The influence of BaCO3 on chlorine fixation and combustion characteristics was investigated in a fixed bed system and thermal analyzer. Both simulation and experimental results show the stability of BaCl2 was much better than CaCl2 at temperature higher than 800°C. The chlorine fixation of cotton stalk was improved 5.35 times by BaCO3. The barium chlorides in the ashes were mainly BaCl2 and Ba(ClO...
To study the influence of organic montmorillonite (OMMT) on the yield stress of the model waxy oil (LMO) under dynamic cooling, OMMT was prepared through ion exchange of the sodium montmorillonite with dimethyldioctadecylammonium chloride (DOAC). The incorporation of OMMT lead to a great reduction of the yield stress, which could be explained by the inhibition effect of OMMT on the wax gelation. For...
Detailed speciation analysis has been conducted on the corroded tubes coated with two different ash deposits collected from the combustion of a lignite, namely Xinjiang coal mixed with and without external silica in both air- and oxy-firing modes. The exposure conditions are of temperature of 650°C, 50h and the use of different flue gases (i.e. pure CO2, air, air-firing flue gas and oxy-firing flue...
The influence of the nano-hybrid pour point depressant (NPPD) on flow properties of waxy crude oil was studied. Rheological results showed that NPPD demonstrated better improvement in viscosity, yield stress and pour point reduction for crude oil than the conventional polymer PPD (N6) did. Moreover, the viscoelastic behavior data showed that the NPPD doped oil had a weaker gel network structure at...
The mechanisms governing the behaviour of limestone for in-furnace desulphurisation during oxy-fuel combustion have been investigated in this paper. Apart from the use of pure limestone, the mixtures of limestone with a brown coal (i.e., lignite) at different mass ratios have also been examined to address the influence of ash on the behaviour of limestone. The combustion experiments were conducted...
Oxy–fuel combustion of a brown coal (i.e. lignite) has been carried out at 1000°C to experimentally examine the vaporisation of organically bound metals and the agglomeration of ash particles as a function of the concentration of gaseous impurities including H 2 O, HCl and SO 2 in ∼27% O 2 balanced with CO 2 . The properties of bulk ash and individual metals were investigated...
