US4368677A - Pulse combustion system for boilers - Google …
Boiler fuel is exposed to a flow of pulsating hot gas and sonic energy from a pulse jet engine for classifying fuel particles with uniform size and moisture content. A second pulse jet engine directs a continuous flow of pulsating hot gas and sonic energy onto those surfaces of heat exchangers which are exposed to the boiler heating gas, for cleaning the heat exchanger surfaces.

Economizer - an overview | ScienceDirect Topics
In shell boilers with a working pressure of between 7 and 17 bar the temperature of the mass of water in the boiler is typically in the range of 170–210 C. Allowing for, say a temperature difference of 30–50°C between the exhaust gases and the water temperature, the boiler exit gas temperature cannot be economically reduced beneath about 200–260°C, dependent on the operating pressure.

Boiler control - Plant Services
2004/2/25 · Boiler drum-level control is critical. Too low a level may expose boiler tubes, which overheats and damages them. Too high a level may interfere with separating moisture from steam, which reduces boiler efficiency and carries moisture into the process or turbine. The drum-level controller maintains the level at constant steam load.
