Steam Boiler Questions and Answers

2019-12-18 · Steam Boiler Questions and Answers By Lars Josefsson. Boiler drum level control goes haywire The most common fault with a three-point level controller is the steam flow transmitter. Normally one part of the boiler is heated by means of a fuel oil burner and the other part is heated by the exhaust gases from a diesel engine.

Finding the Root Cause of Boiler Tube Failures

Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water

With a boiler thermostat, the older it is, the more likely it will be to develop a fault. An issue could be a temperature misreading or the boiler switching itself on and off. In this case, although a professional can clean and reconnect the thermostat, it would be wise to invest in a new, energy efficient boiler …

When warming up a steam boiler, open the boiler drum vent to prevent over-pressurization of the boiler during start-up. permit the release of corrosive dissolved gases, such as oxygen and carbon dioxide, from the boiler water. ensure a flow of steam through the superheater banks. keep a vacuum from forming in the drum, if the burner trips off.

Boiler controls help produce hot water or steam in a regulated, efficient, and safe manner. Combustion and operating controls regulate the rate of fuel use to meet the demand. The main operating control monitors hot water temperature or steam pressure and sends a signal to control the firing rate, the rate at which fuel and air enters the burner.

In the Frasch industry, steam boiler corrosion was an important difficulty. Since 1500 gallons of water are needed to produce one ton of sulfur, it was necessary to develop sea water resistant steam plants before off shore mining became possible (Brogdon (U.S.P. 2,937,624, 1960; Axelrad, U.S.P. 2,947,690, 1960).
