Abstract

The invention provides a biomass feeding system with double-bias type rotary feeding valves and a feeding method. The existing biomass feeding system has two problems of blockage of a feeding system and backflow of high-temperature flue gas. The biomass feeding system comprises the first-stage bias rotary feeding valve (1) and the second-stage bias rotary feeding valve (3). An outlet of the first-stage bias rotary feeding valve is communicated with an inlet of the second-stage bias rotary feeding valve, and a pressure balance pipe (2) is arranged at a communication position (9). The first-stage bias type rotary feeding valve and the second-stage bias type rotary feeding valve are both composed of a housing (10) and a rotary discharger (8) which is rotationally connected to the interior ofthe housing. Each rotary discharger comprises a central shaft and a set of rotating paddles (5) fixed on the central shaft, and flexible sealing sheets (4) are fixed at one ends, far away from the central shaft, of the rotating paddles. The invention relates to the biomass feeding system with double-bias type rotary feeding valves and the feeding method.

Description

Technical field: [0001] The invention relates to a biomass feeding system and a feeding method of a double offset rotary feeding valve. Background technique: [0002] Biomass power generation technology is an advanced energy-saving and environmentally friendly power generation technology. According to the technical route, it is divided into biomass direct combustion power generation technology, biomass co-combustion power generation technology and biomass gasification power generation technology. The stability and safety of the biomass feeding system have high requirements. If there are problems such as blockage and high-temperature flue gas backflow in the biomass feeding system, it will not only affect the operation of the biomass incinerator or biomass gasifier, but also Cause the feeding system to catch fire or even explode and other safety accidents. [0003] There are still two problems in the existing biomass feeding system: (1) Blockage of the feeding system: most b...
