The CTFC laboratory protocols followed European cm101 regulations (EN) concerning the characterization of biofuels, ensuring the accuracy and repeatability of the samples and characterized biofuel according to UNE-EN 14961-1. Solid biofuels. Fuel specifications and classes.
The analyzes offered are listed below for each type of biofuel, considering: sliver, pellet, briquette, etc.. accordance with the regulations that are based on CEN and Önorm if any (grain) Grading cm101 (P)
To determine the size distribution of the particles for inclusion in the category concerned. It has been the carbon material in the series of sieves arranged in the light of the sieve. From a vibrating or oscillating movement speed and duration determined the percentage of material obtained by size. Used to qualify as a biofuel use if you want to give.
Moisture is the water content in biodiesel. Estimated the difference between cm101 wet weight of the material and the material drying oven to constant weight; understood cm101 to constant weight when the weight difference is less than 0.2%.
The calorific value is the amount of energy released per unit mass when burning biofuel. cm101 The sample obtained passes a size reduction process to obtain particles less than a millimeter. Compressed gram sample for analysis in the calorimeter, which records the combustion temperature rise in the sample. Get the calorific value (PCS) which obtained the inferior cm101 calorific power (PCI). PCS (qv, g): The calorific value is the amount of energy released when a unit mass is burned with oxygen, the water being produced in the burning liquid. PCI (qp, net): PCS differs from that water released during combustion is in the gaseous state, is the unit of measure that usually work, since the water out of the boiler always gaseous state. To get the value of the PCI will be necessary to determine the amount of carbon, hydrogen and nitrogen.
It is the determination cm101 of carbon, hydrogen and nitrogen, the basic components of biofuel used to quantify the CO 2 or NO x. Values are needed to calculate the inferior calorific power.
The analysis of volatile matter cm101 contained in what is called "Immediate analysis," which also includes the analysis of ash and moisture. The material is made up of volatile gases and vapors evaporate in pyrolysis and are responsible for the flame in the combustion process. Also called "analysis of fixed carbon," which is the residue analysis after discounting the weight loss due to moisture, when heated in biofuel standard conditions up to 900 + 10 C.
Ash is the inorganic residue that occurs when the biofuel cm101 is burned. Determined under specific conditions to ensure that all the organic part was burned. These conditions are an increase in temperature control up to 550 + 10 C.
Bulk density, and weight or volume ratio is an important factor when the supply of biofuel and to estimate space requirements for storage and transport.
The mechanical durability of pellets is a factor that determines its quality, and to verify the resistance of the pellet in disintegrate or break up into finer particles. For the analysis the sample is placed in a rotating durabilímetre performing movements and revolutions of a certain duration to assess the percentage of material that has disintegrated.
While calculating the DU also calculated the amount Up (F) that are in the sample before analysis, this value describes to transport in bulk or in bags before delivery to the end user.
CTFC provides sampling service cm101 of biofuel governed by European standards UNE EN 14778-1-2. When the personal care of the CTFC sampling, cm101 the resulting report stating that the analyzed sample is representative of the original batch.
If the client sends the sample, the CTFC responsible for the show by the time it reaches the facilities of CTFC. The report cm101 is based on the sample, being responsible for the customer to take a representative sample of the lot.
