摘要： PROBLEM TO BE SOLVED: To operate a melting furnace by reducing auxiliary combustion rate while keeping intended temperature. SOLUTION: Control structure of a refuse gasification melting furnace of char separation type is provided. In the structure, stable supply of char, which is an advantage of the furnace, is sufficiently utilized, and even if there is a disturbance, such as calorific value variation of refuse, manipulated variable of char supply rate, auxiliary combustion rate, air supply rate or the like can be calculated so that controlled variable such as of gas temperature in the furnace satisfies operation requirements, by using a map control technique. Thus operation with combustion air rate of around 1 is rendered possible.

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.

摘要： PURPOSE:To reduce the power cost for fluidization and suppress the generation of NOx by utilizing as the fluidized medium in a fluidized bed post-incinerator the ashes from the incineration themselves, using for the fluidization the exhaust combustion gas obtainable after heat recovery, and supplying the objects of incineration through a cyclonic incinerator attached to the fluidized bed section. CONSTITUTION:A dehydrated cake is separated into dry sludge and exhaust gas by means of a cyclone 3, which are fed together with high temperature-incinerating air into a cyclonic pre-incinerator 4 for partial combustion; the unburned gas and ashes produced therefrom are led into the fluidized bed 6 in a fluidized bed post-incinerator 5. Then, an excess of air is drawn into the freeboard section by an air feed inlet 8 so as to burn the unburned gas completely. The exhaust gas containing residual oxygen is passed through heat exchangers 10, 11 to a cyclone 12, where it is separated into incineration ashes and exhaust gas; the last-mentioned exhaust gas is drawn into a dry type electrostatic precipitator 13 and released through a chimney 14. Part of the exhaust gas discharged from the electrostatic precipitator 13 is returned to the fluidizing gas inlet 15 at the bottom of the post-incinerator 5 so that it is used to fluidize the incineration ashes and also for secondary combustion of the unburned gas wherein the residual oxygen in the exhaust gas is put to use.

摘要： PURPOSE:To prevent burnt ashes from scattering in the air and to prevent harmful substances from dissolving into underground water during the treatment of the burnt ashes by providing a burnt ash recovering means respectively at the lower part of a boiler proper and at an exhaust gas flue duct part to recover the burnt ashes containing char therein for the recombustion of the same. CONSTITUTION:An ash recycling fan 4 is opened to the air on its inlet side and is provided with a burnt ash recycle duct 5 on its outlet side. To the duct 5 are connected the ash discharge duct of a flue gas dust collector 3, the lower ash discharge duct 6 of the contact unit of a boiler proper 2 and the lower ash discharge duct 7 of the combustion chamber of the boiler proper 2. Burnt ashes discharged out of respective parts are directed into a separator 8 for recycle ashes, and the burnt ashes and air are separated from each other. The separated burnt ashes are stored in a recycle ash bottle 9. The lower part of the recycle ash bottle 9 is connected to a pulverized coal duct 13, and the burnt ashes are continuously directed into the pulverized coal duct 13. The burnt ashes are fed into a cyclone coal combustion furnace 1 together with the pulverized coal transferred by air blown out of a primary blower 12, and unburnt char contained in the burnt ashes is thereby burnt. Thus, the burnt ashes are reduced to a molten state to be discharged to the external side through a discharge port.
