Description

Be used for preventing waste incinerator grate coking structure

Technical Field

The utility model relates to an energy field specifically indicates a be used for preventing waste incinerator grate coking structure.

Background

The operating period is prolonged by attempting to slow down the coking of the boiler by methods of controlling the temperature and the oxygen of the boiler, adjusting secondary air, controlling a material layer and the like, but the effect is not obvious, and the coking phenomenon of the boiler is more and more serious. After the boiler is seriously coked, the smoke gas flow area can be reduced, the garbage movement is influenced, the boiler is forced to be shut down, the coking condition of the boiler is checked, generally, the two side walls with the same elevation above a rear arch is formed, the included angle between the rear arch and the side walls is particularly serious, the rear arch and a large amount of coking of the two side walls are gradually connected into a whole, the danger of coke cleaning during the shutdown is large, the cleaning difficulty is large, the maintenance time of the boiler is influenced, large coke blocks are easy to damage a fire grate in the cleaning and dropping process, the boiler is forced to be shut down due to coking, the annual operation hours of the boiler are reduced, the shutdown times are increased, the maintenance workload is increased, the garbage incineration amount is reduced, the garbage can be blown out when the garbage amount is large, the environment is seriously polluted, and the inestimable result is brought.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome the defect of above-mentioned technique, provide a be used for preventing waste incinerator grate coking structure.

For solving the technical problem, the utility model provides a technical scheme is a be used for preventing waste incinerator grate coking structure, including the grate furnace body, the grate furnace body includes back wall, left side wall and right side wall are equipped with supplementary combustion-supporting respectively, the back wall is located to encircle the department behind the wall and has laid first burnt hole and broken the arch and help the flow ware along the horizontal direction, it is located to encircle behind the back wall first burnt hole top correspondence is equipped with first adherence tuber pipe, the left side wall is located supplementary combustion-supporting upper left side and is equipped with the second and beat the burnt hole, the second is beaten burnt hole top and is equipped with the second and adheres to the wall tuber pipe.

As an improvement, the aperture of the first coking hole adopts a gradually expanding structure from the outside of the furnace body to the inside of the furnace body.

As an improvement, the first wall-attached air pipe is connected with the secondary air pipe.

As an improvement, the second wall-attached air pipe is connected with a secondary air pipe.

Compared with the prior art, the utility model the advantage lie in: before the boiler is technically improved by a coke cleaning hole, the boiler generally runs for about 3 months, the boiler is forced to be shut down for maintenance due to serious coking, 1 boiler needs to be started and stopped 4 times per year, the diesel oil consumption amount of each start-up is about 13 tons, each ton of diesel oil is about 6000.00 yuan according to the market price, about 52 tons of diesel oil are needed for 1 boiler to start up 4 times in 1 year, the fuel oil cost is about 31.2 ten thousand, and 62.4 ten thousand yuan is needed for 2 boilers to start up in one year; after the technical improvement of the coke cleaning hole of the boiler, the coke cleaning work is carried out on the boiler for 1 to 2 times every week, the operation time of the boiler is prolonged from about 3 months to about 6 months, the number of times of starting and stopping the boiler in one year is reduced from 4 times to 2 times, the oil consumption of starting the 2 furnaces is reduced from about 52 tons to about 26 tons, the oil consumption of fuel oil is reduced from about 62.4 ten thousand yuan to about 31.2 ten thousand yuan, and after the technical improvement of the coke cleaning hole, the oil consumption and the cost of starting the 2 furnaces in one year are equivalent to the oil consumption and the cost of 1 furnace before the technical improvement of the coke cleaning hole. Greatly reduces the furnace starting cost, ensures the timely treatment of the garbage, and has considerable economic and social benefits.
