Under increasingly strict environmental policies, domestic red brick kilns adopt a "coal to gas" or "coal to oil" technological transformation plan in combination with the sintering process of standard bricks or porous bricks. The "coal to gas" plan has been elaborated earlier, and the "coal to oil" measures are discussed here.
Coal to oil conversion refers to the process of completely using diesel, heavy oil, and alcohol based fuels (environmentally friendly oil) as heat sources and sintering red bricks without internal combustion. Generally, diesel sintering process is used abroad, and there are attempts to use alcohol based fuel oil in China.
1. As the calorific value of environmentally friendly oil is generally between 8000 to 10000 kcal/kg, the calorific value can be adjusted by the fuel oil manufacturer. The environmentally friendly oil burner is generally arranged on both sides of the furnace wall or on the furnace top. The power of diesel heavy oil burners is generally between 100000 to 200000 kcal/tube, and the fuel quantity is designed according to 10-20 kg/tube. The combustion tube design length of the burner varies from 600-1500mm, and can be customized with an extended type. The ignition method is selected as manual or automatic, and the high-precision UV probe designed for flame detection monitors the real-time combustion status of the flame. Once the flame is extinguished, the system will generate an audible and visual alarm and immediately cut off the fuel valve.
2. Sintered standard bricks may experience the phenomenon of "incomplete burning", uneven heating inside and outside the standard bricks, affecting the sintering quality. The sintering effect of porous bricks is better than that of ordinary standard bricks.
3. To prevent the phenomenon of "pouring", please feel free to call (WeChat synchronization) at 13849187223 for more details.
4. In the design and construction of oil tanks and pipelines, if heavy oil fuel is used, an intermediate buffer tank and electric heating equipment need to be added to improve the fluidity of heavy oil and fully mix with combustion air for combustion.
