The invention relates to a biomass fuel feeding system, and belongs to the field of biomass combustion equipment. The system comprises a feeding subsystem, a water cooling subsystem and a fireproof subsystem which are connected in sequence; the feeding subsystem is used for receiving biomass fuel and pushing the fuel into an incineration hearth; the feeding subsystem comprises a feeding device, a distributing device, a storing device, a feeding device and a material level monitoring device; movable parts in the feeding subsystem are driven through hydraulic drive; the movable parts comprise a sealing device and a feeding device; the water cooling subsystem is used for cooling and protecting a part structure connected with the hearth; and the fireproof subsystem is used for preventing the biomass fuel from catching fire and burning at receiving, storing and feeding parts, and is provided with a fireproof spraying system and a temperature measuring device. The thermal radiation influence of biomass fuel on the feeding device is avoided; and the biomass fuel is prevented from being burnt in the feeding device.
Description
technical field [0001] The invention belongs to the field of biomass burning equipment and relates to a biomass fuel feeding system. Background technique [0002] Biomass energy is a kind of renewable energy. It is the energy form of solar energy stored in biomass in the form of chemical energy. The energy carried by biomass is directly or indirectly derived from the photosynthesis of green plants and can be converted into conventional energy. solid, liquid and gaseous fuels. There are many ways to utilize biomass energy, among which direct combustion is the most common and extensive way to utilize biomass energy, which converts the solar energy stored in biomass into heat energy. [0003] In order to improve the utilization efficiency of biomass combustion, a technology of vibrating grate + high temperature and high pressure steam boiler is applied to biomass combustion for power generation or heat supply. The vibrating grate is composed of vibration mechanism, air chambe...
