startup curves computed on-line are then inte-grated into the existing unit control concept, serving as correction setpoints. The prediction horizon is 60 to 90 minutes, thus covering the entire length of a boiler startup up to the point where the turbine is rolled on

Read Moreboiler, the mid-fire range is the most effi-cient operation. Myth No. 2: Radiation losses are so minor they can be ignored. As with the full-load assumption, it's also a myth that one can ignore "minor" radiation losses. The radiation losses seen in figure 2 are estimated
Read MoreA gas/oil boiler has no inventory or bed of fuel. When you trip the burner, for all practical purposes, the heat input immediately stops. With solid fuel units, however, a fairly large mass of bark, coal, etc., is still on the grate and even though starved of air by the loss of the forced draft fan, these units have more "thermal inertia" and will continue to produce some heat.
