摘要： PURPOSE: To reduce NO
x , by a method wherein a combustion assist air supply port and a heating burner are provided in an inlet side exhaust gas dust and controlled by the oxygen concn. in a post-stream gas and the temp. in the duct.
CONSTITUTION: Fuel and air are thrown into a fire furnace 3 to be burnt. The combustion gas is subjected to endothermic cooling in the fire furnace and passed through a rear part flue 9 to be sent to a denitration apparatus 25. A bypass gas and combustion assist air are mixed in a mixer 16 and the mixed gas is burnt and heated by a heating burner 24 provided to the downstream side. The amount of combustion assist air is controlled by a control damper 32 so as to adjust the oxygen concn. in a coal economizer outlet flue 14 to a predetermined amount. The fuel of the heating burner 24 is controlled so as to hold the inlet gas temp. of the denitration apparatus 25 to a predetermined temp. NH
3 is injected form a nozzle 20 in such a manner that the injection amount thereof is controlled so as to adjust NO
x , NH
3 at the outlet of the denitration apparatus to a predetermined amount.

摘要： PURPOSE:To obtain a roller mill capable of high classification efficiency and minimum possible cost reduction and pressure loss reduction by providing a auxiliary classification reversed cone around a rotary classifier, with a rotating blade of the classifier inclined downward, and changing an air current wgich ascends along the outer side of the auxiliary classification cone to a turning lateral air current using a deflector. CONSTITUTION:Material coal 1 is allowed to drop to a table 3 from a coal feed pipe 2 and is crushed using a roller. next, finely crushed coal 5 and roughly crushed coal 6 are caused to ascend between an auxiliary classification cone 7 and a mill casing 19 using a hot blast 4 from below the mill casing 189. Further, the coal are allowed to flow into the lifting open part 8 of a deflector 9, passing through a space with a triangular cross section between the reversed cone top of the auxiliary classification cone 7 and the upper end part of the mill casing 19. Next, the flow of the coals changes to a turning lateral current toward a rotary classifier 11, then this turning lateral current hits a downward- inclined rotating blade 10, and the roughly crushed coal 6 is sent to the bottom of the auxiliary classification cone 7, while the finely crushed coal 6 is discharged to an area outside the roller mill together with an ascending current.

摘要： PURPOSE:To evaluate the friction characteristic at the crushing time of a particulate material such as coal, by measuring the lift quantity of a tumbling body at the time of a crushing test and tumbling said tumbling body until said drift quantity becomes almost constant. CONSTITUTION:A specimen S is put in a crushing chamber 1 and the drive apparatus connected to a gear 1 is driven while the wt. of a wt. 9, that is, constant downward load is applied to balls 2 and a press plate 3 is rotated around a rotary shaft 5 to tumble the balls 2 and the specimen S is meshed with the balls 2 to be crushed. The gap with the under surface of the gear 6 is measured by a gap sensor 10 to measure the lift quantity due to the meshing with the specimen by the balls 2 being a tumbling bodies. At this time, the lift quantity of the tumbling bodies changes timewise and reaches an almost constant value with the elapse of time and, therefore, the steady value of said quantity is used in the evaluation of a friction characteristic.

摘要： PURPOSE:To decrease an amount of air for combustion leaking in exhaust gas, by providing a casing the interior of which is partitioned into four vent passages of a pass region on the high temperature gas side, an intermediate region on the gas side, a pass region on the low temperature air side, and an intermediate region on the air side, and a rotor which is rotated in the order of the four vent passages. CONSTITUTION:A casing 1 is provided with two intermediate regions between a pass region (a) on the gas side and a pass region (b) on the air side, and is connected to low pressure air through a duct by means of an intermediate region (c) on the gas side and an intermediate region (d) on the air side of the outlet of a ventilator. With a rotor 2 rotated, gas conveyed from the pass region (a) on the gas side to the region (c) on the gas side is pushed out by means of high pressure air, and the rotor is rotated to the pass region (b) on the air side in a state to fill the element of the rotor 2 with air. Meanwhile, air conveyed from the pass region (b) on the air side to the intermediate region (d) on the air side along with rotation of the rotor 2 is pushed out to the outlet side of an air preheater, and instead the element of the rotor 2 is filled with gas, and the rotor is rotated to the outlet side of the pass region (a) on the gas side. Along with rotation of the rotor 2, the above process is continued in succession, and an amount of input conveyance leak can be decreased.

摘要： PURPOSE:To detect a position of a sensor accurately with a secured movement thereof even at a high temperature by supporting an infrared sensor on a sensor mounting base through a non-lubrication metal and mounting a plurality of rings at equal intervals on a wire for moving the sensor mounting base. CONSTITUTION:A sensor mounting base 2 is supported by a main support non- lubrication metal 8 and a side support lubrication metal 9 in such a manner as to slide freely and protected with an anti-swing non-lubrication metal 10 from getting off a rail 7. With a normal or reverse rotation of a driving roller 12, a wire 11 moves slowly to reciprocate the sensor 1 over the entire range of a high temperature atmosphere 5 together with the sensor mounting base 2. A plurality of iron rings 16 mounted on the wire 11 at equal intervals are detected by a magnetic sensor 17 provided on the low temperature section 3 side, thereby enabling measurement of a correct moving position of the sensor 1.
