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 ...

This work proposes an innovative method for adjusting the natural gas from grid to consumer pipeline requirements in a full-scale pressure reduction station. The use of two counterflow vortex tubes instead traditional boiler preheat before throttling is demonstrated as powerful alternative. Thus, fossil fuel consumption reached, which amounts 7.1% less CO2 emitted. To ensure optimal configurati...
