vacuum-water-boiler-t6

vacuum water boiler t6

The boiler adopts an environmentally friendly combustion method - full premixed combustion, and the gas and air are precisely adjusted and premixed in advance to ensure more complete combustion.

water-tube-steam-boiler

water tube steam boiler

The boiler adopts a double-drum longitudinal "D" type arrangement structure; water, steam or steam-water mixture flows in the pipe; flame burns and flue gas flows outside the pipe, forming extremely fast steam-water.

CiteSeerX — Simulation of a Steam-boiler

The simulation imitates the behaviour of the steam-boiler and can be controlled using a simple ASCII protocol. It reacts to defined commands and sends information about its state every five seconds. Furthermore, we describe the options available, the protocol which functions as an interface between the simulation and the controller, and how one can simulate component failures within the boiler.
