Abstract An experimental study presents a new innovative cyclone combustor, known as the three-way swirling combustion (TSC), utilizing non-pulverized wood biomass. The study shows that the combustor reached near-complete combustion, as evident in the measurements of CO and NOx emissions, and the excess air ratio. It also demonstrates the unique features of the TSC combustor, which includes an air curtain insulation effect with a high ash removal rate that reduces clinker and slag formation, alongside a chamber that does not need a refractory brick. It compares against conventional combustion technology, such as the stoker and the fluidized bed in terms of the amount of emission gases, maximum temperature, and excessive air ratio. Six geometrical and operational design criteria of the TSC for wood biomass combustion are identified for future work of design optimization. Ultimately, the implementation of the TSC for non-pulverized wood biomass and possibly for other biomass holds great potential for economically and technically beneficial incineration and power generation.

In order to understand the influence of the tensile stress on the corrosion of reinforcement bars in civil engineering, the reinforcement bars specimens were put into the liquid corrosion tank made of hydrochloric acid and distilled water by applying the tension stress on the reinforcing frame to carry out rapid corrosion. The corrosion of reinforcement bars under different tension stresses was tested by using electrochemical polarization method. The metallographic examination of reinforcement bars was carried out through the section of reinforcement bars. The corrosion mechanism of the stressed reinforcement bar was tested and analyzed. It can be known from the experimental study: First in the same corrosion condition, the larger the tensile stress is, the faster the corrosion of steel bar will be; Second corrosion current density or corrosion rate are index for evaluating corrosion rate of reinforcement bars with different tensile stresses. Corrosion potential can not be used as an index for evaluating corrosion rate of reinforcement bars with different tensile stresses; Third intercrystalline corrosion occurs inside the reinforcement bar due to micro-defects after rolling and moulding, which directly affects the mechanical properties of reinforcement bar.
