2.2.1 Description of principal components
The boiler is made of the following components:
Fan [9]
The fan pulls in and compresses the combustion air, drawn from inside the casing of the boiler.
The fan is a DC current fan equipped with a speed feed-back signal. This speed feed-back signal
is transmitted back to the controller, which makes the necessary corrections.
Gas train
The main component of the gas train is the gas valve [17]. The gas quantity is controlled according
to the quantity of air. The air quantity varies with the speed of the fan. The gas train is equipped
with a test point through which the gas pipe can be vented or the gas inlet pressure can be meas-
ured.
