Further, it is necessary to ensure the
exhaust gas temperature out of the heat exchanger higher than 200[degrees]C in order to avoid the dew point corrosive phenomenon.
Many LTHW boilers are limited to a turndown of just 2:1 or 3:1 to ensure that the boiler
exhaust gas temperatures are maintained above the 130-140[degrees]C required to avoid condensation.
This trend of exhaust heat loss can also be explained from the
exhaust gas temperature characteristics.
The
exhaust gas temperature and flow rate with increasing the engine load is increased.
Another problem can occur when an engine is shut down quickly after being operated at high speed and load where the
exhaust gas temperature is maximized.
