This paper presents numerical simulations of premixed combustion of low calorific value gases (LCVGs), providing a description of the flame characteristics in a tubular flame burner. The investigated gaseous fuels were methane diluted with nitrogen, simulating LCVGs with different heat values by regulating quantity of nitrogen. The flame shape and thermal field are consistent with experimental results. It consists of two segments of different feature, the lengths of which dependent on inlet velocity. Comparative study of flow fields at cold and thermal states were carried out with an aim to gain further understanding of the flow/flame interaction in the tubular burner. Heat release from combustion diverts the main pressure gradient to axial direction, thereby tangential velocity drop tends to close with axis of swirling, and axial velocity distribution changes to be trapezoid-shaped. Changing in low heat values influences the burning positively, while the flow does not exert an apparent effect.

Passive safety is a design concept for fast reactors. An analysis code to perform thermal-hydraulic calculation in passive Direct Reactor Auxiliary Cooling System (DRACS) was developed through the coupling of thermal-hydraulic response in Direct Heat EXchanger (DHX) model, Air Heat EXchanger (AHX) and circuits of DRACS. After steady-state initialization, a transient starting from air damper opening at the instant of reactor scram was simulated. Key parameters, such as mass flow rate in intermediate loop under natural circulation, heat removed by DRACS, air temperature at AHX outlet, coolant temperature at both side of DHX, are calculated, which preliminary showed the effectiveness of the code. As part of the system analysis code development for the pool-type Liquid Metal Fast Breeder Reactor (LMFBR), the newly developed code is now ready to be incorporated into System Analysis Code for pool-type Fast Reactor (SAC-CFR) to perform the interactive response between the DRACS and the whole system after scram.

Two stage biomass fixed bed gasifier has the advantage of lower tar content and higher calorific value of producer gas. This paper presented design and experimental investigation of a 190KWe (nominal) pilot scale biomass fixed bed gasifier using a double air stage downdraft approach. Wood chips were used as feedstock. The results demonstrated that due to the secondary air supply, a temperature as high as 900oC in the oxidation zone for a better tar cracking. Use of both stirrer and reciprocating grate avoided bridging and channeling. A direct connection of the gasification chamber and charcoal cooling chamber could minimize gas storage space to avoid deflagration. The average value of the composition was about 16.6% (CO), 2.3% (CH4), 16.1% (H2), 13.8% (CO2) and 0.4% (O2) whereas the average calorific value was 4.7MJ/ Nm3. The maximal LHV was 5.28 MJ/ Nm3 when the frequency of draft fan and secondary air supply were 45 Hz and 54 Nm3/h respectively.

Charging station, as one of the most important aspects of electric vehicle industry, must be able to adapt the fast development of electric vehicles. In this work, a hybrid solar-wind powered charging station was designed to provide electricity for the electric vehicles according to the wind and solar condition of the coastal areas in Tangshan. The key components including wind turbines, PV modules, batteries, an inverter and other controllers were considered. In order to determine the capacities of the components, LPSP was used as a control condition to obtain the configurations achieving the demand energy and the costs of every configuration as the other control condition were calculated to optimize the system. At last, the minimum-cost configuration achieving the demand energy was found as the result of the designation.

The steam temperature at the outlet of the reheater has always been lower than the designed value in a power plant. A reheat steam temperature adjustment test was conducted on the two subcritical, intermediate reheat and natural circulation boilers in the power plant. By analyzing the test data, reasons of the low reheat steam temperature have been discovered. What's more, three schemes about capacity-increasing transformation for reheaters have been proposed and compared, after which the most reasonable one is selected. What is studied in the paper provides helpful experiences in solving similar problems for boilers of the same type.

The aim of this study was to achieve the optimum process parameters for fuel ethanol production from corncob. After the optimization of orthogonal experiment, the process configuration including dilute acid pretreatment and separated saccharification and fermentation (SHF) by fed-batch strategy was obtained. The optimum conditions of pretreatment were that corncob was treated with 1.1% sulphuric acid and solid-to-liquid ratio=l:8 at 120°C for 3hours. After delignification with alkaline, water insoluble solid of 180g·L-1 were hydrolyzed with cellulase loading of FPA (IU·mL-1): CBA (IU·mL-1)=20:7 to per gram substrate at 48 °C and initial pH5.0. The maximum ethanol concentration from enzymatic hydrolysates fermented by Zymomonas mobilis at 35°C for 48hours reached 57.8g·L-1.

The combustion processes of refuse derived fuel (RDF) under oxygen-enriched atmosphere were analyzed by thermogravimetry and the combustion characteristics of RDF were studied (the effect on the combustion characteristics of RDF by factors including plastic content, heating rate and oxygen concentration). Studying the combustion characteristics of RDF can provide important basis for the design and selection of combustion equipment. Meanwhile, the combustion activation energy and frequency factor were obtained by Doyle method, then the combustion model of RDF under oxygen-enriched atmosphere was established. This study provided essential basis for the spread and oxygen-enriched combustion of RDF technology.

Coal pitch water slurry (CPWS), which was a new concept presented by the author, was prepared by adding coal pitch powder into the solutions of dispersant at high stirring rate. The particle size distribution of coal pitch powder followed the Alfred particle size distribution. The effect of slurry concentration with different amount of dispersants on rheological properties of CPWS was investigated in this paper. The results showed that the apparent viscosity of different concentration of CPWS decreased with the increase of shear rate and indicated that CPWS is a kind of pseudo-plastic liquid. At the same shear rate, apparent viscosity increased with the increase of CPWS concentration.

Heat transfer in coal seam is very important for the underground coal gasification process. A model test for studying the heart transfer rate and temperature variation rate in lignite block, isotherm distribution and temperature gradient around the hot coal wall was carried out. The test results show that the heat transfer rate and temperature variation rate in the coal seam are very small, while the temperature gradient is very large, all these phenomena is closely related with the permeability of the coal seam. Which suggest that we should consider the performance of heat transfer in the coal seam to control the velocity and direction of the flame transfer in the coal seam during the underground coal gasification, which is significant for obtaining high quality syngas steadily.

In the Photovoltaic(PV) power system, lighting intensity and air temperatur have great effect on the output characteristic PV cells which has distinct nonlinear characteristics. In this paper an improved method of perturb and observe (P&O) is proposed, based on the comparison of power, and then the simulation model on the platform of matlab/simulink is established. In comparison with traditional variable step-size P&O and InCond, this strategy can achieve better performance, and in the steady-state conditions it leads to lower oscillations and fewer power loss around the maximum power point. The improved method provides a quick and accurate tracking even in the conditions of irradiation change and it is proved to be a good method to realize the MPPT controlling of PV cells.
