摘要： PURPOSE: To provide a continuous gas sapling device, choking caused by a deposit such as ammonium hydrogencarbonate or the like generated in gathered gas can be prevented, and the gas can be introduced into an analyzer continuously and quickly. CONSTITUTION: Coal gasfication gas is gathered by a gas gathering probe 1, and introduced through a connecting pipe 15 into a ball filling filter 4 to remove dust. The gathered gas is guided from the all filling filter 4 to a scrubber 10, and ammonium hydrogencarbonate contained in the gathered gas is diluted and removed by steam jetted from an injection nozzle 18. Thus, the gathered gas from which components for choking an apparatus by deposition are removed is sent through a water dehumidifier 11 and a precision filter 12 to an analyzer.

摘要： PURPOSE:To prevent an increase in treated water and larger size of an activated sludge vessel by providing a rectifying column and absorption column, separating and absorbing low-boiling components in a stock solution using exhaust gas and cooling water from an engine as heat sources. CONSTITUTION:A stock solution 101 is preheated with exhaust cooling water 111 from an engine 2 in a heat exchanger 7, heated with heated steam 104 through a heat exchanger 5 in a concentrating vessel 1 and concentrated. A drain 105 subjected to heat exchange in the heat exchanger 5 is led to a rectifying column 11 and distilling operation is repeated with a heat exchanger 10 using exhaust cooling water 110 from the engine 2 as a heat source to separate steam 113 and treated water 112, which is then passed through an absorption column 117 to adsorb low-boiling components therein. The steam 113 is subsequently cooled in a heat exchanger 9 to store distilled water 114 in a reflux vessel 12.

摘要： PURPOSE:To determine the temp. of a 1st thermocouple when respective thermocouples make a prescribed temp. change as a clinker formation temp. and to enhance accuracy by providing the 1st, 2nd and 3rd thermocouples to the part right above a dispersion plate, nozzle part and the inside of a wind box. CONSTITUTION:The cylindrical dispersion plate 3 provided with a wind box 3a and a nozzle 3b and coal supplying nozzle 3c atop said box is disposed to the bottom of a coal gasification furnace A. The furnace A is lined with refactory casters on the inside of a stainless steel pipe 1 so that pressure and temp. can be maintained. The 1st thermocouple 6 is disposed right above the plate 3 indicating the max. temp. in the furnace 4 and the 2nd thermocouple 3 is inserted and disposed in the nozzle 3b of the plate 3 and the 3rd thermocouple in the wind box 3a. The temp. of the 1st thermocouple 6 just before the temp. change of the 2nd thermocouple 7 is determined as the clinker formation temp. when the temp. of the 2nd thermocouple 7 falls or quickly falls after a quick rise and when the temp. of the 3rd thermocouple falls quickly thereafter.

摘要： PURPOSE:To analyze the total quantity of tar having 150-600 deg.C b.p. with good accuracy from (A-C)+B by measuring the quantity A of the concentrated tar (150-500 deg.C b.p.), the quantity B of the dry solid tar (300-600 deg.C b.p.) and the quantity of the concentrated tar (300-500 deg.C b.p.) yielded by remelting of the dry solid tar after the weight measurement by gas chromatography. CONSTITUTION:The tar in the gas formed by the gasification of coal is adsorbed to an adsorbent and is dissolved in a toluene, etc., by which the tar is recovered. The tar soln. is concentrated and about 2mul the concentrated soln. of the tar is conducted to a gas chromatographic instrument, by which the tar-component is quantitatively determined. As a result, the quantity A of the tar having 150- 500 deg.C b.p. is obtd. The remaining concentrated soln. of the tar is dried and is weighed by a chemical balance, etc., by which the quantity B of the tar having 300-600 deg.C b.p. is obtd. The dry solid tar after the weight measurement is dissolved again by toluene, etc. and the tar-component is quantitatively determined by the gas chromatographic instrument. The quantity C of the tar having 300- 500 deg.C b.p. is thus obtd. The total weight of the tar having 150-600 deg.C b.p. is calculated from (A-C)+B.

摘要： PURPOSE:To collect tar under high temperature and high pressure without any closing trouble of a sampling system by cooling the tar in coal gas with steps to form tar mist. CONSTITUTION:Nitrogen gas is admitted from a guide tube 22 and is made the same pressure as that of a gasification furnace 8. Dust in the gas is collected on a filter by a holder 1 heated at 500-600 deg.C by a heater 9, the gas is guided into a holder 2 and adjusted to 150-500 deg.C by a heater 10 and then tar having a comparatively high boiling point is extracted as tar mist and collected by a filter. The gas is cooled down to a temperature close to 0 deg.C in a cooler and tar mist collected in accordance with the boiling point and density is adhered to the inwall of the cooler and collected by a filter of a holder 4. Moisture is condensed and stocked in a water tank. The tar is made tar mist in the cooler 12 in accordance with the boiling point, adhered to the inwall of the cooler 12 and collected on a filter of a holder 5. Thus, the tar more than the 80 deg.C boiling point is collected in a tar sampler.
