Dynamics and Control of a Gas-fired Furnace
A non-linear model has been developed for a gas-fired furnace in which oil is heated. The model is applicable from minimum to maximum heat load of the furnace. The dynamics of the model have been compared to experimental results, which were obtained for a pilot-scale furnace. They are in good agreement. A cascade control with feed-forward action has been compared to single feed-back control. Pr...
متن کاملFurnace Wall Corrosion in a Wood-fired Boiler
The use of renewable wood-based fuel has been increasing in the last few decades because it is said to be carbon neutral. However, wood-based fuel, and especially used wood (also known as recycled wood or waste wood), is more corrosive than virgin wood (forest fuel), because of higher amounts of chlorine and heavy metals. These elements increase the corrosion problems at the furnace walls where...
متن کاملThe Modeling of a Laboratory Natural Gas - Fired Furnace with a Higher - OrderProjection Method for Unsteady Combustion
A higher-order, embedded boundary projection method for axisymmetric, unsteady, low-Mach number combustion is used to model a natural gas ame from a 300kW IFRF burner in the Burner Engineering Research Laboratory (BERL) at Sandia National Laboratory under hot wall conditions. The numerical predictions presented are the late simulated-time results of a computation of unsteady ow in the furnace. ...
متن کاملA mathematical model of a direct-fired continuous strip annealing furnace
Amathematical model of a direct-fired continuous strip annealing furnace is developed. The first-principle model uses the heat balance to describe the dynamic behavior of the strip and the rolls. Themass and the enthalpy balance are employed to calculate themass, the composition, and the temperature of the flue gas. The heat conduction equation of the furnace wall is discretized bymeans of the ...
متن کاملNumerical Simulation of NO Production in Air-Staged Pulverized Coal Fired Furnace
We describe behavior of the air-coal mixture using the Navier-Stokes equations for the mixture of air and coal particles, accompanied by a turbulence model. The undergoing chemical reactions are described by the Arrhenian kinetics (reaction rate proportional to RT E e ). We also consider the heat transfer via conduction and radiation. The system of PDEs is discretized using the finite volume me...
