why negative pressure is maintained in furnace?

May 03, 2017 · Positive pressure :- When the pressure in combustion area of the boiler is more than atmospheric pressure, normally forced draft boilers, HRSG are positive pressure. Negative pressure :-When the pressure in combustion area of the boiler is less than atmospheric pressure. This is achieved in balanced draft boilers by using Forced draft fans to force air into boiler (pressuring it)and Induced draft fans to remove air from the boilers to create negative pressure.

• Low-pressure boilers are designed to withstand a maximum of 15 psig steam or a M.A.W.P. 160 psig water. The boilers can be classified according to the following criteria. According to flow of water and hot gases: 1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot

• Oxygen scavenger is to be fed to the water section of the tank using a stainless steel quill. • In that water temperature is important for the removal of oxygen. This tank needs to be as hot as possible. • The problem with this type of system in particular is that if the tank temperature is held above 190° F there is a potential for feed water pump cavitation.
