The History of the Steam-Generating Boiler and Industry - Insulation Outlook Magazine

The steam-generating boiler's roots go back to the late 1700s and early 1800s with the development of the kettle-type boiler, which simply boiled water into steam. The water was placed above a fire box and then boiled into steam. It wasn't until around 1867, with the development of the convection boiler, that the steam-generating industry

Boiler Efficiency and Combustion | Spirax Sarco

The usual arrangement is to have a fuel oil supply available on site, and to use this to fire the boiler when gas is not available. This led to the development of 'dual fuel' burners. These burners are designed with gas as the main fuel, but have an additional facility for burning fuel oil.

6. The potential use of wood residues for energy generation

The necessity of a larger-sized boiler, together with the need for waste handling plant involves up to 1.5 to 4 times the investment cost of oil fired package boilers. As indicated in Table 9, combustion efficiencies of 65 to 75 percent may be expected when burning wood waste, compared to 80 percent obtained from gas or oil fired units.
