Find and download the latest technical papers and presentations of industry experts who share their know-how on current trends and projects.   This month's special is our technical paper “Water-free combined cycle distributed power generation”. The clear benefit of a water-free combined cycle power plant solution is the ability to offer ‘zero water’ flexible distributed power generation with combined cycle efficiencies in regions where water is unavailable or a scarce resource, without incurring large additional costs or seeing significant reductions in power plant performance. Implementing the Organic Rankine Cycle (ORC) offers a competitive alternative to conventional ‘steam’ combined cycle concepts.   It was recently presented at POWER-GEN Asia 2018 and won the Best Paper Award within the category ‘Power Plant Technologies’. We are proud to share it with you.

Presented at Sugar Industry 2017

Cane sugar is manufactured in sugar mills in tropical and semi-tropical regions. For every 10 t of sugarcane crushed, a sugar factory produces nearly 3 t of bagasse as a byproduct. The bagasse contains enough energy to allow the mill to be self-sufficient with respect to steam and power requirements. Depending on the mill’s efficiency, location, and the local electricity grid, excess power may also be fed into the grid for additional revenue. 

In a typical cane sugar mill, approximately 500 kg of low-pressure process steam are required to process 1 t of cane. Along with generating steam for the process, steam turbines are also used to drive the cane milling tandems. Condensing or backpressure turbines in a single or multistage design can be used in the sugar-making process. Optionally, the turbines can also be equipped with single extraction options or multiple controlled (pass-out) and uncontrolled (bleeding) extraction options. Single-stage back-pressure impulse-type turbines have about 25% to 30% efficiency. A condensing steam turbine (multi-stage steam turbines) can operate at efficiencies from 80% to 89%.

The condensation path maximizes electrical power output. The low-pressure steam required for the sugar/ethanol manufacturing process can be extracted from the appropriate stage of a condensing turbine. If the factory has excess steam due to appropriate energy-saving equipment, the energy contained in the steam can be recovered as electricity using a condensing turbine.

Since operational safety and reliability are major important requirements in the power generation business and its production systems are highly complex, digitalization has already been introduced since computers were available. However continuous progress is being made and increasing use of data during manufacturing and operation increase customer value.

This paper describes digital applications along the end2end value chain of power plants with a special focus on steam turbines and steam power plants. Big data based probabilistic methods are used during the design of components. Industry 4.0 focused on manufacturing processes adds major benefit to product quality (e.g. by closed-loop chain of computer aided design and manufacturing). Artificial intelligence of control systems considerably improves operational performance by connection of power plant components and self-learning optimization algorithms. Finally big data analysis of operating records in combination with the digital twin of the plant enables condition based maintenance and adds value for customers to optimize inspections.
