Abstract
The utility model relates to a heating equipment, particularly a pressureless boiler. The utility model mainly comprises a boiler shell, a stove chamber, a stove grate, a radiating arch, a secondary wind pipe, a convection pipe and an ear shape plate. The boiler is provided with a semicircle shape radiating arch with an interlayer water jacket above the stove grate, two groups of secondary wind pipes between the two sides of the radiating arch and the stove grate, and an ear shape plate arranged at the two sides of the convection pipe, so the heating area of the boiler is added, the thermal efficiency of the boiler is increased, and the combustible gas can be burned completely; a gas passage at the two sides of the convection pipe is eliminated, the temperature of the exhaust gas is decreased, and the utility model has the double function of energy saving and smoke eliminating.
Description
The utility model relates to a kind of heating equipment, and particularly a kind of radiation arch formula fixedly hand is burnt pressure-less boiler.
The vertical hand of using in the city burns pressure-less boiler now, because its structure is unreasonable, to making the thermal efficiency low, has not only wasted a large amount of fuel, still causes environmental pollution.
The utility model aims to provide a kind of rational in infrastructure, thermal efficiency height, the fuel saving, not the radiation arch formula of over-emitting black exhaust fixedly hand burn pressure-less boiler.
For achieving the above object, the utility model mainly is made of shell, flue, fire grate, radiation arch, secondary air channel, convection tube and ear template etc.Furnace shell becomes sandwich with flue.Be provided with fire grate in the flue, above fire grate, establish a radiation that is semicircle shape and encircle.Radiation arch bottom is to be made of refractory concrete, and the intercalated water sleeve of a metal is arranged on it.Between the both sides of radiation arch and fire grate, are furnished with two groups of secondary air channels.Convection tube is arranged in the top of flue, is provided with the ear template in the space, both sides of convection tube.Intercalated water sleeve, convection tube on the radiation arch all communicate with the sandwich portion of ear template with the same flue of shell, shell.
Owing to take said structure, the utility model has the advantages that: one, the semicircle shape radiation arch of strap clamp layer water jacket is set above fire grate, has not only improved fire box temperature, and increased heating surface area.Under the effect of radiation arch, high-temperature flue gas can only be discharged from the both sides of arch, and the both sides of arch are nearer apart from the grate on the fire grate, and the flame export temperature is raise, and fuel gas is after-flame and eliminated black smoke as much as possible.Its two, between the both sides of radiation arch and fire grate, be equipped with two groups of airducts, secondary wind has strengthened the stirring to the burner hearth flue gas, provides the oxygen of even abundance to fuel combustion, helps fully burning and eliminates black smoke.Three, be provided with the ear template, eliminated the flue gas corridor, reduced flow area, thereby improved flue gas flow rate, reduced exhaust gas temperature, increased the thermal efficiency of boiler in space, convection tube both sides.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with accompanying drawing, further set forth specific embodiment of the utility model.
Referring to accompanying drawing as can be known, the utility model mainly is made of shell 1, flue 2, fire grate 3, radiation arch 4, convection tube 5, ear template 6 and secondary air channel 7 etc.Be provided with flat head 11 on the top of furnace shell 1, on flat head 11, be provided with pressure gauge stand 12, water outlet base 14.Be provided with backwater base 8, blowdown base 17 and ash door 18 in the bottom of shell 1.Also be provided with fire door 15, hand hole 16 in the body of heater bottom.2 one-tenth sandwiches of shell and flue, the bottom of flue 2 is provided with fire grate 3, establishes a radiation that is semicircle shape and encircle 4 above fire grate 3.The bottom of radiation arch 4 is to be made of refractory concrete, the intercalated water sleeve that has a steel plate to make on it.Between radiation arch 4 and fire grate 3, are furnished with two groups of secondary air channels 7.Convection tube 5 is arranged in the top of flue 2, is provided with ear template 6 in the space, both sides of convection tube 5.Joining with flue top 10 and flue 2 respectively up and down of ear template 6, be provided with impact tube 13 in the centre of flue top 10 and flat head 11.Intercalated water sleeve on the radiation arch 4, convection tube 5 all communicates with the sandwich portion of ear template 6 with flue 2, shell 1 with shell 1.
