Emissions measurement moisture content

For determination of the total mass-emission rate of SO9, the moisture content and the volumetric flow rate of the exhaust gas stream must also be measured. 

Based on a similar approach, a statistical analysis was conducted to determine whether correlations of CO and CH4 emissions could be established with a number of variables including fuel moisture content, fuel particle size distribution, fuel feed rate and excess air ratio. With the limited number of observations, the best model for CO was derived as a function of fuel moisture content (Fig, 1) for the combustor used for these studies. There was no evidence for correlation of the other variables. The measured CH4 contents also had an increasing trend with higher moisture contents of the fuels, but could not to be fitted in any correlation equation. 

Continuous Measurements In order to be as close as possible to practical conditions, measurements were conducted at 23 C. The nitrogen moisture content was suddenly increased during the test and the variations of the formaldehyde emission were observed at the same time. 

Insulation of the floor of broiler houses prevents moisture condensing on the concrete surface and thus has an effect on the dry matter content of the litter. This effect can be expected wherever the ground water level is about one metre below the surface. The theoretical principles are given Other benefits of the insulation are a reduction in ammonia and odour emission, as well as an improvement in the quality of the broilers as measured by the presence of blistered briskets and wrong legs. The economic implications, however, remain unclear.
