Abstract: A liquid fuel burning torch system maintains fuel within one or more torches by pumping fuel from a central reservoir to the torches via a plumbing system. The torches can be extinguished by reversing the flow of the fuel in the plumbing system, for example by reversing a pumping direction of the pump, switching pumps, or actuating flow reversal valves. The torches can include remotely controlled torch igniting mechanisms, wireless access for remote torch monitoring and/or control, and/or heat sensors for determining whether the torch is burning. The torches can include fuel overfill prevention (FOP) valves. A flow of fuel through the FOP valves can be directed so as to avoid impinging on plugs of the FOP valves. The FOP valves can include check valves that allow fuel to be drained from the torches even when the FOP valves are closed.

Abstract: A control method for optimizing generated power of a solar-aided coal-fired power system under off-design working conditions sets maximizing generated power without changing main steam flow rate as a control goal. A solar-coal feedwater flow distribution ratio is adjusted to adjust water flow rate heated by a solar heat collection system, so as to achieve the control goal. Control steps include reading relevant information; calculating the water flow rate range heated by the solar heat collection system, and an applicable solar-coal feedwater flow distribution ratio range; establishing a correspondence between the generated power and the solar-coal feedwater flow distribution ratio within this range; selecting a solar-coal feedwater flow distribution ratio corresponding to the maximum generated power; and adjusting the water flow rate entering the solar heat collection system to an optimized value. The present invention can flexibly control the solar-coal coupling and improve the economy.
