steam generator NBS-36KW-0 09Mpa amd superheater NBS-36KW-900℃

Short Description:

Determination of effect and dryness after high-efficiency steam-water separation


The dryness of the steam indicates the degree of moisture entrained in the steam, a measure value of 0 means 100% water content, and 1 or 100% means dry saturated steam, that is, no water is entrained in the steam.
Steam with a dryness of 0.95 refers to a mixture of 95% dry saturated steam and 5% condensed water.
The dryness of steam is necessarily related to the latent heat of steam. The steam with 50% latent heat energy at saturation pressure has a dryness of 0.5, which means that the steam is a 50:50 mixture of water and steam.

Steam is dry saturated only when it has all of its latent heat, and its dryness is 1.
Based on the influence of steam dryness on calorific value, the measurement of dryness value can estimate or calculate its dryness by measuring the energy or heat contained in steam at a specific pressure through simple calorimetry.
If the steam contains 10% water by mass, the steam has a dryness of 90%, that is, the dryness is 0.9.
Therefore, the actual wet steam evaporation is not the hfg shown on the steam table, but the actual evaporation is the product of dryness x and hfg.Dryness = actual evaporation stew/evaporation stew
Since the state of condensate in steam is uncertain, the sampling position of steam dryness is in the middle, bottom, or top of the steam supply pipe. Due to the moisture film on the inner wall of the pipe or the different states of condensate accumulation and suspended water droplets at the bottom of the steam pipe, the dryness error may exceed 50%.
The sampling position of the steam dryness after the high-efficiency steam-water separator is no longer strict. The dryness after the high-efficiency steam-water separator is increased to dry saturated steam, and the total steam value contained in the steam should be equal to the steam value under the corresponding pressure. And use this to determine the treatment effect of the high-efficiency steam-water separator.
