Abstract

Система (1) охлаждения тяжелых шлаков, подходящая для использования совместно с камерой (2) сгорания, в частности, для больших расходов шлаков, полученных, например, из твердого органического топлива в установке для выработки энергии, при этом система (1) содержит транспортирующую ленту (31) для транспортирования тяжелых шлаков, приспособленную для размещения ниже камеры (2) сгорания, снабженную защитным кожухом (3) и имеющую транспортирующую поверхность (311), в которой имеются отверстия (9) для прохода охлаждающего воздуха, при этом транспортирующая поверхность (311) приспособлена для приема шлаков, полученных в камере сгорания (2), загруженных на транспортирующую поверхность, по существу, в виде непрерывного слоя; и средства охлаждения тяжелых шлаков, загруженных на указанную транспортирующую поверхность (311), при этом средства охлаждения включают по меньшей мере один секционированный участок (4), расположенный ниже указанной транспортирующей поверхности (311) и средства (11) принудительной подачи охлаждающего воздуха на указанный секционированный участок (4); при этом указанный секционированный участок (4) выполнен так, чтобы ограничить утечки подаваемого воздуха, а общее выполнение обеспечивает при работе системы прохождение охлаждающего воздуха, подаваемого на указанный секционированный участок (4), через указанные отверстия (9) в транспортирующей поверхности (311) и через слой шлака, загруженного на эту поверхность.A heavy slag cooling system (1) suitable for use in conjunction with a combustion chamber (2), in particular for high slag flows obtained, for example, from solid fossil fuel in a power generation plant, while the system (1) contains a conveyor belt (31) for transporting heavy slag, adapted to be located below the combustion chamber (2), equipped with a protective casing (3) and having a transport surface (311), in which there are holes (9) for the passage of cooling air, while the transporting surface (311 ) is adapted to receive the slags obtained in the combustion chamber (2), loaded onto the transport surface, essentially in the form of a continuous layer; and means for cooling heavy slags loaded on said transporting surface (311), wherein the cooling means include at least one sectioned section (4) located below said transporting surface (311) and means (11) for forced supply of cooling air to said sectioned section (4); while the specified sectioned section (4) is made so as to limit leaks of the supplied air, and the general design ensures, during the operation of the system, the passage of the cooling air supplied to the specified sectioned section (4) through the indicated holes (9) in the conveying surface (311) and through a layer of slag loaded onto this surface.
