An inverse method for flue gas shielded metal surface

In this case, an emissivity correction is necessary to derive the real temperature. Moreover, in a coal-fired power plant, the metal surface of superheaters and reheaters is shielded by a radiative participating flue gas, which is a mixture of CO 2, H 2 O, CO, NO x, fly ash and soot particles.

Inline sulphuric acid concentration measurement

The concentration of sulphuric acid (H2SO4) is calculated from conductivity and temperature measurements. The measurement provides sulphuric acid concentration as % or g/l without on site development work. We also provide oleum (SO3) measurements for sulphuric acid plants and users.

Optimization of particle size distribution in circulating

Among the factors affecting the performance of the CFB boiler, the particle size distribution (PSD) of coal gangue feed was found to be the most significant. This has been reflected by that only a slight variation in the average diameter of coal feed can impact the stability of both the crush system and CFB system significantly [ 9, 10 ].

Calculating Boiler Efficiency - Forbes Marshall

In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred. Calculation of direct efficiency- E= [Q (H-h)/q*GCV]*100. Q= Quantity of steam generated (kg/hr) H= Enthalpy of steam (Kcal/kg) h= Enthalpy of

Corrosion in boilers - Lenntech

Corrosion is the reversion of a metal to its ore form. Iron, for example, reverts to iron oxide as the result of corrosion. The process of corrosion, however is a complex electro chemical reaction and it takes many forms. Corrosion may produce general attach over a large metal surface or it may result in pinpoint penetration of metal.
