Description
Изобретение относитс к способу предотвращени коррозии и загр знений тепловоопринимающих новерхностей энергетических установок с помощью присадок, содержащих марганец и вводимых в топливо или дымовые газы.The invention relates to a method for preventing corrosion and contamination of heat-receiving surfaces of power plants using additives containing manganese and introduced into fuels or flue gases.
Известные присадки на основе соединений марганца представл ют собой органорастворимые соединени марганца или неводорастворимые соединени типа окисей и карбонатов, которые требуют специального производства.Known additives based on manganese compounds are organic manganese compounds or non-soluble compounds such as oxides and carbonates, which require special production.
Дл расщцрени сырьевой базы по предложенному способу в качестве присадки используют марганцевый щлам, образующийс при окислении углеводородпого сырь на катализаторе , содержащем марганец, например в процессе окислени парафина на катализаторе . Присадку ввод т в весовом соотношенниTo dissolve the raw material base of the proposed method, manganese gaps are used as an additive, resulting from oxidation of the hydrocarbon feedstock on a catalyst containing manganese, for example, in the process of paraffin oxidation on the catalyst. The additive is administered in a weight ratio of
0,0003 - 0,1,0.0003 - 0.1,
ОхOh
где Мп - содержание марганца в щламе, ST - содержание серы в топливе.where Mn is the manganese content in schlama, ST is the sulfur content in the fuel.
В марганцевый щлам могут быть введены также соединени одного или нескольких металлов , например магни , алюмини , железа, меди, что улучшает структуру отложений, образующихс на поверхност х пагрева. Соединени указанных металлов целесоооразно вводить в виде водорастворимых соединений или соединений, образующих стойкие эмульсии (суспензии) в воде. Предложенна присадка, в которой марганец находитс в ионной форме , имеет реакционную способность в 5-20 раз вьппе, чем известные присадки. Присутствие же в марганцевом шламе низкомолекул рных органических кислот, спиртов, альдегидов и кетонов сокращает врем предпламепных реакций в 2-10 раз, что сокращает размер 11 факела и повышает температуру горени .Compounds of one or more metals, such as magnesium, aluminum, iron, copper, can also be introduced into the manganese gaps, which improves the structure of the deposits formed on the surfaces of the flue. Compounds of these metals are expediently administered in the form of water-soluble compounds or compounds that form stable emulsions (suspensions) in water. The proposed additive, in which manganese is in ionic form, has a reactivity of 5 to 20 times more than the known additives. The presence in the manganese sludge of low molecular weight organic acids, alcohols, aldehydes and ketones reduces the time of pre-flame reactions by 2-10 times, which reduces the size of the torch 11 and increases the combustion temperature.
Предложенна присадка может быть введена в топливо перед его сжиганием, в воздух, поступающий в камеру сгорани , в объеме камеры сгорани , в газовый тракт, на участках, предшествующих зонам активной коррозии и загр знени тепловосприпимающих ловерхпостей .The proposed additive can be introduced into the fuel before it is burned, into the air entering the combustion chamber, into the volume of the combustion chamber, into the gas path, in the areas preceding the zones of active corrosion and contamination of heat-receiving materials.
