A New High Efficiency Smokeless Backburning Boiler

Abstract

The invention discloses a novel efficient smokeless counter-burning boiler, and relates to counter-burning hot water boilers. The novel efficient smokeless counter-burning boiler comprises a boiler body, a boiler body water bag and a water pipe counter-burning grate. A destructive distillation burning chamber is located above the water pipe counter-burning grate, a counter-burning burning chamber is located below the water pipe counter-burning grate, a steel roller grate is arranged at the bottom of the counter-burning burning chamber, the destructive distillation burning chamber is provided with an air supplement boiler door, a fire passing opening is formed in the rear side of the counter-burning burning chamber to be in joint with a smoke discharging pipe of a smoke waste heat water bag and the smoke discharging pipe is connected with an air inducting opening 21. The ratio between the height of the destructive distillation burning chamber and the height of the counter-burning burning chamber 7 is 5:3 to 5:4. The novel efficient smokeless counter-burning boiler has the advantages that due to the reasonable design of the water pipe counter-burning grate, the air supplement boiler door, the fire passing opening (the air inducting opening), grate air ventilation coal falling gaps and the inclination, the air permeability of a destructive distillation coal seam of the counter-burning grate is good, fire-returning burning is sufficient, counter burning is realized on the upper portion in the counter-burning burning chamber, positive burning is realized on the lower portion in the counter-burning burning chamber, the temperature is as high as that of a composite burning chamber, and burning is sufficient. The boiler is sufficient in heat exchanging, smoke waste heat is well utilized, energy is saved, high efficiency is realized, and the novel efficient smokeless counter-burning boiler is smokeless, dustless and environmentally friendly.

Description

Technical field: [0001] The invention relates to a hot water boiler, and mainly relates to a high-efficiency smokeless reverse-burning boiler. Background technique: [0002] Most of the existing vertical or horizontal hot water boilers are normal-fired boilers, whose structure from bottom to top is the ash chamber, the grate, the furnace combustion chamber, the upper flue, the flue water bag, and the chimney. The new coal is put into the furnace from the coal inlet, and it is on the top of the coal seam. During the combustion process, the new coal is dry-distilled first, and then the volatile matter is burned into a red carbon layer, and then further burned and burned out. The flue gas and volatile combustion flue gas flow upwards from the top of the coal seam and the inside of the coal seam. These new coals that have just entered the combustion process are precipitated and discharged prematurely as particulate smoke dust before they burn to red charcoal and burn out. Excee...

Problems solved by technology

[0004] The above is only the ideal situation of the reverse combustion boiler. However, due to the design reasons of the existing reverse combustion boilers in reality, there are many deficiencies. First, the position of the reverse combustion grate and the height in the furnace , The inclination angle of the anti-burning grate and the size of the coal leakage gap are not reasonable enough, so the anti-burning effect is poor

The second is that there are also unreasonable things about the air supply furnace door above the backfiring grate, the height of its setting, and the relationship between it and the normal height of the new coal seam to be cast, so that the air supply situation during backfiring is not related to that of the backfiring The air volume required for burning does not match. Thirdly, the position of the burner opening (introduced air outlet) on the rear side of the anti-burning chamber is set unreasonably.
