Industrial Combustion Boilers
PROCESS AND TECHNOLOGY STATUS – Combustion boilers are widely used to generate steam for industrial applications and power generation. While all kinds of energy sources fossil fuels, biomass, nuclear and solar energy, electricity can be used to generate heat and steam, the scope of this brief is limited to combustion boilers using fossil fuels and biomass. Boilers can be grouped into two broad ...
متن کاملOverview of Coal Ash Deposition in Boilers
The management of coal ash in utility boilers continues to be one of the most important fuel property considerations in the design and operation of commercial boilers. The behavior of mineral matter in coal can significantly influence furnace sizing, heat transfer surface placement, and convection pass tube spacing. Ironically, many of the more reactive, low rank U. S. coals must have larger fu...
متن کاملThe Protection of Boilers from Sugar
Sugar contamination of boiler feedwater by smallcontinuous traces is not as serious as that from large 'slugs' which frequently find their way into the boilers. Reference is made to several incidents of sugar contamination in boilers to showthat the most commoncauses are a malfunction of the feedwater system or its mismanagement, and to show that the method of sugar detection is seldom at fault...
متن کاملOnline Mass Flow Prediction in CFB Boilers
Fuel feeding and inhomogeneity of fuel typically cause process fluctuations in the circulating fluidized bed (CFB) process. If control systems fail to compensate for the fluctuations, the whole plant will suffer from fluctuations that are reinforced by the closed-loop controls. This phenomenon causes a reduction of efficiency and lifetime of process components. Therefore, domain experts are int...
