North American cattle tick see boophilusannulatus. Service Alliance Inc. was called in to do one of our Heating Plant Efficiency Inspections for a prospective Client with high fuel bills. We came across a situation where the Two-Stage Oil Burner A drive that writes write-once optical discs such as CD-Rs and DVD-Rs. A "burner" implies a one-time recording, but the term is erroneously used to refer to drives that "write" to re-recordable CD-RW and DVD-RW/+RW media as well. See burn, CD-R and DVD-R. installed on the Cast-Iron Weil McClain Boiler boiler, device for generating steam. It consists of two principal parts: the furnace, which provides heat, usually by burning a fuel, and the boiler proper, a device in which the heat changes water into steam. was improperly fired. While the burner could "technically" be used in this application, its fire rate had the capacity to go beyond the rating of the boiler. SO as a result of poor maintenance practices, the spray nozzle A spray nozzle is a device that facilitates the formation of spray. When a liquid is dispersed as a stream of droplets (atomization), it is called a spray. The typical purpose of the spray is to maximize the effect of the liquid by increasing the total surface area for better installed had a rate twenty percent higher than the boiler was designed for. This condition became immediately apparent when we installed an exhaust gas Exhaust gas is flue gas which occurs as a result of the combustion of fuels such as natural gas, gasoline/petrol, diesel, fuel oil or coal. It is discharged into the atmosphere through an exhaust pipe or flue gas stack. thermometer thermometer, instrument for measuring temperature. Galileo and Sanctorius devised thermometers consisting essentially of a bulb with a tubular projection, the open end of which was immersed in a liquid. in the boiler stack. The temperature was twice as high as it should be. (Permanently installed thermometers are a great, low tech way to monitor boiler efficiency, they cost about $250.00 installed) As a rule of thumb, exhaust gas should be no greater than 150 degrees higher than the boiler water temperature. (NOTE: water turns to steam at 212 Degrees + 150 = Maximum exhaust temperature of 362 degrees.) In this case the boiler exhaust gas temperature was over 700 degrees. Our NEW client opted to replace the 2 stage oil burner with a fully modulating, variable capacity oil burner that permits firing at many different rates rather than just one high and one low setting. This is especially useful in the summer when the oil burner can be set to a very low fire simply to make hot water. NASA NASA: see National Aeronautics and Space Administration. NASA in full National Aeronautics and Space Administration Independent U.S. Technicians thoroughly cleaned the boiler sections and made some minor control modifications that allow the burner automatically adjust the size of the fire with the heating demands of the building. This resulted in a long, steady, high efficiency firing of the boiler. Resulting fuel savings will pay for the new burner install in less than nine months. Additionally, our new client took our advise and scheduled monthly combustion efficiency testing to assure that the heating equipment is at peak efficiency at all times.
