Abstract

Изобретение относитс  к сжиганию газообразного топлива во вращающейс  печи при обжиге карбонатов. Цель изобретени  - уменьшение количества образующихс  при горении топлива оксидов азота. Сущность изобретени : необходимо подавать непрерывно в факел пар с расходом 0,03 - 0,08 кг/м газообразного топлива. Характеристика: количество NOX (мг/л) - 130 - 290. 1 табл.This invention relates to the combustion of gaseous fuel in a rotary kiln during the calcination of carbonates. The purpose of the invention is to reduce the amount of nitrogen oxides formed during combustion of the fuel. Summary of the invention: it is necessary to supply steam to the flame continuously at a rate of 0.03-0.08 kg / m of gaseous fuel. Characteristic: the amount of NOX (mg / l) - 130 - 290. 1 table.

Description

Изобретение относитс  к пламенным печам - к сжиганию топлива во вращающихс  печах, работающих на производстве извести , доломитов и др,BACKGROUND OF THE INVENTION The invention relates to fiery furnaces — the burning of fuel in rotary kilns operating in the production of lime, dolomite, etc .;

Известен способ обжига карбонатов и других аналогичных материалов, заключающийс  в периодической подаче перегретого пара под давлением 3-6 эти в количестве 0,05 - 0,15 кг/1000 ккал тепловой нагрузки печи под факел.The known method of burning carbonates and other similar materials, which consists in the periodic supply of superheated steam under a pressure of 3-6 these in the amount of 0.05-0.15 kg / 1000 kcal heat load of the furnace under the flame.

Целью изобретени   вл етс  уменьшение количества оксидов азота.The aim of the invention is to reduce the amount of nitrogen oxides.

Пример. Перегретый пар непрерывно подают в зону факела в количестве 0,03 - 0,08 кг/м газового топлива.Example. Superheated steam is continuously fed to the flare zone in an amount of 0.03-0.08 kg / m of gaseous fuel.

Непрерывна  подача в факел уменьшает его среднюю температуру, что способствует уменьшению количества образующихс  оксидов азота. Также способствует снижению количества NOX в факеле микрозон с высокой температурой. Результаты представлены в таблице.Continuous feed to the torch reduces its average temperature, which helps reduce the amount of nitrogen oxides produced. It also helps to reduce the amount of NOX in the high temperature microzone plume. The results are presented in the table.
