The reaction mechanism of selective non-catalytic reduction on NH3-NO has been investigated experimentally in high temperature. The result has shown several basic conclusions: a) The reaction of NH3-NO is self-sustaining; b) oxygen must be involved in the reaction process of NH3-NO; c) Denitration reaction of NH3-NO in the temperature range centered at T1250K; d) the temperature window for NO removal moves to lower temperature, with adding hydrogen (H2) or hydrogen peroxide (H2O2) as well keeping the width of the window unaltered; e) the reaction is not explosive, and it takes place relatively smoothly in the course of approximately 0.1 sec.
The level of domestic gas utensils energy utilization efficiency decides the energy saving efficiency and economical efficiency of the gas utensils. In this paper, considering the stove-cooking utensil as the object of study, on the basis of deep research of stove-cooking utensil system’s high-effective heat transfer, high-effective heat preservation technology, combing the technology of high-effective burning, high-effective heat transfer, high-effective heat preservation, a stove-cooking utensil system that is of high-effective heat transfer, high-effective heat preservation, low cost, low exit flue gas temperature is designed and the stove-cooking utensil system’s energy efficiency is improved significantly by comprehensive designing and researching of the insulation lid, the bottom of pot, and the radiant panel on the condition of keeping high-effective burning.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
