Abstract
Настоящее изобретение относится к установке для извлечения и утилизации тепловой энергии больших расходов тяжелых шлаков, полученных в паровых котлах, работающих на твердом топливе, способной уменьшить конечную температуру удаленного шлака без повышения расхода воздуха, поступающего в дымоход парового котла, обычно установленного проектировщиками котла на уровне приблизительно 1,5% от общего расхода воздуха горения. Если расход воздуха, необходимый для охлаждения, превышает максимальную величину, допустимую для парового котла, система позволяет направлять избыточный воздух и возможные пары по воздуховоду для ввода воздуха в теплообменник воздух/дымовые газы, причем благодаря разобщению средств охлаждения, созданному самим шлаком. Указанным разобщением средств охлаждения в системе охлаждения управляют автоматически по сигналу температуры шлака, транспортируемого к месту выгрузки из установки. Если охлаждающего воздуха недостаточно для охлаждения шлака, то эффективность охлаждения может быть повышена за счет добавления распыленной воды.The present invention relates to an installation for the extraction and utilization of heat energy of high consumption of heavy slags obtained in steam boilers operating on solid fuels, capable of reducing the final temperature of the removed slag without increasing the air flow entering the flue of the steam boiler, usually set by the designers of the boiler at a level of approximately 1.5% of the total combustion air consumption. If the air flow required for cooling exceeds the maximum allowable for the steam boiler, the system allows excess air and possible vapors to be directed through the duct to introduce air into the air / flue gas heat exchanger, thanks to the isolation of the cooling means created by the slag itself. The specified decoupling of the cooling means in the cooling system is controlled automatically by the temperature signal of the slag transported to the place of unloading from the installation. If there is not enough cooling air to cool the slag, the cooling efficiency can be increased by adding atomized water.
