TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The gas storage tank is connected with a thermoelectric generator and a heating boiler for supplying combustible gas. The heating chamber is provided with a furnace which is set in an ignition heater. The ignition heater is connected with a first heat energy storage tank. The furnace bottom is set with a strip-shaped separating grid. The strip-shaped separating grid bottom is provided with a discharging machine which is set with a discharge port. The first heat energy storage tank is arranged with multiple heating tubes. The upper part of the heating chamber is set with a gas filter chamber. A heater is set between the gas filter chamber and the heating chamber. One side of the gas filter chamber is set with a gas outlet which is connected to the gas purification tower. The top part of the gas converter is set with a first feeding seal mechanism, used for compressing the waste to push close into the gas converter. The feed opening of the first feeding seal mechanism is set with multiple first distributor, which is used for uniform distribution of the waste. One side of the gas converter is set with a second heat energy storage tank, which is connected with a multiple heating tubes. The lower part of the gas converter is set with a mixed gas distributor. The mixed gas distributor bottom part of the gas converter is set within a mixed gas distribution chamber. The mixed gas distribution chamber is internally set with a first ash conveyor. The mixed gas distribution chamber is connected with a cracking reactor of the corresponding chamber via a first conduit. The gas filter chamber is connected with the upper part of gas converter through a mesh block material clapboard. The cracking reactor top end is set with a second feeding seal mechanism, used for compressing the waste to push close into the cracking reactor. The feed opening of the second feeding seal mechanism is set with multiple first distributor, which is used for uniform distribution of the waste. The bottom of the cracking reactor is provided with a heat distributor, which is connected with a multiple heating tubes via second heat storage tank. The lower part of heat distributor is set with a combustible gas storage chamber. A transverse horizontal hypoxia decomposition chamber is set between the combustible gas storage chamber and heat distributor. The lower part of the transverse horizontal hypoxia decomposition chamber is set with a porous separating plate and oxidation chamber, and its upper part is set with a gas loop tube. The combustible gas storage chamber is connected to gas loop tube and gas collection tube. The combustible gas storage chamber is internally set with a second ash conveyor. The first ash conveyor is connected with the second ash conveyer, used for adding ash slag into the collector produced by the gas converter and cracking reactor. The bottom of the combustible gas storage chamber is set with a water seal pressure relief tank.
