Operation principle of the present utility model is:
At first, bole is put into upper strata cold water fire grate 16, and light.Put into a certain amount of coal from upper furnace door 7 to throwing coal chamber 26 then and ignite, continue stoking 17 afterwards again.Air enters burner hearth 18 from the top in upper strata water-cooled grate 16 coal seams under the effect of air-introduced machine.New coal seam on the upper strata water-cooled grate 16 is subjected to heating from the high temperature heat radiation in following red-hot coal seam, discharges a large amount of volatile matters through super-dry.After this volatile matter and air mix, fully burn through red-hot coal seam and ash bed.Coal becomes coke button after removing volatile matter.Wherein most of coke button burns on upper strata water-cooled grate 16, and volatilizes a large amount of heats, and the little coke button 23 of sub-fraction is fallen lower floor's fire grate 8 from 16 groups of upper strata water-cooled grates and burnt.A large amount of high-temperature flue gas that burning is produced, part heat is absorbed by upper strata water-cooled grate 16, and most of flue gas enters the heat convection section that is made of thin formula heat exchange wall by high-temperature flue gas outlet 11, promptly, flue gas by high-temperature flue gas outlet 11 at first enters secondary furnace 19, then under the stopping of following isolation water wall 31, flue gas enters front smoke chamber 20 along the space between the first thin formula heat exchange wall 3 and the second thin formula heat exchange wall 5, afterwards, again under the stopping of last isolation water wall 30, smoke-box 21 during flue gas enters by the space between the second thin formula heat exchange wall 5 and the 3rd thin formula heat exchange wall 12 enters rear smoke chamber 22, subsequently to proceed quick heat exchange.At last, after flue gas invagination smoke pipe 13 carries out heat exchange once more, enter atmosphere by smoking box 6.Like this, make the flue gas route that rises from burner hearth 18 S-shaped, not only increased the formation and the resistance of flue gas, and increased heating surface area greatly.Simultaneously, when flue gas circulates, because through double-layer inverse burning, its volatile matter is able to abundant burning, and when flowing into smoke-box, the dust granules multiple impact isolation water wall that is mingled with in the flue gas, and be folded to when flowing, exhaust gas dust sinks under the effect of gravity, separates with flue gas, further purify flue gas, reduced blackness of exhaustion.The dust of institute's sedimentation falls into left dust chamber 24, dust chamber 10 and the right dust chamber 9 on the base 1 respectively, and can pass through shoot door disposed thereon, dust out.
The utility model is compared with conventional hot water boiler, its Hydraulic Power System is simple in structure, connection and reasonable arrangement, after in high-temperature flue gas, adopting thin formula hot water wall heat convection, avoided single-phase medium (hot water) that vaporization or security incidents such as booster that subcooled boiling caused take place under various operating conditions, made Hydraulic Power System more safe and reliable.
