A slice of pizza contains 28 g of carbohydrate, 13 g of protein and fat. If the pizza contains 280 kcal, how many grams of fat are present? The caloric values are: 4 kcal/g for carbohydrate, 9 kcal/g for fat, and 4 kcal/g for protein. Round off the energy values for each food group to the tens place. A 28 g B 13 g C 10 g D 55 g E 250 g
The dust emitted from coal grinding contains a certain amount of coal powders. Coal bearing dust is flammable and explosive, and piles of coal powder will spontaneously ignite under certain conditions. Therefore, the dust collection equipment of the coal grinding system must have flame proof and explosion proof devices, such as an explosion
First stage – regrinding the coal of 10–15 mm fraction to pulverized coal of 0–30 μm fraction. First, we ground dry the coal of 10–15 mm fraction using AVS 150 vortex layer device for two minutes. Coal grinding was checked by means of testing sieves. 96% of coal passed through a 316 µm sieve. Next, the sifted sample was run
Coal may contain trace amounts of gases such as methane. When coal is handled, it can release some of these gases. Methane concentrations in coal unloading systems, Opening
Coal grinding to obtain watercoal fuel GlobeCore Oil . The diagram does not show a coarse coal grinding mill which makes it possible to obtain 613 mm particles As the figure shows, the
Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300 C. Inert kiln exhaust gases with oxygen content
