Steam Boiler Questions and Answers

Before you start raising the level in the boiler you have to find out if any part of the furnace walls has been overheated. If you raise the level over a glowing steel-wall then the boiler might produce more steam than the safety valves can handle and a nasty explosion would be the result.

Boiler (power generation)

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Consulting - Specifying Engineer | Case study: School boiler

Condensing boilers operate most efficiently when they are operating in condensing mode, which generally occurs when a boiler’s return-fluid temperature is at or below 130 F. In the case of the Beveridge Middle School, the boiler system added heat to the heat pump water loop, which was designed to be maintained between 60° and 70°F during the heating season.

A quick guide to condensate recovery

The lower the feedwater temperature, the more heat, and thus fuel needed to heat the water, thereby leaving less heat to raise steam. Boiler feedwater quality: Condensate is distilled water, which contains almost no total dissolved solids (TDS). Boilers need to be blown down to reduce their concentration of dissolved solids in the boiler water.
