after base smoke box 4 rectification, cold water in water tank 10 by with flue 2, heat up after the outer wall of base smoke box 4 and two return smoke pipe 5 carries out heat exchange and seethe with excitement and produce steam, steam concentrates on the top of water tank 10, and carry out the heat transfer between isolated flue 2 and water tank 10 by insulating collar 12, prevent the top of water tank 10 overheated, the height of the horn mouth 11 of usual described insulating collar 12 is exactly vapor space height, the innovative point of vertical steam boiler of the present utility model is mainly that the exocoel of the upper semisection of described body of heater 1 is with a cooling jacket 7, the top of described cooling jacket 7 is equal with the bottom of insulating collar 12, the top of described cooling jacket 7 is respectively equipped with a water inlet 8 and a delivery port 9, described water inlet 8 is connected with water supply system, described delivery port 9 is connected with water tank 10.The inner surface of described cooling jacket 7 is adjacent to the outer surface of flue 2, the cooling water in cooling jacket 7 is made to absorb the heat of flue 2 and heat up, simultaneously, cooling water is by flowing into water tank 10 after heat temperature raising, make the water inlet of water tank 10 higher than the temperature of common vertical steam boiler, water can be heated to boiling with less fuel and produce steam, save fuel, the most important thing is, because cooling jacket 7 adds insulating collar 12, the heat-dissipating space at flue 2 top is improved greatly, the vapor space in water tank 10 also improves greatly, the vapor space in flue 2 is strengthened greatly, owing to solving the problem of vertical steam boiler flue 2 dry combustion method, the vapor space of boiler just can set rated capacity and the steam quality of boiler according to the height of cooling jacket 7, no longer by the puzzlement of flue 2 problems of excessive heat.In other words: vertical steam boiler of the present utility model can ensure that water tank 10 has the vapor space of enough height, thus ensures rated capacity and the steam quality of boiler.
