The existing power facilities of the Republic Tatarstan face a number disadvantages related to system for recording data on technical condition boiler and turbine equipment: manual calculation parameters equipment operation, lack direct access complete information and, as result, low efficiency in identifying malfunctions, deviations operation equipment, carrying out repair work. Hence, need di...

Fossil fuel thermal power plants account for almost 60% of Russian electricity and heat. Steam turbine units make 80% this amount. The main method steam unit efficiency improvement is the increase in initial parameters’ temperature pressure. This reduces fossil consumption harmful emissions but requires application heat-resistant steel. steel’s heat resistance leads to a non-linear price increa...

This paper studies a planning problem for heating water. Hereby, boilers (e.g. gas or electric boilers, heat pumps or microCHPs) are used to heat the water and store it for domestic demands. We consider a simple boiler which is either turned on or turned off and has a buffer of limited capacity. The energy needed to run the boiler has to be bought on a day-ahead market, so we are interested in ...

In this paper a neuro-predictive method is proposed in order to control the water level in the steam drum boiler system being in use at a Power Plant of Iaşi, Romania. The steam boiler provides thermal and electrical power and it works under complex technology in order to satisfy numerous technical, security and economical requirements. A nonlinear dynamic simulator for the proposed steam drum ...

Sustainability and efficient use of resources are becoming increasingly important aspects in the operation all industries. Recently, some biomass-fired boilers have been equipped with complex condensing back-end heat recovery solutions, sometimes also using pumps to upgrade low-grade heat. In kraft boilers, however, scrubbers still mainly for gas cleaning, only simple solutions. this paper, we ...

According to the characteristics of boiler combustion process, we use image processing technique to extract features that characterize the features of flame. On requirements of good real-time performance boiler burning diagnose system, we develop a set of PC add DSP real-time image acquisition and burning diagnosis system on the 200MW boilers. The results show that the system is simple, practic...

An adaptive predictive control methodology is applied for a fossil fuel boiler control. The control algorithm takes advantage of a neuro-fuzzy identifier system for prediction of the boiler response in a future time window. An optimizer algorithm based on evolutionary programming technique (EP) uses the identifier-predicted outputs and determines input sequence in a time window. The present opt...
