BOILER CONTROL SYSTEMS THEORY OF OPERATION

The purpose of any boiler control system is to provide safe, efficient operation of the boiler at the desired output without the need for constant operator supervision. This means that the combustion process inside the furnace must be controlled as well as -: the steam conditions at the boiler outlet.

Apr 04, 2019 · The control scheme can easily interface with an external Burner Management System (BMS). A typical BMS sends four signals to the combustion controls: boiler trip, purge, light-off, and release-to-modulate. The boiler trip signal tells the boiler controls to close the fuel valve. The purge signal causes the boiler controls to open the FD fan damper.

Oct 31, 2019 · Its purpose is to influence the flow rate of water into the boiler, throttling the water flow more or less as determined by controller. This particular type of control valve uses a large diaphragm and a large spring to move the valve further open with more signal pressure and

Procidia Control Solutions Boiler Control Overview

The boiler control system manipulates the firing rate so that the supply of steam remains in balance with the demand for steam over the full load range. In addition, an adequate supply of feedwater must be maintained, as must the correct air/fuel mixture for safe, economical combustion. In the following sections, boiler control subsystems

Apr 11, 2015 · Steam pressure and load control Pressure control in a single boiler is achieved by adjusting the firing rate so that the steam generation rate matches the steam flow rate at the desired pressure. The downstream users will largely determine the steam flow extracted from the boiler so that the boiler will operate in load following mode if it is adjusted to maintain the pressure at the drum or alternatively at the load entry point such as the steam header or turbine
