Patent number: 9518730Abstract: A large-size circulating fluidized bed boiler, comprising: a furnace having a vertical furnace center line; and at least two groups of cyclones, each cyclone of each group of cyclones having an inlet gas pass communicated with the furnace. A furnace cross section formed by outer sidewalls and located at the inlet gas pass of the cyclone is a polygon having 2×n sides, and n is a positive integer greater than 1. The polygon is axially symmetric with respect to a perpendicular bisector of each side of the polygon, and when n is 2, the polygon is a square. Triangles formed by two endpoints of an inlet of the inlet gas pass of each cyclone at the cross section and an intersection of the furnace center line and the cross section are congruent. A single flow field in communication with each of the inlet is formed in the cross section.Type: GrantFiled: January 19, 2012Date of Patent: December 13, 2016Assignee: Institute of Engineering Thermophysics, Chinese Academy of SciencesInventors: Qinggang Lu, Ming Gao, Yunkai Sun, Guoliang Song, Xiaofang Wang, Yongjie Na, Dongyu Wang, Haigang Wang

Patent number: 8067620Abstract: A means and method for treating malaria, schistosomiasis, and cancer using a spiro or dispiro 1,2,4-trioxolane is described. The preferred 1,2,4-trioxolanes include a spiroadamantane group on one side of the trioxolane group, and a spirocyclohexyl on the other side of the trioxolane group. In comparison to artemisinin semisynthetic derivatives, the compounds of this invention are structurally simple, easy to synthesize, non-toxic, and potent against malarial parasites. The compounds of the invention unexpectedly provide a single-dose cure for malaria, as well as prophylactic activity against the same. The compounds are also active against schistosomiasis and cancer.Type: GrantFiled: October 31, 2007Date of Patent: November 29, 2011Assignee: Medicines for Malaria Venture MMVInventors: Jonathan L.
