Mathematical Model For Wate Tube Boiler
Mathematical modelling of transient processes in convective heated surfaces of boilers …
2007/5/11 · The paper presents a one-dimensional mathematical model for simulating the transient processes which occur in convective heated surfaces of boilers, namely superheaters and economizers. The proposed model is based on solving equation describing the energy conservation and is simplified because the mass and momentum balance equations are omitted. The suggested method considers …

Water Tube Boiler - Definition, Components, Working Principle …
A water tube boiler can be defined as a Steam boiler in which the flow of water in the tubes, as well as hot gases, enclose the tubes. Not like fire tube boilers, this boiler attains high-pressures, as well as high-steam capabilities, can be achieved. This is because of condensed tangential pressure on tubes which is known as hoop stress.

Simulation of control of water level in boiler drum | Semantic Scholar
Water level in boiler drum is nonlinear, large time-varying, strong-coupling and multivariable. On the basis of establishing mathematical model of the regulation of boiler drum water level, fuzzy control theory is used for designing the control system for water level in the boiler drum, fuzzy control and PID control are respectively used for controlling water level in the drum. At the same
