摘要： PURPOSE:To further lower the NOx content of combusted exhaust gas without considerably altering a construction, by asymmetrically arranging a nozzle forming an air excess pre-mixing flame around a nozzle forming an air lean diffusing flame. CONSTITUTION:In a burner comprising a nozzle 12 forming an air lean diffusing frame and a nozzle 11 forming an air excess pre-mixing flame provided close to the nozzle 12, an arrangement is altered such that the nozzle 11 forming the air excess pre-mixing flame is asymmetrically provided around the the nozzle 12 forming the air leans diffusing flame so as to halve the emission of NOx which would otherwise be produced due to a diffusing mixing between the air excess pre-mixing flame and the air lean diffusing flame.

摘要： PURPOSE:To enable an untrained person to collect spray particles easily without a difference by spraying compressed air from one side of a spray-particle induction chamber, by taking particles in from an upper collection intake by an air flow, and by dropping particles from lower supply intake on a receptacle of the collection chamber by cutting off the air flow. CONSTITUTION:Over spray particle collection chamber 23, spray particle induction chamber 22 is horizontally arranged, and compressed air 30 is sprayed through straightening vane 23 from one terminal and discharged from the other terminal. Spray particles sprayed from various atomizers are sucked from collection intake 25 provided to induction chamber 22 into induction chamber 22 by air flow and discharge from the open terminal side together with compressed air 30. When solenoid valve 27 is momentarily closed by timer 28 to stop the flow of compressed air, spray particles flowing from collection intake 25 drops from supply intake 32 provided to induction chamber 22 on spray particle receptacle 26 in collection chamber 23, where they are collected. The compressed air flow is cut off by solenoid valve 27 and timer 28, so that conventional training will not be unneeded without a difference in collection result.

摘要： PURPOSE: To improve a coefficient of desulfurization and to reduce production of NOX, by a method wherein secondary air, charged in a combustion chamber at the rear part of a combustion range, is mixed with a desulfurizing agent carried by a part of a primary air to charge the mixture.
CONSTITUTION: Coal 1 is pulverized into fine particle by a coal crusher 7, and the pulverized coal, carried by a primary air fed in the coal crusher 7 through primary air passage 11 and 11a, passes through a pulverized coal feed pipe 8 and is blown in a furnace 13 through a burner 9 to ignite it for burning. Limestone 4, serving as a desulfurizing agent, is crushed into fine particle by a limestone crusher 7b and passes through primary air passages 11 and 11b to carry it by means of a primary air fed in the limestone crusher 7b. The pulverized coal, passing through a pulverized coal feed pipe 8b, is mixed with OFA passing through a combustion air OFA passage 14, and the mixture is blown in a rear part 20 in a furnace 13 through an OFA port 15. This permits improvement of a coefficient of desulfurization and enables reduction in production of SOX and NOX.
