Изобретение относится к способу сжигания черного щелока в котлах утилизации с получением паров, имеющих низкое содержание окисей азота (NOx). Изобретение характеризуется тем, что часть воздуха для сжигания добавляют как последнюю порцию на очень высоком уровне, так чтобы восстановительная атмосфера существовала в очень большой части котла в течение длительного периода времени, по крайней мере 3 - 5 сек. Изобретение также включает в себя котел утилизации для осуществления вышеуказанного способа.The invention relates to a method of burning black liquor in recovery boilers to produce vapors having a low content of nitrogen oxides (NO x ). The invention is characterized in that a portion of the combustion air is added as the last portion at a very high level, so that the reducing atmosphere exists in a very large part of the boiler for a long period of time, at least 3-5 seconds. The invention also includes a disposal boiler for carrying out the above method.
