Industrial fan(ID FD Fans) 1. Industrial Fan 2. Draft System The function of draft in a combustion system is to exhaust the products of combustion into the atmosphere. The draft can be classified into two types namely Natural and Mechanical Draft. Natural Draft It is the draft produced by a chimney alone.
Tjernlund In-Line Draft Inducers assure positive draft when restricted boilers and furnaces, poor chimneys or negative pressures in buildings prevent proper exhaust of combustion gases.The venturi action starts air moving up the stack instantly & keeps it moving smoothly. These units are quick and easy to install and completely automatic in operation.
7. Exercise caution anytime a fan is used to exhaust air from a boiler room. Negatively pressurized boiler rooms can cause poor combustion and products of combustion to spill out of the barometric damper into the boiler room. Be sure the air pressure in the boiler room is the same as it is outdoors under all operating conditions. 8.

Exhaust Draft Control Introduction. Boilers must maintain a proper flue draft for efficient combustion; too little draft can result in condensation, CO formation, flue gas spillage, and soot formation. Too much draft results in lost thermal energy from the boiler and higher electrical usage by the vent fan.

Putting in an induced draft system eliminates that problem, too. Induced draft fans are common in mid-efficiency furnaces. We spoke earlier of needing 15 cubic feet of combustion air and 15 cubic feet of dilution air to burn one cubic foot of natural gas. With an induced draft fan, we only need the 15 cubic feet of combustion air, more or less.

A water tube boiler is such kind of boiler where the water is heated inside tubes and the hot gasses surround them. This is the basic definition of water tube boiler. Actually this boiler is just opposite of fire tube boiler where hot gasses are passed through tubes which are surrounded by water.. Advantages of Water Tube Boiler. There are many advantages of water tube boiler due to which
The difference between atmospheric pressure and the pressure existing in the furnace or flue gas passage of a boiler is termed as draft. Draft can also be referred to as the difference in pressure in the combustion chamber area which results in the motion of the flue gases and the air flow.

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7-2,000 kPa or 1-290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

NOTE: Triad highly recommends that boiler feed water be treated before it enters the boiler. The water in the boiler should have a pH level of between 7.5 and 8.5, and in no case above 9.5. If feed water temperature is below 140°F it also requires an oxygen scavenger. See WATER in Section III of this boiler manual.
