Basic Water Treatment of Steam Boilers

In order to fully understand what a given boiler needs for treatment, a basic study of its supply water must be done first. Three types of impurities exist in all supplies and can cause a wide range of problems in boilers and kilns. These impurities are suspended solids, dissolved solids, and dissolved gasses. Water picks up the impurities from the ground it contacts and the air through which i...

Economical optimization of steam data for recovery boilers

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...

Calculating the Efficiency of Steam Boilers Based on Its Most Effecting Factors: A Case Study

This paper is concerned with calculating boiler efficiency as one of the most important types of performance measurements in any steam power plant. That has a key role in determining the overall effectiveness of the whole system within the power station. For this calculation, a Visual-Basic program was developed, and a steam power plant known as El-Khmus power plant, Libya was selected as a cas...

Supplementary Document for Paper 1227

This is a social force (SF) based model that treats the crowd as a collection of mass particles [1]. Newtonian-like physics is applied to the system to compute the trajectories of the agents. At each time step, the superposition of various forces are computed for each agent, ultimately determining a feasible velocity by imparting acceleration on the agent. The preferred velocity is converted in...
