Calorific value and calorific value: How it works
While the NCV only reflects the energy content of a fuel, the GCV indicates how much thermal energy can be obtained in total by the heating system. Condensing technology uses the energy of the combustion gases to generate additional heat. The higher the NCV and GCV, the better for energy efficiency. Conventional heating technology, on the other ...

Szénacél kések: mire kell figyelni és miért érdemes használni
A szénacél kés felületét számos dolog befolyásolhatja, beleértve a nedvességet, a savas ételeket és a koptató anyagokat. Annak érdekében, hogy kése jól nézzen ki, rendszeresen tisztítsa meg, és kerülje a karcoló anyagok használatát a pengén. Használhat hónolórudat is, hogy a pengét élesen és jó állapotban tartsa.

The GCV score, Vg V g, therefore depends on the units of the response and/or on the specific data used in the model. As such you cannot compare, in a meaningful way, the GCV scores for the two models you showed in your example. The absolute value of the GCV score is interpretable as an estimation of the lack of fit of the model. Thanks for …

Why Two Gas Valves (SRV GCV) in Frame 5 GT
Nov 16, 2017. #1. I just want to share and confirm an information that i have about using two gas valves (SRV and GCV) in the frame 5 GTs. The first valve SRV (speed regulating valve) regulates the infravalve pressure (between srv and gcv). This pressure depends on the hp speed.
