Section 23 52 33 - WATER-TUBE BOILERS

In 1905, the Grover Shoe Factory boiler exploded, collapsing the building and engulfing it in flames. Fifty-eight people were killed and 150 more injured. This event led to the development of safety laws and a national code for the safe operation of steam boilers. The CB-Hawk boiler management control system (''Figure 1'') combines the functions of

The burner will modulate between low and high firing rates depending on the steam pressure inside the boiler and where the modulation control is set. If the boiler setpoint is 80 PSI and the pressure in the boiler is 81 PSI, the modulation control should be sending a signal to the burner to drive to a lower firing rate if it is not already in

Methods of Detecting Water Level in Steam Boilers. On a steam raising boiler there are three clear applications for level monitoring devices: Level control - To ensure that the right amount of water is added to the boiler at the right time. Low water alarm - For safe boiler operation, the low water alarm ensures that the combustion of fuel does

*the boiler is concerned, but they are basically independent systems. They will, therefore, be discussed separately here. 2.2 Burner Control Systems It is the responsibility of the burner control system to supply air and fuel to the furnace in the correct proportions to meet the steam demand. It is important that the correct air to fuel ratio

FLAME SAFEGUARD CONTROLS IN MULTI-BURNER ENVIRONMENTS Figure 5: Schematic control diagram of automatic oil-fired unit, steam atomized Large capacity oil burners use two steps to combust the oil — atomizing and vaporization. Vaporization converts oil from the liquid to vapor by application of heat at the flame-front.

Burner Management and Combustion Controls - Indeck Power

Excess air can also produce excess NO x in some burners. So we want to control O 2 at its ideal amount for the load. The burner manufacturer should provide an O 2 trim SP curve – this should be plugged into a PWC with the output running through a bias station (always in auto!) to set the SP of the O 2 trim PID loop. Operators should NOT have the option to set the O2 Trim SP – they can put the loop in manual, …
