Figure 2 shows a photo of a burner retrofit for a 50,000-lb/hour, 150-psi saturated steam boiler with a new burner assembly with combustion safety controls.

Get A QuoteThe control strategies now used in modern industrial boiler systems had their beginnings on shipboard steam propulsion boilers. When boilers operated at low pressure, it was reasonably inexpensive to make the steam drum large. In a large drum, liquid level moves relatively slowly in response to disturbances (it has a long time constant).

If the control is in a low water condition when there is an interruption of power, the control will remain in a low water condition when power is restored.

Get A QuoteThis type of control can be fitted to any size boiler, but should always be fitted to boilers rated at over 10 000 kg/h. Advantages of a modulating control system: The boiler is even more able to tolerate large and fluctuating loads.
Get A QuoteThree-element control is a must with multiple boilers sharing the same feedwater header and supply system. This feedwater system experiences variations in feedwater flow with two or more boilers online. Types of Sensors Float control. Float control is the simplest form of level measurement.

Get A QuoteJan 30, 2018 · Steam boilers are very common in industry, principally because steam power is so useful. Common uses for steam in industry include doing mechanical work (e.g. a steam engine moving some sort of machine), heating, producing vacuums (through the use of steam ejectors), and augmenting chemical processes (e.g. reforming of natural gas into hydrogen and carbon dioxide).
