摘要： A first-stage furnace (10) for partial combustion of solid fuel and oxidizer gas to generate inflammable exhaust gases which are passed to a secondary-stage furnace (17) is shown. The first-stage furnace (10) comprises a vertical cylindrical pre-combustion chamber (1) and a cylindrical main combustion chamber (2) mounted in horizontal position. The air-fuel mixture introduced into the pre-combustion chamber (1) is given a swirling motion and burned at a temperature that converts the mixture to a mixture of incompletely burned fuel particles, exhaust gases and non-combustible products in molten state. The mixture flows through a tangential passage (2c) into the main combustion chamber (2) and develops into a high-velocity vortex, with the molten slag being centrifuged onto the inner wall (2b) of the main combustion chamber (2) to form a film which is removed through a tapping port (6). Thus, the generated inflammable gases are free from non-combustible products such as ash, and conveyed to the secondary-stage furnace (17), through a duct (12).

摘要： PROBLEM TO BE SOLVED: To improve stabilized ignition from a low load to a high load and a flame holding ability, and reduce the generation of NOx by providing a concentration adjusting means which unifies a concentration distribution of pulverized coal on the upstream side of a pulverized coal support pipe, and providing a slewing degree control means which charges pulverized coal into a combustion furnace at an optimum slewing angle on the downstream side of the pulverized supply pipe. SOLUTION: Pulverized coal crushed by a coal crusher is conveyed together with a carrier air by way of a pulverized coal supply pipe 15 and flows into a pulverized coal bend 8. The pulverized coal/carrier-air which have flowed into the bend 8 are turned substantially at right angles and flow into a pulverized coal supply pipe 3. The pulverized coal/conveying-air which have flowed in are pushed by a slewing blade 14 provided in the pulverized coal supply pipe 3 so that the pulverized coal is pushed against the inner wall surface of the supply pipe 3, thereby reducing the ratio between the air and the coal. The pulverized coal and the conveying air with a slewing component imparted flow further toward the downstream side, their degree of slewing is reduced and adjusted by a slewing degree control blade 9 near the tip of a burner, and it is charged into a combustion furnace 2.

摘要： PURPOSE:To provide a structure capable of preventing the adhesion and growth of the mist of sintered ash contained in the gas exhausted from a gasification furnace in a duct or a reactor of a coal-gasification apparatus provided with the gasification furnace and the reactor. CONSTITUTION:A gasification furnace is a pressure-type partial-combustion furnace having the inner surface of a water-cooled slug self-coating structure in the main body. A reactor is placed at the downstream side of the gasification furnace. A gas duct is placed between the outlet of the gasification furnace and the inlet of the reactor. A part or whole of the gas-contacting surface of the gas duct is constituted with an exposed cooling wall.

摘要： PURPOSE:To prevent a local overheat from occurring, by installing a finned heater of a Stirling engine in an outer circumference at a cylinder upper part, while setting up a combustion chamber as surrounding the periphery, and installing a burner in this combustion chamber in a tangential direction. CONSTITUTION:An annular passage 6 interconnecting to a regenerator 15 is interconnected to an expansion chamber 4, and each fine 9 is installed at both surfaces of a wall 5 demarcating the outside of this passage 6. A combustion chamber 11 is installed in an outer circumference of this fin 9, and four burners 8 are set up in a tangential direction ofa cylinder. Combustion gas transmits its heat to the fin 9 while being rotated in the annular combustion chamber, and it is discharged out of an exhaust port 12 at an upper part, then exhausted by way of an air preheater 14. With this constitution, such a part that is locally overheated is brought to nothing.

摘要： PURPOSE:To control effectively generation of NOx and unburnt contents in ashes by contriving combustion by a method wherein as for an upstream side (under a state of surplus oxygen), fuel is supplied by specifying only coarse particles and as for a downstream side (under a state of oxygen starvation), the fuel is supplied by specifying only fine particles. CONSTITUTION:As for pulverized coal crushed by a mill 12, only coarse and fine particles are supplied to an upstream side burner 2 and a downstream side burner 3 respectively by a classifying device 13, an air quantity making the upstream side burner 2 into a surplus state of air is supplied to the burner 2 and the air quantity is supplied to the downstream side burner 3 so that the burner 3 is made into a starvation state of the air, through which combustion is performed within a furnace body 1 while they are being mixed with each other. In consequence of the above, along with control of generation of NOx generation of unburnt contents is controlled also and even if the unburnt contents are generated, discharge quantity itself is controlled sufficiently as a generating position is on an upstream side and sufficient dwell time for burning out unburnt contents can be taken until the unburnt contents are discharged even if the unburnt contents are generated.

摘要： PURPOSE:To provide a method and an apparatus for performing a partial gasification and generating power with coal in which a high efficient system reducing a heat bypassing amount less than the prior art system under a combined cycle with coal (fine powdered coal) being applied as fuel and the gas turbine and the steam turbine being combined to each other. CONSTITUTION:A part of fed coal is changed into gas through a partial coal gasification furnace 40, and the charcoal (residual coal) not gasified is completely ignited under a condition of excessive air and no cooling state through a pressurized circulation fluidized bed type incinerator (charcoal combustion furnace) 4. After dusts are removed from gas generated at the partial gasification furnace 40, the coal is separately ignited within the charcoal combustion furnace combustion gas where gas is already removed and then the gas turbine 20 is driven with this combustion gas.
