Container type biomass pressurized combustion power generation system capable of being applied to island

Abstract

The invention discloses a container type biomass pressurized combustion power generation system capable of being applied to an island, and relates to the field of biomass combustion power generation. According to the route, biomass is pressurized and combusted to generate high-temperature flue gas, heat in the high-temperature flue gas is transferred to air through heat exchange, and the air drives a turbine to drive a power generator to generate power. And a movable power generation system with the generated electric energy capable of being stored in real time is included. Equipment in the system is installed in the same container, a gas compressor, the turbine and the power generator are coaxially arranged, and the pressure in a pressurized combustion furnace is cooperatively adjusted through the gas compressor and the turbine. The biomass is combusted in the pressurized combustion furnace, the generated high-temperature flue gas and the air are subjected to indirect heat exchange in a flue gas / air heat exchanger, and the heated air drives the turbine and drives the power generator to generate electric energy, and the produced electric energy is merged into an island power grid. The pressurized air discharged by the turbine exchanges heat with ash and then enters the pressurized combustion furnace to serve as an oxidizing medium for biomass combustion. The system is small in occupied area and can be placed on carrying equipment.

Description

technical field [0001] The invention relates to the technical field of biomass combustion power generation, and more specifically, constructs a new container-type system that can be applied to biomass pressurized combustion power generation and heat production in island areas. Background technique [0002] Islands have unique geographical properties and are surrounded by the sea on all sides. They are generally far away from the mainland. Except for some islands that are relatively close to the mainland and can be connected to the mainland power grid through submarine cables, most of the islands are mostly isolated due to economical and technical implementation difficulties. The residents on the island rely mainly on diesel power generation, and the energy structure is single. The high price of diesel oil and the need for long-distance transportation lead to high power generation costs on the island. The explosive and flammable chemical properties of diesel oil make large-sc...

AI Technical Summary

Problems solved by technology

From the perspective of geographical environment, the area of ​​the island itself is limited, and the ecological environment on the island is fragile. If the biomass power station is large in scale and consumes too much biomass, it will easily cause damage to the ecological environment of the island.

From an economic point of view, isolated grid islands are far away from the mainland, and the materials required for the construction of large-scale biomass power stations are transported far away, resulting in high investment costs.
