Abstract

Настоящее изобретение относится к дополнительной системе (1) охлаждения для сухого удаления большого потока плотной золы, получаемой в бойлерах (100), в которых используется твердое топливо, пригодное для уменьшения температуры золы. Система содержит экстрактор с металлической лентой (2), собирающий золу, которая оседает в нижней части бойлера (100), систему (3) дробления, предназначенную для увеличения поверхности теплообмена материала, один или больше металлических конвейеров (4, 6), выполняющих функцию охлаждения путем подачи потока воздуха в противотоке, протекающего через транспортируемую золу, установленное в линию устройство (5) охлаждения, выполняющее функцию многократного ввода в контакт золы дополнительным противотоком воздуха для увеличения возможного теплообмена без необходимости увеличения потока воздуха, поступающего в камеру сгорания. Такой дополнительный воздух может быть направлен предпочтительно в место перед нагревателем воздуха или может быть выведен в атмосферу после удаления мелких частиц.The present invention relates to an additional cooling system (1) for the dry removal of a large flow of dense ash produced in boilers (100) using a solid fuel suitable for reducing the temperature of the ash. The system contains an extractor with a metal belt (2) that collects ash that settles in the lower part of the boiler (100), a crushing system (3) designed to increase the heat exchange surface of the material, one or more metal conveyors (4, 6) that perform the cooling function by supplying a counter-current air flow flowing through the transported ash, an in-line cooling device (5) that performs the function of repeatedly introducing additional air counter-current into the ash contact to increase the possible heat exchange without the need to increase the air flow entering the combustion chamber. Such additional air may preferably be directed to a location upstream of the air heater, or may be vented to the atmosphere after fine particles have been removed.
