Description

ры в огарке, Хонаентраци  502Ог 12 до 16,3% и конценграци  осгагочного кислор{ да до 5%), его поддерживают с коррекцией по составу отход щего газа.Butts in the cinder, the concentration 502Og 12 to 16.3%, and the concentration of the oxygen from the oxygen (yes to 5%), it is supported with a correction in the composition of the exhaust gas.

Характеристика способа Линейно св зана с концентрацией сернистого ангидрида.. Мо к но поддерживать необходимую область обжига , использу  и концентрацию SOg в обжиговом газе:Characterization of the method is linearly related to the concentration of sulfur dioxide. Mo to maintain the required firing area using the concentration of SOg in the kiln gas:

до концентрации 14.2-14,3% SOg-окислительна  область; концентраци  14,3-14,7% SCfe- переходна  область} |выше концентрации 14,7% 50 -магнетизирующа  область.to a concentration of 14.2-14.3% SOg-oxidative region; a concentration of 14.3-14.7% SCfe-transition region} | above a concentration of 14.7% 50-the magnetization region.

Лабораторные исследовани  показали, что дл  получени  огарка в виде магнетита в печи кип щего сло  КС-2ОО, производитель ностью 8 тн/м в сутки температура слой Laboratory studies have shown that to obtain an calcine in the form of magnetite in a KS-2OO fluidized bed furnace, with a capacity of 8 tons / m per day, the temperature is

составила 680-690 С, температура отход щего газа-8О5-810 С, т.е. интервал разности составил 105-110 С, но область существовани  магнетизирующего обжига была тире и составила 9О-1ЗО С. Сера в огарке (магнетите)после циклона не превышала 1%amounted to 680-690 C, the temperature of the exhaust gas-8O5-810 C, i.e. the difference interval was 105-110 ° C, but the area of the existence of magnetising roasting was a dash and was 9O-1ZO C. Sulfur in the calcine (magnetite) after the cyclone did not exceed 1%
