Abstract
Способ газификации угля, включающий загрузку и розжиг угля сверху, подачу воздушного дутья снизу и стадийное проведение процесса, отличающийся тем, что уголь 90-95%, с дополнительно введенными красной глиной в количестве 2-3% и известняком 4-5%, загружают в аппарат, верхний и нижний слои угля высотой по 200-300 мм смачивают жидким топливом и проводят розжиг верхнего слоя угля до образования слоя коксового остатка температурой 600-800°С высотой 200-300 мм путем подачи воздушного дутья с удельным расходом 75-150 м/мч, розжиг нижнего слоя угля до образования слоя коксового остатка с температурой 600-800°С высотой 200-300 мм проводят подачей дутья воздухом, содержащего 1-3% озона, с удельным расходом 100-200 м/мч,на первой стадии проводят каталитическую газификацию угля при температуре зоны газификации 600-800°С подачей дутья воздухом, содержащим 1-3% мас.% озона, с удельным расходом 700-900 м/мч и перегретого водяного пара температурой 250-450°С с удельным расходом до 150 кг/мчас, под верхний слой коксового остатка при снижении температуры слоя до 600°С подают сжатый воздух и при повышении температуры слоя свыше 800°С подачу сжатого воздуха прекращают,на второй стадии проводят каталитическую газификацию коксового остатка при температуре зоны газификации 600-800°С подачей дутья воздухом, содержащего 1-3% мас.% озона, с удельным расходом 1600-1800 м/мч и перегретого водяного пара температурой 250-450°С с удельным расходом до 450 кг/мч, при снижении температуры зоны газификации ниже 600°С подачу пара прекращают.A method of coal gasification, including loading and igniting coal from above, supplying air blast from below and stage-by-stage process, characterized in that coal is 90-95%, with additionally added red clay in an amount of 2-3% and limestone 4-5%, loaded into the apparatus, the upper and lower layers of coal 200-300 mm high are moistened with liquid fuel and the upper coal layer is fired up to form a coke residue layer with a temperature of 600-800 ° С 200-300 mm high by applying air blast with a specific flow rate of 75-150 m / mch, ignition of the lower layer of coal until I coke residue with a temperature of 600-800 ° C, a height of 200-300 mm is carried out by supplying air blast containing 1-3% ozone, with a specific flow rate of 100-200 m / mh, at the first stage, catalytic coal gasification at a gasification zone temperature of 600- 800 ° C by blowing with air containing 1-3% wt.% Ozone, with a specific flow rate of 700-900 m / mh and superheated water vapor at a temperature of 250-450 ° C with a specific flow rate of up to 150 kg / mh, under the upper layer of coke residue with a decrease in the temperature of the layer to 600 ° C serves compressed air and with an increase in the temperature of the layer over 800 ° C stop compressed air, in the second stage, coke oven gasification is carried out at a gasification zone temperature of 600-800 ° C by blowing air containing 1-3% wt. ozone with a specific flow rate of 1600-1800 m / mh and superheated water temperature 250-450 ° C with a specific flow rate of up to 450 kg / mh, when the temperature of the gasification zone is lower than 600 ° C, the steam supply is stopped.
