Abstract
The utility model discloses a pulverized coal industrial boiler ignition device which comprises a fire grate. A coal hopper is arranged on the top of one end of the fire grate. The other end of the fire grate is located below a combustion chamber. The width of the fire grate is 1m-1.5m, and the length of the fire grate is 4m-4.5m. The length of the part, below the combustion chamber, of the fire grate is two thirds of the total length of the fire grate. A slag discharge port is arranged below the end portion, located on one side of the combustion chamber, of the fire grate. The pulverized coal industrial boiler ignition device has the advantages of being simple in structure, low in use cost and reliable in operation.
Description
Technical field
The utility model relates to a kind of industrial coal powder boiler igniter.
Background technology
Industrial coal powder boiler has three large outstanding features: the one, and efficient energy-saving.The type boiler is take coal dust firing as core technology, and the coal dust burn-off rate can reach more than 98%, and the boiler operatiopn thermal efficiency can reach more than 88%, and this all is the target that is unable to reach for conventional boiler.And industrial coal powder boiler is compared conventional boiler up to reach the especially strong assurance of the energy-saving effect more than 35% for " 12 " object of planning.The 2nd, environment-protecting clean.By multistage pollutant removing means, can make pollutant emission standard far below existing national discharged from coal-fired boiler standard, even approach or reach the pollutant emission requirement of fuel-oil or fuel-gas boiler, also good clean-up effect can be reached to PM2.5 fine grained pollutant, strict even harsh environmental protection standard requirement can be satisfied." the 3rd, automatization level improves.Be equipped with modern automatic control technology, boiler operatiopn, defeated coal, burning, desulfurization and dedusting, slag tap etc. realized automation control, and operating personnel are few, good work environment.
At present China's industrial coal powder boiler igniting adopts fuel oil, combustion gas, plasma igniter etc. combustion-supporting; it is high that it has automaticity; the advantages such as defencive function is perfect; but all need configure special oil, source of the gas facility and plasma generator high energy facility; invest larger; consume energy higher, and have certain potential safety hazard.
The utility model content
The technical problems to be solved in the utility model provides a kind of industrial coal powder boiler igniter, and it has simple in structure, the characteristics such as use cost is low, reliable operation.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
Comprise fire grate, the top of fire grate one end is provided with leakage coal bunker, and its other end is positioned at the below, combustion chamber.
The utility model further improves and is:
The width of fire grate is 1m-1.5m, and its length is 4m-4.5m.
The fire grate length that is positioned at the below, combustion chamber is 2/3 of fire grate total length.
The below, end of grate furnace ranking one side in the combustion chamber is provided with slag-drip opening.
The beneficial effect that adopts technique scheme to produce is:
The utility model is the small-sized fire grate that is arranged in the below, combustion chamber, use common fire coal, one coal bunker coal storage is set, by the inside transporting buring coal of fire grate, the coal-fired condition of igniting is lower than the Coal powder spray condition of igniting, can ignite with firewood, after fire coal ignites, whole grate can violently burn, improve rapidly chamber temperature, reach the coal powder ignition point, close fire grate after the coal dust normal combustion and get final product, the cinder of after-flame can be protected fire grate on the grate, and cheap, the easy to operate burning raw coal of the utility model expends extremely low; The width of fire grate is 1m-1.5m, and its length is 4m-4.5m.Through experiment showed, this small-sized fire grate coal dust that can ignite, reduce its cost of manufacture, the fire grate length that is positioned at the below, combustion chamber is 2/3 of fire grate total length.Make the utilization rate of fire grate higher.The below, end that fire grate fire grate 1 is positioned at combustion chamber 3 one sides is provided with slag-drip opening 4.The coal dust of after-flame is convenient to cleaning slags tap.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In the accompanying drawings: 1, fire grate; 2, leak coal bunker; 3, combustion chamber; 4, slag-drip opening.
The specific embodiment
By embodiment shown in Figure 1 as can be known:
Comprise fire grate 1, the top of fire grate 1 one ends is provided with Lou coal bunker 2, and its other end is positioned at 3 belows, combustion chamber.
The width of fire grate 1 is 1m-1.5m, and its length is 4m-4.5m.Through experiment showed, this small-sized fire grate coal dust that can ignite, reduce its cost of manufacture.
Fire grate 1 length that is positioned at 3 belows, combustion chamber is 2/3 of fire grate 1 total length.This kind structure makes the utilization rate of fire grate higher.
The below, end that fire grate fire grate 1 is positioned at combustion chamber 3 one sides is provided with slag-drip opening 4.The coal dust of after-flame is convenient to cleaning slags tap.
Operation principle:
The utility model is the small-sized fire grate that is arranged in the below, combustion chamber; use common fire coal; one coal bunker coal storage is set; by the inside transporting buring coal of fire grate; the coal-fired condition of igniting is lower than the Coal powder spray condition of igniting; can ignite with firewood; after fire coal ignites; whole grate can violently burn; improve rapidly chamber temperature, reach the coal powder ignition point, close fire grate after the coal dust normal combustion and get final product; the cinder of after-flame can be protected fire grate on the grate, and cheap, the easy to operate burning raw coal of the utility model expends extremely low.
