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.
The first edition of the Boiler and Pressure Vessel Code, known as the 1914 edition, was a single 114-page volume. It developed over time into the ASME Boiler and Pressure Vessel code, which today has over 92,000 copies in use, in over 100 countries around the world.

A boiler utilizing a standard burner with a 4:1 turndown can cycle as frequently as 12 times per hour or 288 times a day because the boiler must begin to cycle at inputs below 25% capacity. With each cycle, pre- and post-purge air flow removes heat from the boiler and sends it out the stack.

2. If the boiler/water heater is operated while the building An optimum site will be level, central to the piping system, close to a chimney or outside wall and have adequate fresh air for combustion. Ensure that the boiler/water heater is level from front to back and from side to side. Use metal shims to level the boiler/water heater.
ASME Code construction ensures high quality design, safety, third party inspection, and reliability, and accordingly bears the ASME Section IV “H” stamp. Premix Technology The burner utilizes “Premix” technology to mix both gas fuel and combustion air prior to entering the
Temporary air intakes such as open boiler room windows can be closed (and often are when persons in the boiler room are feeling cold), cutting off the boiler's air supply. When the combustion air supply is closed off, the fire starts to smoke as the air supply is exhausted. Incomplete combustion occurs and carbon monoxide is generated.

Meanwhile, the waste burned on the grate has undergone partial combustion. This produces carbon monoxide and nitrogen oxides (CO and NOx). As the products of combustion, or flue gas, move up through the furnace, they pass by an overfire air system, which injects the balance of the combustion air into the gas.
