  • The problem of applying of the system of reverse osmosis

    The higher the salt content of feed water, the higher the value of continuous purging of steam boilers and the higher the gas overspend. Since reverse osmosis desalts water, the value of continuous purging, as a rule, is lower than 1% of the boiler's steam capacity and, accordingly, can be provided by periodic purging of the steam boiler.Learn More

    Computations were carried out for an assumed boiler efficiency of 80%, time constant of 1 minute, burner purge time of .5 minute, and damper delay time of .5 minute. Steady state cooling losses were estimated from measurements to be 1.5% and 0.5% of the …Learn More

  • The monitoring of the water-chemical mode of low-pressure

    The method contains the following steps. Boiler water from the continuous purge line of the steam boiler 1, passing the shut-off valve 2, enters the water-water refrigerator of the sample 3, in which the boiler water is cooled to 10-30°C by supplying cooling water.Learn More

  • Blowdown in Boiler | Boiler Blowdown Calculation Formula

    Blowdown in Boiler Definition. Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.Learn More

  • How to Destroy a Boiler -- Part 1

    Purge, purge, purge! Low-Water Conditions The potential for severe and even catastrophic damage to a boiler as a result of low-water conditions is easy to imagine considering that furnace temperatures exceed 1,800°F, yet the strength of steel drops sharply at temperatures above 800°F.Learn More

  • Minimize Boiler Short Cycling Losses

    The post-purge performs a similar function. During purging, heat is removed from the boiler as the purged air is heated. Example A 1,500 hp (1 hp = 33,475 Btu/hr) boiler with a cycle efficiency of 72.7% (E 1) is replaced with a 600 hp boiler with a cycle efficiency of 78.8% (E 2). Calculate the annual cost savings. Fractional Fuel Savings = (1 Learn More

  • Inert Gas Purging Requirement Calculation

    boiler operating at a 4:1 turndown would have to run for a significantly shorter amount of time to produce the same amount of energy in steam or hot water to the system. The actual time that it would have to operate can be simply calculated by: 4 Full load * 10 Full load 1 * 4:1 Btu/hr t Btu/hr hr = Therefore: .4 or 24min 10 4*1 4:1 hr hr t = =Learn More
