Abstract

Изобретение относитс  к устройствам дл  сжигани  топлива, может быть использовано в топках котлов и других топ- ливоиспол ьзу ющих агрегатах и позвол ет повысить эксплуатационную надежность при снижении образовани  NOX При работе горелки охлаждающа  среда (вода или пар) может подаватьс  как по зазору 6, так и по трубе 12 в топку в корень факела, что снижает образование NOx 4 илThe invention relates to devices for burning fuel, can be used in furnaces of boilers and other fuel-utilizing units and allows to increase operational reliability while reducing the formation of NOX. During the operation of the burner, cooling medium (water or steam) can be supplied and through pipe 12 to the firebox to the root of the torch, which reduces the formation of NOx 4 or
