Title: Coal firing multi-tube boiler adapted to reduce reduction of nox and operating method thereof
Inventor: KATSUMATA MICHIO
IPC: F23B99/00
Filed: 1983-10-13
Abstract: PURPOSE:To reduce production of NOx, by a method wherein the interior of a smoke tube is divided into a primary and a secondary combustion chamber, and coal distribution density is regulated by means of a coal feeder with relation to a fluidized-bed formed in the primary combustion chamber. CONSTITUTION:In a fluidized-bed 9, coal is fed in a condition to approximately uniformly feed the air from an air feed bed 8 as dispersion density is controlled by means of a coal feeder 10. In case an amount of a nitorgen content contained in coal is very low, the coal may be dispersed so as to form uniform dispersion density, but in case coal has a high nitrogen content, the coal is controlled into dispersion density which allows provision of a combustion condition, in which production of NOx is reduced, through regulation of the number of revolutions of the swirl valve of the coal feeder 10 according to the instruction of plural thermometers previously located in the fluidized bed 9. In a fluidized-bed position in the vicinity of, for example, a flue end 11, the coal is densly supplied so that it is burnt within a range of 80-120%, based on the coal, of a theoretical air for combustion. Further, in a fluidized-bed position apart from the smoke tube end 11, the coal is coarsely supplied so that it is burnt within a range of 100- 250% based on the coal, of the theorectical air for combustion.
