Detailed Introduction
The waste heat power generation project of the submerged arc furnace is the process of recovering the high-temperature flue gas or heat lost from the furnace body generated during the production of the submerged arc furnace and converting it into electrical energy.
Sources of Waste Heat
High-temperature flue gas: The submerged arc furnace produces a large amount of high-temperature flue gas (usually between 400°C and 800°C) during production, which contains a significant amount of thermal energy.
Furnace body heat dissipation: The heat lost from the surface of the submerged arc furnace body can also be utilized through heat recovery technology.
Components of the Waste Heat Power Generation System
The submerged arc furnace waste heat power generation system typically includes the following main parts:
(1) Waste Heat Recovery Devices
Waste heat boiler: Uses the heat from high-temperature flue gas to generate steam and is the core equipment for waste heat power generation.
Heat pipe heat exchanger: In some cases, heat pipe technology is used to recover heat from the flue gas.
(2) Steam Power Generation System
Steam turbine: Converts the high-temperature, high-pressure steam produced by the waste heat boiler into mechanical energy.
Generator: Converts the mechanical energy from the steam turbine into electrical energy.
Condenser: Condenses the low-temperature, low-pressure steam discharged from the steam turbine into water for recycling.
(3) Flue Gas Treatment System
Dust removal equipment: Removes dust from the flue gas before it enters the waste heat boiler to prevent equipment wear and blockage.
Desulfurization and denitrification equipment: Treats the flue gas to remove sulfur and nitrogen oxides according to environmental protection requirements, reducing pollutant emissions.
(4) Circulating Water System
Cooling tower: Used to cool the circulating water in the condenser.
Water pump: Pumps the cooled water to the condenser , forming a circulation loop.
(5) Control System
Automated control system: Used to monitor and control the operating status of equipment such as the waste heat boiler, steam turbine, and generator.
Data acquisition system: Collects real-time parameters such as temperature, pressure, and flow to ensure safe and efficient system operation.
Workflow
(1) Flue gas recovery: High-temperature flue gas generated by the submerged arc furnace enters the waste heat boiler through the flue.
(2) Energy conversion: The waste heat boiler uses the heat from the flue gas to generate high-temperature, high-pressure steam.
(3) Power generation: The steam drives the steam turbine to rotate, which drives the generator to produce electricity.
(4) Condensation and circulation: The steam is cooled into water in the condenser and re-enters the waste heat boiler for recycling.
(5) Flue gas emission: The flue gas, after waste heat recovery and treatment, is discharged through the chimney meeting emission standards.
Technical Advantages
Energy saving and consumption reduction: Fully utilizes the waste heat resources of the submerged arc furnace to reduce energy consumption.
Pollution reduction: Reduces emissions of dust, sulfur dioxide, and nitrogen oxides through the flue gas treatment system.
Economic benefits: The generated electricity can meet part of the enterprise's power demand, reducing production costs.
Environmental benefits: Complies with national energy-saving and emission reduction policies, enhancing the company's social image.
