Dynamic simulation of fouling in a circulating fluidized biomass-fired boiler

Understanding mineral behaviors during anthracite fluidized-bed gasification based on slag characteristics

“…The main cause of slag formation during gasification or combustion is the large amount of minerals of alkaline-earth and alkali metals that are produced [23][24][25]. Recently, some indexes for predicting slagging tendency during coal gasification have been proposed on the basis of ash characteristics [26][27][28][29].…”

Modelling and Simulating Energy Conversion Processes using Modelica

“…The model is validated towards real plant data and is capable of successfully predict operation performance. An exhaustive description of this model can be found in Sandberg et al (2011).…”

Prediction of Pollution State of Heating Surface in Coal-Fired Utility Boilers

“…If the soot blowing operation is not carried out in time, it will cause too much ash deposition on the heating surface, reduce the heat transfer efficiency, and even cause accidents, which will affect the safety and economy of boiler production; if the soot blowing frequency is too high, it will not only cause excessive waste of soot blowing steam, but also cause erosion of heating surface and affect the service life of equipment. Therefore, under the limited conditions of soot blowing cost, production efficiency, and production constraints, it is of great significance to determine the most efficient soot blowing operation mode for the safety of the whole unit, energy saving and emission reduction [6][7][8][9] .…”
