6. The potential use of wood residues for energy generation

Watertube boilers consist of tubes welded together in such a manner as to form complete walls enclosing the combustion chamber, through which flows the water to be heated. By virtue of its construction, the watertube boiler is almost exclusively used where steam pressures above ten kg/cm2 (12) are employed, especially in providing motive power to turbine-generators.

Combined Heat and Power | CHP | Cogeneration | Cogen

Combined heat and power (CHP) is the simultaneous cogeneration of electricity and heat. Cogeneration is a highly efficient form of energy conversion and using gas engines it can achieve primary energy savings of approximately 40% compared to the separate purchase of electricity from the electricity grid and gas for use in a boiler.

2020/9/18 · The heat exchange surfaces for hot water boilers must be in contact with water to prevent the heat exchange surface from overheating. Low level water sensors are required to ensure this. Fuel and air are controlled in concert, but the quantity of fuel delivered is a function of thermal input required to control the boiler temperature.

There the combustion, in air, of a fossil fuel such as oil, natural gas, or coal produces hot combustion gases that transfer heat to water passing through tubes in the boiler. The heat transfer to the incoming water (feed water) first increases its temperature until it becomes a saturated liquid, then evaporates it to form saturated vapor, and usually then further raises its …
