摘要： PURPOSE:To make the partial repair or the construction of furnace in a short period possible by a method wherein bricks are connected with one another in pinched state by inserting bolts into the through holes formed by the notched parts of every four bricks adjacent to one another. CONSTITUTION:When the bricks 12A are disposed in crosswise arrays by abutting their notched parts against one another, the through hole 16 is formed by the notched parts 14 of the four bricks 12A adjacent to one another. In the small diametrical part 16A is inserted the shank 17A of the bolt 17, the head part of which is abutted through a washer 18 against the stepped part 19. A plurality of supporting member 20 are longitudinally fixed to an outside plate 15. After all, the outer side parts 12a to the furnace of the bricks 12A are inserted into the plurality of the spaces surrounded by every four supporting plates 21 and fastened by screwing the tips of the bolts 17 into nuts 22. In the brick aggregate 12, only the one specified brick 12A can be separated for exchange by removing four bolts 17.

摘要： PURPOSE:To prevent burning to sharply improve a durable life by providing guide plates spaced at regular intervals with surface plates over the whole width in an inner space of a fire grate block, forming cooling water passages between the surface plate and the guide plate and connecting a water feed pipe of cooling water and an drain pipe at both end parts of the cooling water flow passage. CONSTITUTION:The flow of cooling water supplied to a water feed header 25 by a pump is controlled by a flow regulating valve 27 in a water feed edge pipe 26 to feed water in each fire grate block 10 from a water feed conduit 29 of a flexible water feed pipe 28 so as to supply to the fire grate block 10. Cooling water introduced in the fire grate block 10 from the water feed pipe 21 is uniformly dispersed from a spray nozzle 20a in the width direction of a cooling water passage 18 to flow in the reverse direction to waste sent direction so as to uniformly cool the surface plate 11 of the fire grate block 10. The cooling water after cooling is drained from a water collected nozzle 22a to send water to the fire grate block 10. The cooling water by which the final fire grate 10 is cooled is supplied to a drain header 32 from a drain end pipe 31 of a flexible drain pipe 30 of a drain pipe 23.

摘要： PURPOSE:To make adjustable the difference in the height of stepped portion of furnace floor, by pivotally providing a grate stoker via a fuel discharge end portion in an incinerator having a plurality of grate stokers for forming the furnace floor. CONSTITUTION:While an usual waste 3 is being discharged out of a waste supplying hopper 1, an incinerator is operated under an usual combustion state with the stepped difference of respective grate stokers 4, 5 and 6 being maintained. As the supply of waste 3 with increased heat amount initiated, a grate stoker rotating device 8 is actuated to rock a combustion stoker 5 or a back-burning stoker 6 appropriately in the upward direction for restricting or eliminating the stepped difference of respective grate stokers 4, 5 and 6. The incinerator is thus enabled to burn the waste consistently despite the substantial variation in the quality of fuel, while accomplishing a remarkable reduction of NOX emission from an exhaust gas.

摘要： PURPOSE:To enable to stabely incinerate and operate even for the large variation of the fuel quality by a method wherein vertical walls of stepped parts are made swingable and the incineration angle is made controllable at stepped parts. CONSTITUTION:When ordinary refuse is supplied from a refuse supplying hopper 1, a step controlling flapper 8 is turned upward by a flapper turning equipment 9 as shown in the step controlling flapper 8 at the lower step, and the incineration operation is carried out with keeping the step difference. And when refuse with high calorific value is supplied, the step controlling flapper 8 is turned adequately downward, and the incineration angle is made moderate as shown in the step controlling flapper 8 at the upper step. Owing to this operation, the furnace works nearly as a single furnace, and supplied refuse with high calorific value can be stably burnt. Namely, it will be prevented that refuse with high calorific value is dropped at the stepped parts and burnt out rapidly.

摘要： PURPOSE:To prevent dust from having tackiness and remove dust efficiently by adding calcium sulphate to combustion gases and raising the melking point of dust contained in the exhaust gas. CONSTITUTION:On the combustion exhaust gas passage on the upstream side of an electrostatic precipitator appended to a refuse incinerator, calcium sulphate powder or slurry is added into combustion exhaust gases and raises the melting point of dust contained in the combustion exhaust gases. The test results of adding anhydrous calcium sulphate at 1%, 2% and 10% rates to the dust sample of Na2SO4-K2SO4- PbCl2-ZnCl2 line compounds show that the melting point of dust components rises as the added quantity of CaSO4 is increased. Therefore, even when the temperature in the electrical precipitator is above 300 deg.C, dust does not get tackiness and can be caught easily.

摘要： PURPOSE:To prevent oxidation of SiC bricks and improve the durability thereof by constituting two layers of air cooling chambers at the side wall and back surface of the incinerator, applying forced draft to the air cooling chamber on the side contiguous to the side wall of the incinerator and applying natural draft to the other cooling chamber. CONSTITUTION:The part facing the furnace combustion zone of the side walls 9 of the incinerator, is fitted with a brick assembly 11 having a configuration in which a required number of SiC bricks 11A larger than ambient bricks are disposed in parallel to each other. In this case, a shround 13 is provided around the periphery of a space between the above brick assembly 11 and an outer plate 12, and the space is partitioned into a forced air cooling chamber 15 and a natural air cooling chamber 16 by a partition plate 12A. An air blast pipe 16 branched from a combustion air feed pipe 19 led from a fan 18 to the inside of the incinerator and an exhaust pipe 19, are connected to the forced air cooling chamber 15, and the exhaust pipe 19 is directly opened from the lower part of the forced air cooling chamber 15 directly toward part of the grate.
