A waste combustion system includes a porous apparatus for supplying and spraying a suitable amount of water from at least the bottom floor surface and/or a lower inner surface of the furnace. Water vapor generated from the water is dispersed, and it undergoes the water gas reactions with red-hot carbon during a combustion process. The water gas reactions serve as the endothermic reactions which control the temperature within the furnace into suitable temperatures. In addition, while secondary air from a secondary air introducing apparatus is being supplied into the combustion chamber of the furnace, the burning zone of the waste is subjected to violent agitation and stirring actions so as to limit the generation of such substances as nitrogen oxides and soot, hence, to reduce the proportion of pollutants contained in the exhaust gases.

Waste combustion system

A 2-cycle uni-flow spark-ignition engine has an annular scavenging chamber which is communicated with a crank chamber and which is connected to scavenging ports which are opened in an end period of downward stroking of a piston. A fluid introduced into the crank chamber is pre-compressed by the downward stroking of the engine and is discharged into a cylinder chamber through the annular scavenging chamber and the scavenging ports to form a uni-flow of scavenging fluid with a swirl above the piston. The engine has an exhaust valve provided on a cylinder head and normally opened by being driven with a predetermined force exerted by driving coiled spring towards the inside of the cylinder chamber. The exhaust valve is closed in the beginning period of compressing upward stroking of the piston so as to allow compression of the mixture introduced into the cylinder chamber and is automatically opened at the end period of expansion downward stroking of the piston after explosion and generation of power, so as to enable the combustion gas to be discharged as exhaust gas.

2-cycle uni-flow spark-ignition engine

A two-stroke-cycle uniflow spark-ignition engine. A fluid sucked and pressurized by a compressor driven by the engine is delivered to an annular scavenging chamber formed in a cylinder around the entire circumference thereof, so as to be accumulated therein. The fluid within the annular scavenging chamber is discharged therefrom, through a plurality of scavenging ports formed in the cylinder and capable of opening into a cylinder chamber toward the end of a descending stroke of a piston, and/or into a recess which is above the piston, the discharged fluid serving as a scavenging fluid that flows generating a swirling uniflow. A mixture compressed within the cylinder chamber during an ascending stroke of the piston is ignited by an ignition plug for combustion.

Two-stroke-cycle uniflow spark-ignition engine

A two-stroke-cycle uniflow spark-ignition engine generates power by pressurizing fluid introduced into a crank chamber within the crank chamber with a piston as it moves toward its bottom dead center, feeding the pressurized fluid to an annular scavenging chamber provided on the entire periphery of a cylinder where it accumulates, and discharging the fluid in the annular scavenging chamber into a cylinder chamber provided above the piston from a plurality of scavenging ports which are opened at the end of the descending stroke of the piston as a scavenging fluid in the form of a swirling uniflow.
