Abstract: An oxy-combustion boiler unit is disclosed which includes a furnace for combusting fuel and for emitting flue gas resulting from combustion. The furnace has first, second and third combustion zones, and an air separation unit for separating oxygen gas from air and providing a first portion of the separated oxygen to a first oxidant flow, a second portion to a second oxidant flow, and a third portion of the separated oxygen gas to the first, second, and third zones of the furnace. A controller can cause the separated oxygen gas to be distributed so that the first and second oxygen flows have a desired oxygen content, and so that the first, second, and third zones of the furnace receive a desired amount of oxygen based on a combustion zone stoichiometry control.

Abstract: The molten salt solar tower system 100 is provided for controlling molten salt temperature in a solar receiver 130 for effective operation of the system 100 while without degrading physical properties of molten salt. The system 100 includes two circuits, first 140 and second 150. The first circuit 140 is configured to supply relatively cold molten salt in the solar receiver 130 for heating, and the second circuit 150 is configured to supply a predetermined amount of the relatively cold molten salt in the first circuit 140, as and when the temperature of the relatively hot molten salt circulating through the solar receiver 130 exceeds a predetermined set temperature value thereof.
