A laser beam delivery system is disclosed, which allows transmission of high-power infrared light through a hollow core photonic band gap (HC-PBG) fiber made of non-silica-based glass. In this system, the infrared beam first passes through input coupling optics which focus the beam onto the hollow core of the HC-PBG fiber. In front of the input end of the HC-PBG fiber, there is provided a mask with a hole aligned with the hollow core, and the infrared beam first passes through this hole before entering the hollow core of the HC-PBG fiber. This protects the photonic band gap structure from being damaged by the beam. After passing through the HC-PBG fiber, which may be from one to several hundred meters in length, the infrared beam exits at the output end of the fiber and passes through output coupling optics which collimate and focus the beam onto a desired target. The various components of the system may be water cooled during the operation or subjected to a gas purge to prevent condensation or gas ionization.

The invention relates to a method and a system for combining solar energy thermal power generation with biomass power generation. When the method is used for generating electricity in the daytime (a fine day), one path of heat transfer oil heated in a heat collection field passes through a heat exchanger to ensure that counter-flow water is heated up into superheated steam at the temperature of between 360 and 380 DEG C; and the other path of the heat transfer oil heated in the heat collection field passes through the heat exchanger to heat up a fused salt so as to perform energy storage. The water heated in a water cooled wall of a biomass boiler is changed into steam which enters a steam header and a steam-water separator, then is heated to the temperature of between 535 and 545 DDEG C after being sent into a super-heater of the boiler together with the steam at the temperature of between 360 and 380 DEG C, and then is supplied to a steam turbine to drive a generator to finish the power generation process. During receiving electric valley adjustment, the biomass boiler maintains the minimum stable combustion state. The self power generation of the method and the system can be used for supplying electricity to an electric heater in a fused salt heat storage system to heat the fused salt and perform secondary energy storage for a fused salt heat tank. During the night, or when a solar energy condition is not good, the heat energy stored in the fused salt is released by the heat exchanger to generate electricity.
