1. This is related to the temperature and waste heat flow rate, and of course it is also related to the narrow point, end difference and closing point temperature difference of the boiler design;
2. The settings must ensure superheated steam to avoid damage to the turbine blades. Water impact;
3. Waste heat should provide continuity, proper flow and the best temperature is 500°C.
What is a waste thermal energy production project?
In short, it uses the combustion gases emitted by energy-intensive companies and recovers available waste heat to produce electricity.
Energy-intensive enterprises refer to some large energy consumers in the steel, chemical, building materials and other industries.
These generally use dvarious industrial furnaces that consume a lot of fuel, such as blast furnaces, converters and sintering furnaces in steel mills, coke ovens in coking plants, various furnaces in non-ferrous metal manufacturers and rotary kilns in cement factories, pool furnace in glass factory, tunnel kiln in ceramic factory, sulfuric acid reactor in chemical factory and pesticide factory, etc.
All types of high temperature industrial ovens emit combustion gases. According to the flue gas temperature, they are divided into high temperature, medium temperature and low temperature. The higher the temperature, the higher the quality of the energy, the more energy it is possible to recover and the greater the electricity production.
The process of producing waste thermal energy consists of the flue gases exchanging heat through the heat boilerr residual, and the boiler produces steam, which is fed into the steam turbine to drive the generator.
The core technology of waste thermal energy production is high-efficiency heat exchangers and high-efficiency steam turbines.
The construction process of waste thermal energy production: design plan, equipment purchase, civil engineering, installation, commissioning and operation.
The construction contents include: boiler installation, turbine-generator unit installation, civil construction of the main factory building and circulation pool, electrical system and its connection.
Three main hosts: waste heat boiler, steam turbine and generator.
The production of pure thermal energy at low temperatures means that no fuel is added, but only the energy of the combustion gasesat low temperature is used.
The number of people in a waste heat plant: usually 14 or more.
The installed capacity of waste heat power plants: typically 3 MW to 20 MW.
The construction period of the waste heat plant: 9 months to 18 months.
The investment scale of waste heat power plants: tens to hundreds of millions.
Does the wastewater treatment plant have waste thermal energy production equipment?
The waste thermal energy production project refers to the use of sensible or latent heat from waste gases, wastewater, waste. residues and other media generated in industrial production, through relevant equipment, an engineering project that converts thermal energy into electrical energy. For example, thermal energy from waste can bebe used to heat water to generate steam to drive a turbine-generator unit to produce electricity, such as: cement kiln waste thermal power generation project, cement kiln waste thermal power generation project residual thermal energy from steel sintering cooler and waste; is burned to generate steam to drive a steam turbine or use gas-steam combined cycle method to generate electricity, such as steel blast furnace gas power generation, thermal power generation residual coalbed methane, etc.
Yes, waste thermal energy generation is a technology that converts excess thermal energy into electrical energy during the production process. The production of waste thermal energy not only saves energy, but also benefits environmental protection. Important equipment for productionn of residual thermal energy is the waste heat boiler. It uses waste gases, waste liquids and other working fluids. Heat or combustible materials are used as a heat source to produce steam for power generation. Since the temperature of the working fluid is not high, the boiler is large and consumes a lot of metal. Waste heat used for power generation mainly includes: waste heat of high temperature combustion gases, waste heat of chemical reactions, waste heat of waste gases and waste liquids, low temperature waste heat (lower at 200°C), etc. Additionally, there are also ways to use the excess pressure difference to generate electricity; for example, blast furnace gas has high pressure at the top of the furnace, which can be used to produce electricityity via an expansion turbine generator before being sent. to gas users
