Abstract

Горелка с подачей топлива сверху, работающая на твердом топливе, таком как стружка или уголь, которая включает в себя камеру сгорания (2), ограниченную снизу колосниковой решеткой (3), воздушный короб (14) горелки, соединенный с камерой сгорания и предназначенный для не сгоревших газов, и средства подачи первичного и вторичного воздуха. Отличительными признаками является то, что решетка (3) может вращаться в горизонтальной плоскости и перемещаться по вертикали для изменения объема камеры сгорания (2), а также то, что поддающийся ограничению ввод (16) для вторичного воздуха и демпфер (13), оборудованный контролируемым вводом для вторичного воздуха (15), размещаются в канале (12), соединяющем камеру сгорания и воздушный короб горелки, а также наличие управляемого вентилятора (21) для подачи воздуха для горения. Способ применения включает в себя понижение производительности путем уменьшения скорости вращения вентилятора (21) с последующим дросселированием канала (12), соединяющего камеру сгорания и воздушный короб горелки, с уменьшением подачи вторичного воздуха, уменьшение скорости вращения решетки (3) и закрытие отверстия (23) для продувочного воздуха.Международная заявка была опубликована вместе с отчетом о международном поиске.A burner with a fuel supply from above that runs on solid fuel, such as shavings or coal, which includes a combustion chamber (2), bounded below by the grate (3), an airbox (14) of the burner connected to the combustion chamber and not burnt gases, and means of supplying primary and secondary air. Distinctive features are that the grill (3) can rotate in a horizontal plane and move vertically to change the volume of the combustion chamber (2), as well as the restrictive lead in (16) for secondary air and the damper (13) equipped with controlled an inlet for secondary air (15), are placed in the channel (12) connecting the combustion chamber and the burner air duct, as well as the presence of a controlled fan (21) for the supply of combustion air. The method of application includes reducing performance by reducing the fan speed (21), followed by throttling the channel (12) connecting the combustion chamber and the burner air duct, reducing the secondary air supply, reducing the grid rotation speed (3) and closing the hole (23) for purge air. The international application was published along with an international search report.
