본 고안은 생활쓰레기 소각에 관한 것이다. 본 고안의 교반기소각로(A)는 가정, 공장, 병원, 학교, 공공기관, 등에서 발생하는 생활 쓰레기를 완전소각하는 교반기소각로(A)로서 생활쓰레기를 투입호퍼에 넣으면 파쇄기에 의해 파쇄되며 회전 분쇄날에 의해 잘게 절단되어 쓰레기가 교반기소각로(A) 내 1차 교반실 2차교반실올 통과 하는 동안 완전 건조된후 교반날개의 회전력에 의해 연소실로 분산 높은 열에 의해 완전 연소되며 또 교반과정에서 발생된 수증기와 가스는 송풍기에 의해 응축기를 통과 하면서 수증기는 응축기(18)내에서 응축되어 물로 배출되고 가스는 재순환 송풍기(23)에 의하여 교반기 소각로(A)연소실로 공급되어 완전연소후 집진기(13)로 배출된다. 소각 할 때 발생되는 냄새와 가스를 제거 깨끗한 환경을 지킬수 있는 열 효률이 높온 교반기 소각로이다.
Abstract:
Fuel mixed in water is combusted in a reactor having an internal operating pressure and temperature greater than 3200 psi and greater than 374° C., where the combustion of the fuel is exothermic. Air and fuel are pressurized for introduction into the reactor to a pressure greater than the internal operating pressure using energy generated from the combustion of the fuel, and the pressurized air and the pressurized fuel are injected into the reactor. Pressurized water from the reactor is injected into a drive water column that is partially filled with water to increase a pressure of the drive water column, and water at a temperature less than 100° C. is injected into the reactor to replace water from the reactor that is injected into the drive water column. Pressurized water from the drive water column is used to drive a hydroelectric drive system to produce electrical power.
Abstract:
The invention relates to a process for firing an industrial furnace, in particular for electricity generation, wherein coal or cokes together with a secondary fuel comprising cellulose and plastic, in the form of pellets of a size larger than about 3 mm thickness, and having a caloric value of about 16 GJ/ton or more is ground to a powder wherein about 95 wt % or more has a particle size smaller than 2 mm and wherein the d50 of the particle size distribution is between about 5 and about 100 μm, wherein the powder is injected in the flame of the furnace. In this process the grinding is performed in a roller mill or ball mill, and the amount of pellets used together with the coals preferably is about 3 wt % or more, relative to the coal.
Abstract:
A system includes a solid feed pump having a housing, a rotor disposed in the housing, a curved passage disposed between the rotor and the housing, a solid feed inlet coupled to the curved passage, and a solid feed outlet coupled to the curved passage. Also, a solids packing device is coupled to the solid feed inlet of the solid feed pump. The solids packing device includes a first channel configured to receive a solid feed with a first range of sizes, a second channel configured to receive transport assisting particles (TAP) with a second range of sizes. The first range is different from the second range. A third channel is configured to receive and mix the solid feed and the TAP to provide a solid feed-TAP mixture with the TAP filling interspatial spaces between the solid feed. The third channel is coupled to the solid feed inlet.
