Method and system for power generation

A method of power generation, comprising the following steps:

• 1) igniting a biomass boiler comprising a boiler drum when a water level of the boiler drum reaches a preset water level;
• and starting a turbonator unit according to an operating procedure of a biomass boiler power plant;
• 2) starting a solar concentrating collector;
• measuring a water temperature t3 at a water outlet main of the solar concentrating collector;
• opening a second control valve arranged between the water outlet main and the boiler drum when t3 ≧95° C., and opening a third control valve to supply water to a solar collector tube;
• introducing the water into the boiler drum;
• adjusting the water supply to the solar collector tube to maintain t3≧95° C.;
• and maintaining the water level of the boiler drum, a vapor pressure, and a vapor temperature at a vapor outlet of the biomass boiler at rated values and maintaining a steady operation of the turbonator unit by self-regulating of a control system of the turbonator unit;
• 3) closing the second control valve of the water outlet main and the third control valve to prevent water in the solar collector tube from running and to maintain the water in a heat preserving and inactive state if the water supply to the solar collector tube is adjusted to a lowest value while the water temperature t3 at the water outlet main of the solar concentrating collector detected by the turbonator unit decreases and t3<95° C.;
• turning the turbonator unit into a thermal power generation mode;
• increasing a fuel input into the biomass boiler by self-regulating of the control system of the turbonator unit to maintain the vapor pressure and the vapor temperature at the vapor outlet of the biomass boiler at rated values and to maintain the steady operation of the turbonator unit;
• 4) opening a first control valve arranged between the water outlet main of the solar concentrating collector and a water supply tank if the water temperature t3 at the water outlet main of the solar concentrating collector continues decreasing and when t3=5-9° C.;
• opening a bleed valve to drain room temperature water from the solar collector tube into a desalting water tank;
• opening a drain valve to remove remaining water from pipes;
• introducing compressed air via an opening of an exhaust valve into all pipes until no water remains;
• maintaining the solar concentrating collector and pipes at an anhydrous and antifreezing state;
• and turning the turbonator unit into a biomass boiler power generation mode;
• and
• 5) repeating step 1) if the water temperature in the solar collector tube increases and t3≧95° C. due to a recovery of a solar radiation;
• supplying water to the biomass boiler;
• and decreasing the fuel input into the biomass boiler by self-regulating of the turbonator unit.
