The aim of this work is the parallel solution of large 3D-CFD problems concerning the numerical description of turbulent combustion and pollutant formation processes in coal-fired utility boilers. The in-house developed multi-domain CFD code AIOLOS for quasi-stationary, weakly compressible, turbulent reacting flows is used. The code is based on a conservative finite-volume formulation with a co...

Vanadium pentoxide is used as a catalyst and a ferrovanadium alloy ingredient in automotive steels and in jet engines and airframes. In addition, vanadium is found in fuel oils. Thus, occupational exposures to vanadium pentoxide and trioxide may occur during the cleaning of oil-fired ship boilers, and from oil-fired power station boilers. Occupational exposure to vanadium pentoxide induces gree...

Wind power generation reduces our reliance on fossil fuels and can thus reduce environmental pollution. However, rapid wind power development has caused various issues related to power grid restructuring. A high proportion of the generating capacity of northeast China is based on combined heat and power (CHP), whose inflexible response to the peak regulation of power grids hinders the ability t...

One of the main challenges using biofuels, such as pellets or wood chips in domestic boilers, is slagging and fouling risks associated to process, which could damage boiler limit its efficiency. The prediction sintering biomass combustion essential establish biofuel quality standards, minimize their harmful effects. In this work, we analysed chemical composition 40 woodchips samples from differ...

It has long been recognized that combined heat and power (CHP) generation can achieve higher end-use efficiencies than conventional systems. By generating electricity at the point of use and utilizing the co-produced heat, CHP generators can achieve net efficiencies in excess of 80%. This nearly doubles the efficiency of our current system, in which large centralized power plants provide electr...

Oxyfuel-firing of a steam boiler is a low risk high-efficiency technique for CO2 capture in a power plant. Oxyfuel-firing can be readily adapted to a new power plant or to retrofit applications. Development and design of pulverized coal and circulating fluidized bed oxyfuel boilers and balance of plant equipment have been conducted to identify the required specific features, which will maximize...

Generally Pressure process plant should be controlled in various applications such as Power plants, Chemical Industries, especially in boilers. There are controllers like PID, Model predictive controller, Fuzzy controller, and intelligent controller are used to control the pressure process. Here, the sliding mode controller is implemented to control and observe the pressure process, and then th...
