Power generation in fiber industry

The Yankee drying process is the most common drying method. Small gas turbines are desirable for use in the Yankee process because the demand for hot air is lower compared with the Through Air Dryer (TAD) process. TAD uses heat to dewater the product instead of the conventional mechanical pressing. This produces a much softer paper and reduces the demand for raw material from 8% to 30%, but dramatically increases the drying load. The high demand of hot air means that the implementation of gas turbines up to 10 MW is profitable for the TAD process.

As part of China's efforts to reduce coal consumption nationwide, it became crucial for the Shanghai Orient Champion Paper to respond to the government's coal-to-gas policy. Following Shanghai Orient Champion Paper's mission, the management decided to invest in its own clean power generation and began to explore the option of clean and efficient gas-fired combined on-site heat and power generation.

The Stora Enso Beihai mill has an annual capacity of 450,000 tons of liquid packaging board and other high-grade paperboard products.

Two Siemens SST-800 steam turbines are supplying electricity and process steam to a pulp factory in Brazil. With a power output capacity of 190 MW the turbines are among the largest steam turbines in use in the pulp and paper industry worldwide.
Extra electricity provided for the nation grid.
Scope of supply: SST-800 backpressure steam turbine and SST-800 condensing steam turbine | power output: 190 MW (each) | speed: 3600 rpm, inlet steam pressure: 100 bar | inlet steam temperature: 498°C | extraction pressure: 10 bar

Metsä Group’s Äänekoski bioproduct mill is utilizing raw wood material and production side streams to manufacture a wide range of bioproducts.
Bioproduct mill produces 2.4 times as much electricity as it needs, with the excess electricity being fed into the grid.
SST-800/500 steam turbine, automation solutions and digital analysis of production data triple capacity of the new mill.

APP is one of the leading paper and pulp companies and one of Asia’s biggest paper and pulp producers. The annual capacity of the plant is almost 1.5 million tonnes of pulp.
Optimized production costs make customers less vulnerable to the usual fluctuations in the market price of the end product.
Reduced energy consumption and CO₂ emissions.
Steam turbine: 2x SST-800 | power output: 120 MW (each) | inlet steam temperature: 475 °C | inlet steam pressure: 80.5 bar | speed: 3000 rpm | extraction steam pressure: 6.5 bar
