Product Description

Product Description

Energy Conversion Process

• High-temperature and high-pressure steam enters the turbine through the steam inlet, pushing the blades to drive the rotor to rotate, converting the thermal energy of the steam into mechanical energy (to drive a generator for power generation or directly drive machinery).
• After expanding and doing work in the turbine, the steam is discharged at a pressure higher than atmospheric pressure (i.e., "backpressure"), rather than being discharged into a condenser for cooling like a condensing steam turbine.
• The exhaust steam can be directly supplied to heat users (such as factory heating, process steam, etc.), achieving combined heat and power (CHP) and improving energy utilization efficiency.

Regulation Modes

• Power-determined heat supply: The power generation is controlled by adjusting the steam inlet volume, and the exhaust steam volume changes with the power generation.
• Heat-determined power generation: The steam inlet volume is adjusted according to the heat load demand, and the power generation changes with the heat load.

Chemical Industry:
Provides high-temperature steam for processes such as distillation, reaction, and polymerization in chemical production, such as crude oil distillation in petroleum refining and synthetic ammonia process in fertilizer production.
 Utilizes high backpressure turbines to drive large machinery such as chemical pumps and compressors, achieving integration of power supply and thermal energy supply.

Metallurgical Industry:
In steel mills, high-backpressure turbines can utilize by-products such as blast furnace gas and coke oven gas to generate electricity, while also providing steam for the heating furnaces and heat treatment equipment in the rolling workshop, supporting the steel rolling and heat treatment processes.

Paper Industry:
Provides steam for the pulping, papermaking, and drying stages of the paper-making process, such as the high-temperature heat source required for drying paper, while also driving the operation of papermaking machinery to improve production efficiency.

Food and Textile Industry:
In food processing, steam is used for sterilization, cooking, and drying (such as canning and grain drying), while in the textile industry, it is used for heating and setting processes in dyeing and spinning. A stable supply of steam is crucial to product quality.
