Abstract Biomass is one of the world’s greatest sustainable energy potentials. Utilization biomass in form Co-firing coal fuel with alternative to reduce dependence fossil fuels towards green power plant. This paper addresses Co-Firing modelling test results up 50% using palm kernel shell (palm shell) Ketapang Coal Fired Power Plant (CFPP) 2x10 MW. CFPP has circulating fluidized bed (CFB) boile...

Air caps are an effective way of ensuring uniformity air flow in Circulating Fluidized Bed (CFB) boilers. Published literature on the design and configuration these is severely limited. In this study, extensive theoretical as well experimental investigations have been carried out to novel order improve efficiency CFB A small-scale test bench 220 t/h boiler has developed, integrated with caps. I...

China's coal-dominated energy structure will not change in a short time. In order to implement the relevant national policies on conservation and emission reduction, it is good response adopt circulating fluidized bed boilers coal-fired power stations. Circulating boiler adopts combustion, which has high reliability utilization rate because of its special combustion mode particle recycling devi...

This work studies the identification and control of circulation fluidized bed (CFB) boilers. The CFB boiler under investigation shows strong nonlinearity due to big changes of steam load. A linear parameter varying (LPV) model is used to represent the process dynamics and used in control. The steam flow is used as the working-point variable (scheduling variable) of LPV model. Multivariable plan...

The production of synthetic natural gas (SNG) via methanation has been demonstrated by experiments in bench scale bubbling fluidized bed reactors. In the current work, we focus on scale-up reactor, and a circulating (CFB) is designed with variable diameter according to characteristic methanation. critical issue removal reaction heat during strongly exothermic process As result, an interconnecte...

In advanced energy process technologies, like the advanced pressurized circulating fluidized bed (CFB) process conceptualized by Foster Wheeler Corp., there exists a need to transport and control the flow of solids from a high pressure vessel to a low pressure vessel. Solids transport has long been done in the refinery industry and in the CFB combustor industry, but always from a low pressure v...

Vanadyl pyrophosphate (VPP) is the active catalytic phase that converts n-butane to maleic anhydride in fixed beds, fluidized and DuPont’s circulating bed (CFB). The original CFB concept was based on Mars van-Krevelen reaction mechanism which solid lattice contributes all of oxygen partially oxidize n-butane. However, maintain high activity selectivity requires surface oxidized; thus, DuPont co...

N2O emissions from coal fired fluidized-bed combustion are approximately 30–360 mg/Nm, much higher than that from pulverized coal combustion (less than 30 mg/Nm). One approach to reduce the N2O is to reburn the biomass gasification gas in the coal-fired fluidized bed. In this paper, the effects of gasified biomass reburning on the integrated boiler system were investigated by both simulation an...

This work compares the transient behaviors of flue gas sides large-scale bubbling and circulating fluidized bed (BFB CFB, respectively) boilers. For this purpose, a dynamic model in-furnace side combustors presented validated by authors in former is used to simulate two industrial units. The results show that for load changes heat transfer waterwalls stabilizes more rapidly BFB Differences stab...

The fluidized bed combustion (FBC) of biomass and solid recovered fuel (SRF) is globally emerging as a viable solution to achieve net-negative carbon emissions in the heat power sector. Contrary conventional fossil fuels, alternative fuels are highly heterogeneous, usually contain increased amounts alkaline metals chlorine. Hence, experimental studies mandatory order thoroughly characterize beh...
