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.

Coal Fired Boiler Emissions Test - EPA

2016-2-23·Unit One is a pulverized coal-fired, dry bottom boiler with an opposed firing configuration. Low NOx burners are used to control NOx emissions. Normal operating temperature in the combustion zone is approximately 2,000 - 3,000 degF. The boiler produces 4,500,000 lb/hr of steam for a General Electric steam turbine generator rated at 688 MWe.

Coal-mill optimisation in coal-fired power - EE

Many of the existing pulverised coal-fired (PCF) power stations are operated at a fixed steady load (i.e. baseload operation). There is however a growing requirement for load following or flexible operation, which requires flexibility in most of the components of the power station. Flexibility and efficiency can be improved by close control of the coal []

Updating for Ash Cooler Fluidized Air System of a 410

The paper presents an updating scheme for ash cooler fluidized air system of a 410 t/h CFB boiler. The ash cooler fluidized air, which is originally designed, is provided by the independent configuration of two forced fans. By analyzing and studying the operating data of the primary air and the ash cooler fluidizing air system at various

Sulfur Conversion of Mixed Coal and Gangue during

Downloadable! The construction of a power plant using a 660 MW e supercritical circulating fluidized bed (CFB) boiler with co-combustion of coal and gangue has been proposed in China. Therefore, this study simulated the distribution law and transformation mechanism of sulfur-containing phases using three low-calorific samples of gangue and coal mixtures under different conditions, based on the

Combustion Efficiency and Excess Air - Engineering

2020-5-8·The combustion efficiency increases with increased excess air - until the heat loss in the excess air is larger than the heat provided by more efficient combustion. Excess air to achieve highest possible efficiency for some common fuels: 5 - 10% for natural gas. 5 - 20% for fuel oil. 15 - 60% for coal. Carbon dioxide - CO2 - is a combustion

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 ].
