摘要： PURPOSE:To control the temp. of a gasifier oven irrespective of a wide load variation range so as to obtain a product gas of constant calorific value, by compensating for an oven temp. decreases occurring in the stage of low load in a entrained bed type coal gasifier oven by elevation of the preheating temp. of a gasifying agent. CONSTITUTION:Coal 1 is fed into a coal gasifier oven 10 through a flow rate regulator 2. A gasifying agent 41, such as air, is fed through a flow rate regulator 42, controlled with signal 57 converted from the signal 56 of the regulator 2 by the use of a control operation unit 3, into a heat exchange 36 wherein preheating is conducted. The preheated gasifying agent 44 is fed into the oven 10, wherein the coal 1 is partially oxidized. The ash is melted and discharged as slag 17, and the crude product gas 11 is cooled by a cooler 12 and fed into a purifier apparatus 14, wherein dedusting and desulfurization are conducted. Most portion of the purified gas 15 is taken out as combustion gas 16. Portion of the combustion gas is extracted as a fuel 21 for gasifying agent preheating, and fed through a flow rate regulator 22. controlled with the temp. signal 51 of the combustion waste gas 37 discharged from the heat exchanger 36, into the oven 10 and a combustor 30 to which the air 31 controlled with the temp. signals 53, 54, 55 of the gasifying agent44 and high temp. combustion gas 35 is introduced. In the combustor, combustion is conducted. The high temp. combustion gas thus formed is fed to the heat exchange 36, wherein the gas is used to preheat the gasifying agent 43.

摘要： PURPOSE:To execute an exact measurement which is excellent in its responsiveness, by calculating a powder flow rate from the product of a powder concentration calculated by measuring an attenuation of a sound wave by powder, and a powder speed calculated by measuring a delay time between measuring points. CONSTITUTION:Powder 70 is carried by passing through the inside of a carrying pipe 80. A sound wave generator 11 generates a sound wave between 1kHz and 1kHz, and this sound wave is emitted to the inside of the carrying pipe 80 by a sound wave element 12. The emitted sound wave is attenuated due to existence of the powder 70 and reaches a sound wave element 22. The sound wave transmitted to the element 22 is detected by a sound wave detector 21, and converted to a powder concentration by a concentration detector 31. The same measurement is executed between the elements 11, 12 and sound wave elements 14, 24 separated in the flow direction of the powder 70, as well. Results of detection of detectors 31, 32 are sent to a powder average flow rate calculator 60 through an average concentration calculator 40 and a speed computing element 50. In such a way, the measurement of a powder flow rate, which is excellent in its responsiveness can be executed.

CONSTITUTION: Pulverized coal 21 and oxygen or an oxygen-contg. gas 21 are fed through a nozzle 11 to a gasifying chamber 1 and partially burnt to thereby convert it into a combustible gas which is then recovered as the produced gas from the upper part. Ash contained in coal is molten by heat generated by partial combustion, allowed to drop through a slag tap 2 into a cooler 12 to cool and solidity it with a cooling water 25 and withdrawn from a valve 14. Oxygen or an oxygen-contg. gas 24 from the upper part of the cooler 12 is fed to a space between the slag tap 2 and the cooling water 25 to burn combustible gas in the neighborhood of the slag tap 2, whereby the slag tap 2 is kept at a high temp. by generated heat to prevent clogging caused by the solidification of slag.
