What Do We Control Mill Outlet Temperature

Apart from this temperature control, there is another automatic control loop that is unique to ball-tube mills. The differential pressure across the mill is maintained at a constant pressure to ensure enough raw feed storage capacity inside the mill. The automatic DP control

Why Economizer and Air Pre-Heaters are Provided in

When air pre-heater is not provided the boiler efficiency will be around 74 only. Thus we can conserve about 20 extra fuel when we provide both economizers and air pre-heaters in boilers. Economizer. The feed water from the high pressure heaters enters the economizer and picks up heat from the flue gases after the low temperature superheater.

How to Run a Coal Fired Boiler at the Best Efficiency

Pulverized coal fired boilers the total losses account to about 12 to 14 . Roughly 50 of the losses can be tuned to the optimum and the other 50 is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also ...
