Abstract
Belong to the boiler manufacturing and transform to solve energy-conservation source, smoke abatement and dust control, boiler the low temperature distillation chamber is set, solve over-emitting black exhaust, contaminated environment, waste energy, solve the burning low grade coal slag and fire energy savings again.
Adopt the scraper-type chain of metal and the compound manufacturing of nonmetal heatproof material, the one, design needs, and the 2nd, it is simple and easy to make maintenance and installation, and the 3rd, save steel, the 4th, the developing nonmetal heatproof material is used on boiler.
Description
The combustion system of existing boiler is based on traveling-grate stoker, reciprocating grate, and the preheating of combustion process is dried to be stayed, burning, and surplus combustion is to finish on fire grate, with mode energy-saving dedustings such as dedusters.
The objective of the invention is energy savings, solve boiler over-emitting black exhaust, contaminated environment.
Characteristics of the present invention on boiler structure preheating, driedly stay, burning, surplus combustion divide four ones.
Under metal and the compound manufacturing flight chain drive of nonmetal pressure-resistant material, once finish.Without deduster.
Body construction: be positioned at the boiler center of top by a single drum (6), every side is formed the radiation and convection heating surface by 5 row φ, 57 * 3 tube banks (10) in both sides, connects with φ 273 * 10(2) lower collecting box.Be arranged vertically in the both sides at two ends 1 of every side totally 4 φ 159 * 8(2) by drum and lower collecting box, laterally connect on the pipe, divide two-layerly up and down, totally four φ 108 * 6 pipes in two ends are vertically divided along drums and are added special-shaped heat proof material in the middle of two-layer four every layer φ 83 * 6 pipes connect with φ 108 * 6 pipes up and down and form cryogenic dry retention to do combustion chamber (8) material therefor must be boiler material.
Stove is by δ 8mm(A
3) the plate welding fabrication, base (18) is made the air compartment of interlayer, by the device of reconciling air quantity is arranged.Province's stove device (13) that φ 273 * 10 forms with the boiler tube of φ 38 * 3 is installed in the end and takes.Seat (18) economizer (13) top is the combustion chamber fire grate by the fixed grate (14) of dress.Economizer (13) bottom fixed grate is slag burner row again.
The kind of drive
By four speed reducers is that power connects driving shaft, and driving shaft drives the sprocket wheel on the driven shaft, and wheel drive flight chain (9) driving shaft drives slag simultaneously and fires chain again.Drive coal bunker coal (5) by (9) and enter cryogenic dry retention chamber (8), fall into combustion chambers burn after coal is near burning-point, volatile matter is participated in burning in first combustion chamber.Solution is in suspended state in combustion process, carbon enters the problem that over-emitting black exhaust that atmosphere causes solves burning inferior coal.
Heat content 650-700 ℃, phosphorus content 20-25% slag falls into slag and fires the chamber again and burn away and solve the saving problem.
The heat that slag fires is again absorbed by economizer (13), and steam boiler can be used to the heated feed water hot-water boiler can (the 13) Lian Jie And net heat supplies of same economizer.
Flue gas flow
(10) are arranged vertically with refractory brick and make it to become three backhauls in the tube bank of both sides.The flue gas that slag fires the chamber again passes economizer (13) and enter first combustion chamber after preheating enters the first combustion chamber cold air.First combustion chamber also is first backhaul.Second backhaul be the 1st, 2,3 combs to vertical partition wall, the 3rd backhaul 4,5 combs to.
By dress
Boiler adopts separately-loaded to build a wall around boiler combination back.
Decelerator, axle, sprocket wheel, flight chain are again by dress.
For to the chain protection, prevent to smolder, respectively build a sealing chamber (11) sealing chamber behind the stokehold and reach sealing supervision, maintenance requirement.
Description of drawings
Boiler is made up of pot and two ones in stove.
The heat energy conversion of pot is made drum (6) φ 273 * 10 pipes by φ 1024mm boiler plate and is made next part case (2) 10 row φ 57 * 3 and forms convection current radiation heating-surface (10) and form cryogenic dry retention chamber (8) by φ 159 * 6 pipe φ 108 * 6 pipe φ 83 * 4 pipes and form pot by above-mentioned three ones.
Stove δ 8mm steel plate is made base, and the effect that φ 273 * 10 pipes and φ 38 * 3 pipe composition economizer (13) fixed grate (14) fixed grate (15) slags fire chain composition stove stove again is burning.
Claims (4)
1, cryogenic dry retention, slag fires again, scraper plate driven type boiler.
The main combustion system of boiler solved energy-conservation and smoke abatement and dust control based on the traveling-grate stoker reciprocal grate with various dedusters and supplementary means in the past.
Characteristics of the present invention are provided with a cryogenic dry retention chamber (8) and are positioned in the middle of drum and the header (2) in pot, slag is set in stove fires chamber (17) flight chain (9) kind of drive again and constitute and do not need deduster.
2, boiler is characterized in that in the middle cryogenic dry retention chamber (8) of boiler according to claim 1
3, in the middle of according to claim 1 on the base of its feature boiler of boiler slag is set and fires chamber (17) again.
4, according to claim 1 boiler to it is characterized in that carrying the kind of drive be the flight chain transmission system of metal material and the compound manufacturing of nonmetal heatproof material, the first cover scraper plate (9) is positioned in the middle of the cryogenic dry retention chamber and (14) second overlaps scraper plates and be positioned at slag and fire chamber (17) again on the first combustion chamber fixed grate
