摘要： PROBLEM TO BE SOLVED: To provide a plasma arc type melting furnace capable of melting efficiently and reducing damage of a fire-resisting wall due to melting. SOLUTION: Three main electrodes 3 for plasma electrodes and one furnace bottom electrode 4 are arranged inside the furnace main body 2 of a melting furnace 1. The main electrodes 3 are arranged apart from one another and hung from the upper part. A furnace bottom electric current 4 is arranged roughly at the center of a triangle with the main electrodes 3 as apexes. The main electrodes 3 and the furnace bottom electrode 4 are connected with direct- current power supply equipment (not shown in Fig.) respectively. When the electric current is passed between the electrodes, the burned ash inside the furnace main body 2 is melted by plasma heat generation and the Joule heat generation in slag. Upflow is caused by a plasma jet and the blown slag flow. Since the burned ash is thrown in the intermediate part of the main electrodes 3 having a high temperature, downflow is caused to perform melting inside a liquid.

摘要： PROBLEM TO BE SOLVED: To suppress regeneration of dioxins by recombusting exhaust gas or fly ash at a specified recombustion temperature for a specified recombustion storing time and specifying air supply during recombustion thereby reducing adhesion of molten fly ash to apparatus. SOLUTION: A recombustion chamber 22 is disposed on the downstream side of a discharging opening of exhaust gas from a fluidized bed furnace 21 and on the upstream side of an exhaust gas cooling facility, e.g. a boiler. A plurality of combustion burners 28 are mounted on the furnace wall face of the recombustion chamber 22 and fly ash in exhaust gas is melted by a flame 14 from the combustion burner 28 before being exhausted from an exhaust duct 27. The recombustion chamber 22 is constructed such that the inner temperature can be st at 850 deg.C or above and at least 2 sec of fly ash storing time can be ensured. Furthermore, a free port section 23 is provided with a throat section 24 in order to set the secondary air supply rate at 50-70%, to limit the air volume to 1.5 times of theoretical air volume or less, and to limit the current velocity of primary air 4 at 1 m/sec or below thus ensuring oxygen concentration of 8% or less at the furnace outlet.

摘要： PROBLEM TO BE SOLVED: To provide an air preheater for preventing a low temperature corrosion of a heat transfer tube. SOLUTION: The air preheater for heat exchanging a combustion exhaust gas 1 with a combustion air 2 comprises a plurality of heat transfer tubes. The each tube has a tube metal part 3A covered on its outer surface with a fluororesin 4. The fluororesin 4 has a low thermal conductivity, and a heat insulation. Heretofore, a combustion exhaust gas 1 side is at a temperature bT1, while in this embodiment, the gas 1 side is at a temperature T2. At the gas 1 side of the metal part 3A, its temperature is raised by a temperature difference ΔT=T2-T1 ( deg.C) as compared with the case of a prior art, thereby becoming a dew point T0 or higher. Thus, a dew formation of the tube can be avoided, thereby preventing a low temperature corrosion.

摘要： PURPOSE:To take out molten metal to the outside of a furnace without employing a rock drill or the like. CONSTITUTION:A high-frequency coil is arranged around a nozzle tube 5 for taking out molten metal in a furnace while the high-frequency coil 2 can be heated by induction by impressing high-frequency through an inverter 3 and cooling water 4 is guided to the inside of the coil 2. The high-frequency coil 2 is heated by induction by impressing high-frequency from the inverter 3 whereby metal 1' in the nozzle tube 5 is molten and the molten metal 1 in the furnace is taken out of the furnace by a pressure due to the head of the molten metal 1 in the furnace. When the impression of the high-frequency is stopped, the metal 1' in the nozzle tube 5 is cooled and solidified by cooling water 4 whereby the flow-out of the molten metal 1 in the furnace can be stopped.

CONSTITUTION:A denitration bag filter whose denitration capacity is deteriorated is detached from a denitration apparatus. Both ends of the detached bag filter 1 are attached to an attaching stand 2 to be arranged in a flush toilet 3. Water is sent into the flush toilet 3 from a fresh water tank 4 until the bag filter 1 is perfectly immersed in water and a water stream pump 5 is operated to wash the interior of the bag filter 1 by the water streams from the emitting nozzle 6 to wash off the reactional product and catalyst bonded to the bag filter 1. The bag filter 1 after washing is immersed in a catalyst soln. to support a catalyst on the bag filter 1. Thereafter, the bag filter 1 is dried in a dryer to be regenerated as the denitration bag filter. A method performing regeneration in the denitration apparatus is also provided.
