In order to dissipate heat and prevent the casing from overheating, the casing is usually made of ordinary carbon steel.
Burners and sulfur furnaces usually do not need to be insulated, otherwise they are prone to overheating. However, it is necessary to add a rainproof and anti-scalding cover, and have exhaust outlets on the upper and lower parts.
The lowest temperature where our equipment is located is minus 20 or 30 degrees Celsius. Is it okay without insulation?
In several factories in Xinjiang, the burners do not have rainproof covers.
What is this consideration based on? Today a Krause manufacturer came over and said that without a rain cover it will easily corrode.
Is it the furnace or the burner that the manufacturer says will corrode without a rain cover?
I didn’t mention this, I just said that it is prone to acid dew point corrosion. It should corrode the furnace. The burner is exposed to the outside.
Usually there are requirements for the outer wall temperature of a sulfur furnace or incinerator, so recently designed documents generally add thermocouples to the furnace wall to monitor its temperature. The temperature cannot be too low, otherwise dew point corrosion will easily occur. If there is no rain cover, the temperature of the furnace wall will drop sharply once it rains, eventually leading to dew point corrosion.
So, the poster you are asking is whether the burner should be equipped with a rain cover?* * Already? There are burners with or without additional burners, but the furnaces all have rainproof covers.
Another reason is that damage to the internal refractory coating can be detected early
