The subject can be broadly classified under two headings: Water Treatment and Combustion. It is not the object of this paper to elaborate the methods of running efficiency tests and their attendant calculations, but rather to discuss the laboratory and factory work of the chemist in this more or less engineering subject. I think we can safely say that the day is past when accidents and expensiv...

Based on an example of a gas-fired boiler for industrial user in Tianjin, the absorption heat pump technology was used to carry out energy-saving transformation above boiler. The actual test carried gas flow, exhaust temperature and other parameters from January 2, 2018 February 26, 2018. And then, thermal efficiency analysed. results show that after transformation, can be reduced 140 °C about ...

SPIN is a tool for the simulation and veriication of protocols. PROMELA, its source language, is a formal description technique like SDL and Estelle that is based on communicating state machines. The tool and the language are in the public domain and therefore widely used. The "Steam-Boiler Control Speciication Problem" consists of an informal speciication of a steam boiler system in a nuclear ...
