Изобретение относитс  к области снижени  образовани  окислов серы в продуктах сгорани  и может быть использовано при сжигании сернистых углей.The invention relates to the reduction of the formation of sulfur oxides in combustion products and can be used in the combustion of sulfur coal.

Известны способы снижени  образовани  окислов серы в продуктах сгорани  высокосернистых топлив при сжигании мазута или угл  с торфом, содержащим гуматы кальци , распадающиес  при нагреве с выделением окислов, кальци , которые частично св зывают окислы серы 1.Methods are known for reducing the formation of sulfur oxides in the combustion products of high-sulfur fuels when burning mazut or coal with peat containing calcium humates, decomposing when heated, releasing calcium oxides, which partially bind sulfur oxides 1.

Однако заметное снижение выбросов окислов серы с дымовыми газами при сжигании угл  с торфом быть достигнуто лищь при присадке торфа в количествах, значительно превыщающих количество сжигаемого высокосернистого топлива, что неэкономично и требует фактически перевода предпри тий на торф.However, a noticeable reduction in emissions of sulfur oxides with flue gases when burning coal with peat can be achieved by adding peat in amounts that significantly exceed the amount of high-sulfur fuel that is burned, which is uneconomical and requires actually transferring the enterprises to peat.

Цель изобретени  - использование такой присадки к сжигаемым высокосернистым угл м , котора  бы обеспечила снижение образовани  окислов серы в дымовых газах при минимальных количествах присадки и высокой экономической эффективности.The purpose of the invention is the use of such an additive to burning sour coal, which would reduce the formation of sulfur oxides in flue gases with minimal amounts of additive and high economic efficiency.

Это достигаетс  использованием в качестве присадки карбонатосодержащих горючих сланцев. Содержащиес  в этих сланцах известн ки в процессе горени  разлагаютс  с выделением окислов кальци  и магни , которые обеспечивают св зывание части образующихс  при сжигании высокосернистых углей окислов серы. Получающиес  при этом сернокислые кальций и частично магний удал ютс  из газов в виде золы.This is achieved by using carbonate-rich shale as an additive. The limestone contained in these shales decomposes during the combustion process with the release of calcium and magnesium oxides, which bind some of the sulfur oxides formed during combustion of sour coal. The resulting calcium sulfate and partly magnesium are removed from the gases in the form of ash.
