An evaporation ratio (steam to fuel ratio) of an efficient oil fired boiler is in the range of ___. a) 5 – 6 b) 13 - 16 c) 1 d) 7 – 9 7.VIEW DETAIL
In order to validate the calculation program, the predicted gas temperature exiting the boiler is compared with the operating data of the PFTA 500HP fire-tube boiler at different operating pressures and for three different types of fuel. This boiler operating data are found in Ref. 10. TheVIEW DETAIL
This system is used on most types of steam or hot water boilers, including fire-tube, industrial water-tube, and commercial water-tube. The control system is designed to operate a gas, oil, or combination burner using a single modulation motor and provides the best results when used with a fully modulating burner.VIEW DETAIL
Provide automatic boiler isolation valves to allow non-required boilers to be isolated from the primary boiler loop. This works only for boilers capable of withstanding thermal shock. Do not use this on cast iron, straight water tube, or fire tube boilers without using the previously mentioned thermal shock prevention techniques.VIEW DETAIL
(combo boiler) in which flue gas and water flow both outside and inside the tubes; the type contains an external furnace and shell-type boiler in a sequence. Fire tube boilers of smaller size are vertical and those of larger size are horizontal. The minimum capacity of a water tube boiler is usually around 5 tph.VIEW DETAIL

The customer said the old boiler heated the home "okay," so you decide to match the old boiler's size. Since the customer asked for an Alpine high efficiency condensing gas boiler, you review the product data sheet and discover that the closest Alpine models are 105,000 and 150,000 BTU/hr.VIEW DETAIL
Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots. Leading to local overheating. Scaling mechanism is the exceeding of theVIEW DETAIL
Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.VIEW DETAIL
2002-6-4 · EXAMPLE CALCULATION Fig. 1 is a waste-heat boiler operating under the following conditions: Gas flow = 200,000 lb/hr Gas inlet temperature = 1,650°F (vol% C02 =7, H2O = 18, N2 = 69, 02 = 6) Steam pressure = 500 psia Feed water temperature = 230°F The total steam generated is 63,5001b/hr. The first four rows are bare, followed by six finned tubesVIEW DETAIL
Use boiler horsepower to calculate steam flow. Boiler horsepower is not related to mechanical horsepower. It is a boiler industry rating that predicates the amount of saturated steam a boiler will generate starting with water at 212 degrees Fahrenheit and 0 pounds per square inch gauge (psig--meaning atmospheric pressure) and ending with steam at 212 F and 0 psig.VIEW DETAIL
