Unit No 4 consists of turbine-generator set and its auxiliary equipment. Turbine is supplied by steam extracted from other 3 turbines (No1, No2, No3). Calculated are: energy balance, efficiency, heat rate, efficiency deviation caused by steam, cooling water and ambient parameters.

Application is developed in form of Client-Server architecture. The new approach to the application structure allows broadcast whole set of displays within required frequency 10 s.

Coal dust fired boiler type OP140 with capacity 140 t/h operates in Saturn Power Plant as flexible source of steam consumed by Paper Machines.

Calculation of heat balance and boiler efficiency is based on Test Code DIN1942/94. Special dynamic compensation of input data has been applied for better computation during boiler transient conditions. Lab Module is used as interface between Chemical Laboratory and PHD Database.

Boiler No 5 (OP140)

CFB Boiler (manufactured by Foster Wheeler) fired hard coal.

Lab Module delivevers the results of technical analysis to application via PHD. Also carbon contents in fly ash and bottom ash are analysed.

Platform of application - MS Visual Studio. Client-Server architecture of application allows easy broadcast displays within Intranet. Displays content is renewed every 10 s.

In Client-Server architecture both part of the software plays complementary role. Server calculates all data to be displayed. Client retrieves data from server in form of XML document and next manages all necessary displays.

Boiler type OP140 is coal fired. Three fan type pulverizing mills supply dust to twelve tangential burners. Hot flue gas is used to dry coal dust in mills. Optimizer module calculates set points for boiler controllers to adjust actuators like: Air fans (2), secondary air dumpers (10), hot air to mills (3), dust separator in mills (3) and coal feeders (3).

Platform of application is Visual Basic 6.0. Calculated set-points in every 10 seconds are actualized in boiler controllers via PHD database. Displays are visualized in Operation Stations and are available for boiler operators.

CFB boiler coal and coal water slurry fired. Several boiler elements are chosen as limiting start-up procedure i.e. drum in upper side (steam), drum lower side (water), superheater headers (outlet Intrex) and refractory in combustion chamber and flue gas cyclones.

Start-up control is applied for boiler OP230 and turbine 13UP55. Thick elements being under control: for boiler drum, for turbine stop valve, outer housing, inner housing, flange.

Functions:

Boiler start-up allowed speed due to thermal stress, due to evaporation in economizer and recommended speed due to concurrency with turbine.

On line context help is embedded to the application assists to operator on his request and provide self-assistance according to start-up schedule Turbine start-up allowed speed due to thermal stresses in thick elements.

Start-up control is applied for turbine type V63. Thick elements being under control: turbine stop valve, housing, flange.

Turbine start-up allowed speed due to thermal stresses in thick elements.
