CONSTITUTION: A gas-extracting line 14 comprises a desuperheater 15, a flow rate detector 16, flow regulating valves 17, 15, a flow rate detector 16, a flow regulating valve 17 and an induced draft fan 18, and one end of the line 14 is connected to and communicates with a space below a slag discharge hole 6 and another end of the line 14 is connected to and communicates with an auxiliary combustion chamber 5. Extraction gas extracted after passage through the slag discharge hole 6 from the auxiliary combustion chamber 5 is cooled by the desuperheater 15 and forcedly induced by the induced draft fan 18. The amount of the extracted gas is detected by the flow rate detector 16 and on the basis of the detected value a flow controller 19 operates the flow regulating valve 17 in such a manner as to keep the extraction rate of the gas constant, Thus, temperature of the slag discharge hole 6 is prevented from being lowered and molten slag can stably be discharged.

Next, the operation of such a device will be described. First, the fuel injected from the fuel injection nozzle (3) mounted on the upper part of the cylindrical and vertical main combustor (1) is the same as the air injection nozzle tangentially mounted on the upper part of the main combustor (1). Along with the air introduced from (4), it gasifies and burns at a high temperature while swirling to reach the throat (2) at the outlet. At this time, the ash contained in the fuel melts at a high temperature and reaches the wall surface of the main combustor (1) by the swirling force of the combustion gas to form a molten slag layer flowing down the wall surface. This molten slag flows into the bottom of the sub-combustor (5) via the throat (2) at the lower end of the main combustor (1). Also,
Since the combustion gas is blown out from the throat (2) at the outlet of the main combustor to the sub-combustor (5) at high speed, the fine slag contained in the combustion gas is given an inertial force and is thus added to the sub-combustor (5).
It collides with the bottom slag layer and is attached and collected. The molten slag that has collected the fine slag in this way flows down into the slag bin (7) through the slag discharge hole (6) provided at the lower end (right end in FIG. 2) of the sub-combustor (5) and is discharged.

Most of the combustion-produced gas from which the molten slag has been removed at the slag discharge hole (6) is the gas duct (8),
It goes through (9) to the secondary combustion furnace (10) and is completely combusted by the secondary air. Further, a part of the combustion product gas is introduced from the slag discharge port (6) to the secondary combustion furnace (10) through the gas vent pipe (12) opened below. As a result, the temperature drop in the vicinity of the slag discharge port (6) is prevented, and the molten slag flow-down extraction operation is maintained well.
This extraction amount is measured by the orifice (13).

The exhaust gas completely combusted in the secondary combustion furnace (10) is sent to a boiler or the like to heat and evaporate the feed water. The main combustor (1) and the sub-combustor (5) may be constituted by water cooling walls to recover heat. In conventional coal-fired boilers, a large amount of coal ash is generated as a residue, so it was difficult to dispose and manage it. It can be solidified by crushing, etc. to have a bulk of about half that of coal ash and can be used as a building material. Therefore, the ash disposal yard is extended,
The scattering of polluted ash and the elution into water are prevented. Melt combustion also suppresses deterioration of heat transfer performance due to ash adhering to the boiler heat transfer tube and ash erosion.

The purpose of extracting the combustion gas from below the slag discharge hole (6) is to pass the hot combustion gas through the slag discharge hole (6) so that the temperature of the slag discharge hole (6) is reduced. It is to suppress the decrease and maintain the fluidity and discharge of the molten slag in good condition. However, in the above conventional apparatus, the amount of extracted gas is inevitably determined by the pressure difference between the auxiliary combustor (5) and the secondary combustion furnace (10). Therefore, when the amount of combustion gas decreases due to partial load operation, low air ratio operation, etc., the above differential pressure also decreases,
The amount of drawn gas also decreases. When the amount of drawn gas decreases, the temperature of the slag discharge hole (6) decreases, and the viscosity of the molten slag in the slag discharge hole increases accordingly, and in the worst case, the slag discharge hole is closed.

It is connected to a secondary combustion furnace (10) to obtain a differential pressure, but the gas to be extracted is a combustible gas containing CO, H 2 , CH 4, etc. and contains unburned carbon. However, since this is introduced into the outside of the main combustion zone of the secondary combustion furnace (10), the diffusive mixing of air is bad, and the amount of CO and the like at the outlet of the secondary combustion furnace (10) increases.
