Gasification - Wikipedia

Gasification is a process that converts biomass- or fossil fuel-based carbonaceous materials into gases, including as the largest fractions: nitrogen (N2), carbon monoxide (CO), hydrogen (H2), and carbon dioxide (CO2). This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in

Boiler (power generation) - Wikipedia

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.

How does high negative draft affect the solid fuel fired

Jan 01, 2021 · 01 Jan 2021. High negative draft in a solid fuel fired boiler carries away the unburnt fuel along with the flue gas. This leads to wastage of fuel. A draft is necessary in a boiler to ensure the flue gases are led to the chimney and to ensure a smooth exhaust. On the basis of the mechanism of generating the draft a boiler may be classified as a forced draft, induced draft or a balanced draft boiler.
