介绍了一种全新的燃烧系统——熔融盐循环热载体无烟燃烧技术.对以甲烷为燃料,Fe2O3为氧栽体,质量比为1:1的Na2CO3和K2CO3的混合物为熔融盐的循环热载体无烟燃烧技术透平做功系统与以甲烷为燃料的常规燃烧技术透平做功系统进行了比较.结果表明,利用熔融盐循环热载体无烟燃烧技术不但可以容易地对CO2进行回收利用,减少温室气体CO2的排放量,还可使燃料的火用利用效率有所提高.
A power plant based on nonflame combustion technology using thermal cyclic carrier of molten salt can offer two kinds benefit for us:One is easy to separate the greenhouse gas CO2,the other is a possibility of high net power efficiency. The fuel is oxidized by an oxygen carrier instead of being oxidized by oxygen from the combustion air. In this paper, NFCT utilizes methane as a fuel,Fe2O3 as oxygen carrier and 1 : 1 weight ratio of Na2CO3 and K2CO3 mixture as molten salt. Nonflame combustion technology using thermal cyclic carrier of molten salt gas turbine(GT) was compared with the conventional combustion of methane gas turbine(GT). The net power efficiency of the NFCT is higher than for the corresponding GT systems with conventional combustion. If we could utilize the physical exergy remaining in the exhaust in an efficient way,the net power efficiency of NFCT systems could be even further increased.
