For many years, the Department of Power Engineering and Turbomachinery Silesian University Technology has been using a small-capacity (about 500 kW e ) steam-gas power plant. Based on years experience in operation this plant utilizing Velox-type gas-steam system, an idea arose to modify type thermal cycle create combined heat (CHP) small capacity, dedicated for distributed production or process...

Ash fouling has been an important factor in reducing the heat transfer efficiency and safety of coal-fired power plant boilers. Scientific accurate prediction ash surfaces is basis formulating a reasonable soot blowing strategy to improve energy efficiency. This study presented comprehensive approach dynamic At first, cleanliness used reflect level surfaces. Then, model proposed predict deposit...

The coal fired thermal power plants plays major role in the power production in the world as they are available in abundance. Many of the existing power plants are based on the subcritical technology which can produce power with the efficiency of around 33%. But the newer plants are built on either supercritical or ultra-supercritical technology whose efficiency can be up to 50%. Main objective...

in this paper, first a sensitivity analysis of parameters affecting the performance of the steam generator is performed. this process includes the pinch temperature difference and the gas velocity (width of the hrsg) as the operating parameter and geometrical parameters (fin’s thickness, fin’s height, number of fins in each inch, tube transverse pitch) for each pressure parts is carried out, an...

Three model configurations are presented for multi-step time series predictions of the heat absorbed by water and steam in a thermal power plant. The models predict over horizons 2, 4, 6 steps into future, where each step is 5-minute increment. evaluated pure machine learning model, novel hybrid physics-based with an incomplete dataset. deconstructs individual boiler absorption units: economize...

As it is known that the boiler a device used to heat water. This research conducted propose another alternative in energy saving efforts by utilizing exhaust gas from Diesel motors which so far have not received much attention. The gases reused react boiler. method design this tool uses literature study method. data taken of 9 x 12 4 cylinders engine with speed 300 rpm and Mep 80 Psi, power (N)...
