Ladle Heating Device

Traditional ladle heating generally use a semi-open cover of open baking, the use of ordinary low-pressure burners, the use of high calorific value of fuel (natural gas), after combustion of high temperature flue gas (even flame) overflow from the ladle edge directly into the atmosphere, while heating the air cooling steel plate square tube around the ladle cover, in order to recover part of the waste heat. Due to the above structural characteristics, the baking time is long, the baking temperature of the ladle is low, mostly 600℃-1000℃, the temperature difference of the ladle is large, the thermal efficiency is extremely low, the fuel consumption is high, and the environmental pollution is serious.

Product Description

In combination with the latest research and development of oxygen combustion technology, we have developed a series of oxygen gas combustion processes and products, including a new type of ladle natural gas-oxygen combustion heating, as well as supporting oxygen and fuel flow control valve groups and combustion control systems.



Technological advantage

1) The heating temperature is high, up to 900~1200℃, and there are special requirements that can reach more than 1300℃.

2) Reduce emissions of pollutants (clean and complete combustion) and reduce exhaust volume (up to 70%);

3) Long residence time of flue gas in ladle, high heat transfer efficiency, fast heating rate;

4) Significant reduction in total nitrogen oxide emissions:

5) The flame length is controllable and the heat flow distribution is reasonable. Bag temperature difference is less than 30℃.

6) The nozzle has good material, good heat resistance and long service life.

7) Wide range of applicable fuels. Such as blast furnace gas, converter gas, coke oven gas, mixed gas, natural gas and so on.
