Evaluation of the condensation behavior of lead and zinc in BFB combustion of recovered waste wood

The chemistry of lead and zinc in the bubbling fluidized bed combustion of recovered waste wood (RWW) was studied based on advanced thermodynamic equilibrium calculations. The condensation behavior of zinc and lead compounds in different parts of the boiler was evaluated, and the dependence of the...

Modelling and simulation of CO2 (carbon dioxide) bottoming cycles for offshore oil and gas installations at design and off-design conditions

Improved energy efficiency is an issue of increasing importance in offshore oil and gas installations. The power on offshore installations is generated by gas turbines operating in a simple cycle. There is an obvious possibility for heat recovery for further power generation from the exhaust heat...
