The Benefits of Converting Waste Heat to Power | AltEnergyMag

A steam turbine generates electricity as a byproduct of steam production unlike a gas turbine or a reciprocating engine CHP system where heat is a byproduct of power production. Steam turbine-based CHP systems are typically used in industrial processes where biomass coal or waste products are available to fuel the boiler unit.

Effect of petroleum (pet) coke addition on the density and ...

May 01 2013 · Pet coke has a density of approximately 1350 kg/m 3 when measured at 26 ± 2 °C by He picnometry (model Micromeritics Accupyc 1330) and this is much lower than that of the hydrated cement paste matrix (1900 kg/m 3). At 30% addition paste volumetric densities were reduced by 15% for all size fractions of pet coke.

Boiler Wikipedia Republished // WIKI 2

Input Output Method (Direct method) Direct method of boiler efficiency test is more usable or more common. Boiler efficiency = power out / power in = (Q * (Hg - Hf)) / (q * GCV) * . Q = rate of steam flow in kg/h. Hg = enthalpy of saturated steam in kcal/kg. Hf = enthalpy of feed water in kcal/kg.

Jun 05 2016 · In boilers firing pet-coke there is the formation of (V 2 O 5) or (V 2 O 4) which also causes agglomeration. Some practical options for reducing agglomeration are: In case of biomass co-fired boilers one can limit the percentage of biomass as per design of the boiler to reduce the risk of agglomeration [22] .
