Tear holes on the water seal tank body of the catalytic residual boiler
Thread Content
What is the structure of the weep hole on the water seal tank body? What is its function? When to use it?
The tear holes on the water seal tank were proposed by the equipment specialists to prevent overpressure and to balance the pressures inside and outside the tank. However, in practice the pressures inside and outside the tube are not equal; therefore, those holes were promptly sealed! Improve the liquid seal effect!
During startup, the lining inside is not dry; without these holes for thermal expansion, the gas trapped inside cannot escape, which can easily lead to damage to the equipment. They are useless during normal operation
What structure? Why doesn’t it leak air during normal operation?
Is it for allowing air to pass through despite the lining? When the remaining pot is removed and water is added, water comes out from some drainage holes; is its structure just a hole with an inner lining?
