Energy saving is very important for economical and cost effective operation of the facility. In boilers, steam is produced for various process, utility and instrumental applications. It is very important to operate the boiler with proper operating conditions. The parameters like level of feed water, steam temperature and flow of steam need to be optimized. Various studies are carried out on opt...

This article explores whether ammonia is a reliable fuel for heat and electricity generation in domestic applications. First, the combustion characteristics, including adiabatic flame temperature, ignition delay time, laminar speed are analysed compared with conventional fuels such as natural gas, dimethyl ether, hydrogen, syngas, under 12 kWe turbine 45kWth boiler conditions. Furthermore, of a...

Pulp and paper mills are high power consuming industries. Pulp and integrated mills produce power via steam turbines in recovery boilers. Due to high power prices and the fact that biomass combusted in the recovery boiler is considered as green energy, there is today a desire to always increase the power generation when investing in new recovery boilers. In order to increase power output from t...

The facility is located four miles east of Hayden in Routt County, and consists of two BART-eligible boilers. Unit #1 is rated at 190 MW and is dry-bottom, wall-fired. Unit #2 is rated at 275 MW and is tangentially-fired. The Hayden boilers burn Colorado coal that primarily comes from two different mines in northwestern Colorado, the Twenty Mile Mine and the ColoWyo Mine. Coal characteristics a...

The system under study is an office building using two types of sources for heating: traditional gas boilers and energy-efficient, geothermal heat pumps. A Modelbased Predictive Control (MPC) strategy is suggested and tested in simulation, where the building is used as an active storage in order to decrease the morning peak loads and consequently the use of the boilers. The MPC algorithm aims a...

Technology for chemical cleaning of steam generators at fossil stations was developed during the latter half of the 20 century. Cleaning solvents and processes were developed for application to conventional boilers. The new fleet of combined cycle generating units with heat recovery steam generators (HRSGs) has raised questions concerning the applicability of technology developed for use in con...
