Resource or Project Abstract

This data set contains a summary of tests performed on a 20kW wood pellet boiler performed primarily to measure NOx and PM emission factors, but also to examine the boiler performance and efficiency at all operating modes. A total of 21 tests were performed on this boiler and details of each individual test are also included in the dataset. Six different operating modes were examined. Power Level 5 (PL5) represented operation at the nominal boiler output and was the design condition with corresponding low emission levels. PL4-PL1 were operating modes at reduced output, the aim of which is to modulate heat output to match demand in a boiler installed in a house. Combustion conditions moved away from optimum settings and PM rose accordingly. The startup phase lasted approx 10-15 minutes and this is the subject of a separate test series. Finally a summary of all of the relevant parameters is included in a separate spreadsheet.

Within each of these individual results files there are 7 broad segments. The first part contains details of the PM mass measurements that were carried out; recorded mass increased of the PM substrates, experiment notes, atmospheric conditions, etc. Part 2 gives details of the fuel consumption data for each test while Part 3 contains the results from the LabVIEW Data Acquisition System that was used to record all operating parameters used to measure boiler performance, e.g. water flow and return temperatures, water flow rate, flue temperature, ambient temperature, boiler heat output, etc. Part 4 contains results from the Testo 350 M/XL gas analyser which was used to measure NOx concentration as well as O2, CO, CO2 and H2. In addition this part also includes details of all calculations performed on this data to calculate the various emission factors in a variety of units. In part 5 the PM data captured by the low pressure impactor is inverted to find the PM mass size distribution and emission factor in a variety of units. An uncertainty analysis of all measurements, and a calculation to determine how each individual error propagates through the measurement train to yield an overall uncertainty is included in Part 6. Finally a summary of the relevant parameters is given in Part 7.

Description of Geographical Characteristics of This Project or Dataset
Laboratory based. Particulate matter measured using a Dekati Low Pressure Impactor (DLPI). NOx and other gaseous emissions measured using a Testo 350 M/XL gas analyser. Boiler performance recorded using a National Instruments Data Acquisition System (DAQ). A typical domestic duty cycle (details in dataset 4) was imposed on the boiler in the laboratory where controlled experiments coould be carried out to measure emissions concentration. Steady state operation as well as start-up and transient operation was examined.
