The method presented in this paper gives not only the availability loss in each elementary step of the whole process in the engine, but also an insight into how big is the part of burnt fuel available during an elementary piston motion, something which cannot even theoretically be realised as pΔV work. This method is based on decomposition of a complex real process to so-called elementary processes equivalent to the real one. Practical applications of the decomposition method favour antecedence plotting of special u-s diagrams for combustion products.

Optimizing VOC Combustion - Case Study
Volatile Organic Compounds (VOCs) are pre-cursors to Ozone pollution and subject to EPA regulations. Thermal and catalytic oxidizers are routinely used to destroy VOC emissions from a variety of industrial sources. NOx and CO are common byproducts created in the burning of natural gas. All of these pollutants can be effectively minimized, but the challenge is engineering a solution that has to work within constraints of an existing system while remaining cost effective to operate. We wanted to share the...
Combustible Dust: It Doesn’t Take Much
A dust accumulation of 1/32 of an inch deep—about the thickness of a dime—covering just five percent of a room’s surface area doesn’t sound like much, but it’s enough to cause a catastrophic explosion, according to the National Fire Protection Association (NFPA). Although good engineering and safety practices to prevent dust explosions have existed for decades, there are no government standards for general industry requiring and enforcing policies aimed at preventing combustible...
Why high temperature combustion of landfill gas?
Due to the accumulation of knowledge and the tightening of environmental law, the landfill technology has increasingly become concerned with the management of trace compounds in landfill gas.With landfill gas, contamination is through sulphur, chlorine, fluorine, halogenated hydrocarbons and heavy metals. Other trace elements such as volatile organic compounds (VOC), impose environmental loading factors.High temperature combustion is designed to safely and completely eliminate environmental risk.The "clean"...
The landfill gas collection, utilisation and surplus gas combustion acting in unison
In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, which orientates itself to the requirement of the energy consumer Between them, the flare fulfils the important task of burning off safely surplus gas quantities; and...
Aircraft Engine Remote Visual Inspection
An aircraft MRO center was in need of an easy to use borescope for use in a wide variety of applications on both turbine and piston powered aircraft. The VJ-Advance (VJ-ADV) from RF System Lab was selected because of its unique combination of features and very competitive price. Using the VJ-ADV, technicians are now able to conduct engine and airframe inspections quickly and easily, documenting with pictures and video the condition of any internal component or inspection target. The VJ-ADV has become a standard...
