Overloading of coal-fired heat transfer oil furnaces

4.6MW coal-fired heat transfer oil furnace: oil outlet temperature is 242°C, oil return temperature is 230°C, pressure difference is 0.2 MPa, and coal consumption is 1 ton per hour. The temperature of the heating equipment in the workshop fails to rise – seeking advice from experts.
Adjust the blast air, exhaust air, and grate to increase the furnace temperature.
Your heat transfer oil has a temperature difference of only 12 degrees, so the heating speed of the thermal equipment in the workshop is naturally slow; it’s ideal for this purpose to have a temperature difference of 30 degrees. In other words, the oil outlet temperature of the heat transfer oil furnace needs to be increased.
Human intervention cannot create a large temperature difference; the smallest value is only 5-6 degrees
There’s no other way; we have to increase the level of management.
Of course, the temperature difference is also periodic; once the temperature of the heating equipment reaches the process temperature, the temperature difference decreases.
Is it possible to increase the outlet temperature of the heat transfer oil?
