What are the main factors that affect the output of thermal oil heater?

1) The insufficient heating surface. In the process of retrofit design or improvement, increase the heating surface.

2) The particle size of the fuel is large, the screening characteristics do not meet the requirements, the material concentration in the suspension section is low, and the heat transfer coefficient is small, which makes the output unable to go up, or shows that the bed temperature is high and coal cannot be added. The solution is to improve the fuel preparation system and control the particle size of the fuel.

3) The low speed of fluidized bed makes the whole circulation insufficient. If the fan performance is poor, it should be adjusted. If the boiler air leakage is serious, it should be stopped.

4) The efficiency of the separator is low, and the material circulation is not enough.
