Good day, We setting up a piloting facility with a 30-ton-per-day vertical shaft kiln and requires assistance in selecting suitable stack emission monitoring equipment to comply with environmental regulations. Could you please provide us with a range of options to choose from, as well as the cost of each option?  Stack height is 5m, stack diameter is 0.3, and stack orientation is vertical. The kiln has a height of 19 m and an external shaft diameter of 3.2 m. Please include as well portable machines. Coal is used as a fuel source and we would like to measure the combustion gases such as CO, CO2, SO2, NOx, O2, particulate matter, and water vapour. Kind regards, Nozonke
