Description
Изобретение относитс к сжиганию топлива и может быть использовано на тепловых электростанци х.This invention relates to fuel combustion and can be used in thermal power plants.
Цель изобретени - повышение эконо мичности.The purpose of the invention is to increase the economy.
Способ сжигани твердого топлива в режиме жидкого шлакоудалени осуществл ют следующим образом.The method of burning solid fuel in liquid slag removal mode is carried out as follows.
При сжигании твердого топлива образуютс жидкий шлак и продукты сгорани , содержащие золу, котора после охлаждени продуктов сгорани улавливаетс и в количестве , равном 0,1-0,35 от количества шлака , смешиваетс с последним. Зола при смешении со шлаком расплавл етс , и из полученной смеси производитс восстановление содержащихс в шлаке и золе окис1213309When burning solid fuels, liquid slag is formed and combustion products containing ash, which, after cooling the combustion products, are captured and in an amount of 0.1-0.35 of the amount of slag, mixed with the latter. The ash, when mixed with the slag, melts, and the resulting mixture is used to reduce the oxide contained in the slag and the ash.
лов металлов до ферросплавов углеродом топлива.metal trapping to ferroalloys carbon fuel.
Пример 1. Кузнецкий уголь КЖ (зольность А 28%) сжигаетс в котле ТП-87Example 1. Kuznetsk coal QOL (ash content A 28%) is burnt in a boiler TP-87
при расходе топлива 30 т/ч. При коэффициенте улавливани шлака 0,15 и температурах Тн.ж. 1500 и Тв 1700°С 1 кг шлака способен расплавить 0,164 кг золы, что отвечает соотношению шлак:зола 1:0,164. При этом коэффициент улавливани щлака возрастает с 0,15 до 0,175 или на 2,5%. Пример 2. Шлаки волынских углей (А 30%, Тн.ж. 1270 С, Т. 1700°С), полученные при сжигании 30 т/ч угл на котле ТП-87, дают увеличение коэффициентаwith fuel consumption of 30 t / h. With a slag trapping coefficient of 0.15 and temperatures of T.N. 1500 and TV 1700 ° С 1 kg of slag can melt 0.164 kg of ash, which corresponds to the slag: ash ratio of 1: 0.164. At the same time, the grab-trapping coefficient increases from 0.15 to 0.175 or by 2.5%. Example 2. Slags of Volyn coal (А 30%, Tn.zh. 1270 С, T. 1700 ° С), obtained by burning 30 t / h of coal on the TP-87 boiler, give an increase in the coefficient
г улавливани шлака на 5,1% при соотношении шлак:зола 1:0,337. При этом объем перерабатываемого шлака возрастает на 0,45 т/ч или на 2925 т/г.g slag trapping by 5.1% with a slag: ash ratio of 1: 0.337. The volume of the processed slag increases by 0.45 t / h or by 2925 t / g.
