External oil hot blast furnace

Application: 

for cement, chemical industry, metallurgy-supporting coal mill, raw material mill (cement), cement mill, dryer etc.;

Working principle:

YR series hot air furnace (Patent No.200420016992.9) consists of fuel supply device, air supply device, combustion device, combustion chamber and thermal control system. All steel structure furnace combustion chamber furnace wall is composed of multiple different angle of steel umbrella ring set, there is a certain gap between each ring, the furnace outer wall is made of steel cylinder, the outer wall and combustion chamber furnace wall formed between a ring channel, the cold air enter through the ring channel, from the gap between the ring umbrella into the furnace mixes with the high temperature flue gas . The steel umbrella ring of the furnace inner wall is made of different steel based on the working temperature. 

Main Performance and features

★Reasonable Structure: full steel structure, with low energy consumption, low wear, light weight, small volume, short installation period, investment saving, simple maintenance, mobile and so on;

★ Easy to Use: all steel structure without refractory brick lining, no need preheating before starting the furnace, it can meet the heating requirements when switch-on, stop the furnace rapid cooling, without emergency chimney;

★ wide adaptability: combustible diesel oil, heavy oil, residual oil etc.;

★ High thermal efficiency: high efficiency atomization fuel nozzle, multiple air supply, combustion efficiency is higher than 99%; self-cooling and thermal insulation design, the furnace body outer wall temperature is low, and the thermal efficiency is more than 98%;

★ heating stability: the heating temperature is 100-1200℃ adjustable; the hot blast furnace load adjustment is flexible, can be controlled by fully automatic, manual way.
