Answer: inches of water

Draft in a bolier is measured in ________ How can the answer be improved? If the breech draft is too low the combustion process and venting process may be inadequate and if the draft measured in the breech is lower than the draft measured over the fire the oil burner and combustion chamber are operating under pressure - which is often a problem on residential heating systems since few of them are designed to work … This draft pressure can be positive or negative depending of the boiler design; Natural draft Balance draft and Forced draft boilers are the most commonly used in the industry. Monitoring draft is important not only to increase combustion efficiency but also to maintain SAFE conditions. Draft Systems - Exam 10. STUDY. PLAY. draft is measured in ___ inches of water column ___ draft is created by a draft fan that pulls the gases of combustion through the furnace. induced. ... the gases of combustion leaving a boiler that has a natural draft are controlled by ___ dampers. Draft in the boiler is measured between two points such as the __and __. Pressure at the discharge side of a forced draft fan is __ atmospheric pressure To reduce the heat loss of flue gases going to the chimney boilers are equipped with __. Where multiple boilers are vented into the same chimney attempts should be made to balance the draft of each individual boiler with separate draft controls as opposed to one draft control in the main breaching. For example in the following diagram draft controls should be installed in location A or B. On many boilers air flow is the measured differential between the furnace inlet and the boiler outlet. This takes the differential of the hot gases as they flow through the furnace across the convection section and out the stack. In most cases the differential ranges from 0.5 to 2.0 inches of water. Draft volume specifies the cubic feet of gas that a chimney can handle in a given time. Draft intensity is measured in “inches of water”. Just as a mercury barometer is used to measure atmospheric pressure in inches of mercury a draft gauge is used to measure draft intensity (pressure) in inches of water. Natural Draft is thermal draft. It occurs … Thermal Power Plants: What is a negative DRAFT ? Update Cancel. ad by Zoho. Automate your business with Zoho One.
