Abstract

This bachelor thesis deals with measuring the dew point on the boiler K1. The first part of the thesis describes the boiler K1, the description of the air heater, the temperature distribution in the space above the air heater and the description of the other parts of the boiler. The second part is focused on the dew point, a chemici reaction in the flue gas, the posibility of protection against low-temperature corrosion and description of the measuring probe Lancom 200. Practical part concerns metodology measuring dew point this probe, the measurement time schedule and the measurement results. The third, computational part, deals with analysis of selected rating gases, calculation of combustion gases composition, combustion equations of individual gas components, total amount of necessary combustion air and resulting flue gas during selected measurement.
