Aug 26, 2009 · The developed dynamic model was used to build up a drum boiler simulator for the typical Romanian steam boilers from a power plant being in use in the Iasi area. The model has been validated in open loop system, using data from tests carried out on the actual plant. Open-loop studies include comparisons between simulation results and real plant

These equations are used to model all the units that comprise the boiler, adjusting them to each specific case. The most complex units from the point of view of modelling are the combustion furnace and the steam drum and, for this reason, it was considered necessary to describe them in more detail. 4.1 COMBUSTION FURNACE

A major condensate management project costing £70 000 expects to recover an additional 35% of the condensate produced at a plant. The average boiler steaming rate is 15000 kg/h, and the plant operates for 8000 h/year. The fuel used is gas on a firm tariff of £0.011/ kWh, and the boiler efficiency is estimated as 80%.

In this drum-boiler model, the control problem is to regulate boiler pressure in the face of random heat fluctuations from the furnace by adjusting the feed water flow rate and the nominal heat applied. For this example, 95% of the random heat fluctuations are less than 50% of the nominal heating value, which is not unusual for a furnace-fired
