The Sankey Diagram in Energy and Material Flow Management

Mar 19, 2008 · The top chart in figure 1 shows an American steam engine (Louisville Leavitt Pumping Engine). The steam leaves the boiler with a quantity of 159,250 B.T.U./min (B.T.U. = British thermal unit, an old energy unit: 1 B.T.U. = 1.055 kiloJoules [kJ]). If the refluxes are taken into account, the net supply to the steam engine is 142,150 B.T.U.

US4655392A - Steam-generator control method - Google Patents

A steam-generator control method is proposed for controlling the mass flowsf an oxidant and a fuel which are supplied for combustion. In order to control the flows at stoichiometric ratios with a required accuracy, the controlled variables are established by the measurements of the mass flows and their comparison with theoretically predetermined stoichiometric ratios.

Taking Stock of Engineering Epistemology

Sep 26, 2018 · As steam engineering expanded along with boiler explosions, a new regulatory law was passed in August 1852, which came into effect from 1 January 1853, requiring examination and licensing of engineers of the passenger steamboats (Rice 2004; also, Hunter 1985, Ch. 6 for boiler explosions). This law also sets the standards for competency
