Theme II. Peat for horticulture, energy and other uses
The chemical properties needed to characterise the critical properties of peat as fuel and the analytical methods to be used are given in the Nordtest Method, NT ENVIR 009 – Quality Guidelines for Fuel Peat (approved in November 2005) and in former Finnish guidelines 1989 and 1991.
A large quality data set of fuel analyses concerning years 2001 to 2011 was collected.
The samples of this quality data are taken mainly from deliveries in order to determine the properties needed for invoicing, verification of the agreed quality, and control of emissions:
net calorific value, ash content, CHNS and volatile matter. Samples taken for production control, for quality control and management of storage and for R&D purposes are also included. The main statistical figures as well as the distribution for all the determined properties are also given.
