Boiler Basics Part 1 - Types and Components - HVAC School
2017/10/26 · A boiler is defined as a fuel-burning apparatus or container for heating water, in particular. The "in particular" part is thrown in there because many boiler systems heat a fluid other than water: glycol, oil, and process chemicals, to name a few. But, to keep things fairly simple, we will stick with water. So, your basic boiler burns a

Boiler Sizing - Heating Help
2009/7/16 · When steam heating was new, back at the turn of the 19th century, coal was the fuel of choice. It burned hot, and it burned long. A good coal-fired boiler would stay lit for eight to 10 hours on a load of coal. Those early boilers contained cast iron grates that were similar to what you have in your barbeque, but much thicker and far sturdier.

What Is Steam Boiler?- Definition, Working, and Types - …
A steam 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.
