As petroleum resources become more costly and less plentiful, alternative forms of energy are being considered. Composite fuels, of which coal-oil mixtures is the most common, have received relatively minor attention until now even though it is the one alternative utilizing existing technology. Industrial boiler demonstrations of COM fuel are being performed by the Department of Energy and a number of private firms. Ideally, COM can be handled by the same equipment currently used by No. 6 oil systems. Environmental and operating problems occur, due to the coal portion of the mixture, but these are being quickly resolved. Paper published with permission.

: It is estimated that more than 500,000 industrial boilers (mostly stoker-fired) in China consume over 400 million tons of coal per year. Because of low efficiency (only 60-65 percent) of industrial boilers, the energy consumption and pollution emissions from industrial boilers rank second place in China’s industry. On the other hand, China is rich in bamboo resource, and bamboo forest area is more than 5 million hectares, and occupies more than 1/4 of the world’s total. However, the common utilization rate of bamboo timber’s physical processing is below 40% in weight, over 60% of bamboo timber becomes left over when processed. Bamboo wastes, compared with coal fuel, are a very clean and renewable and sustainable energy. Therefore, there is the requirement that coal fired industrial boiler change its fuel into bamboo wastes in China, and some suggestions for bamboo fired boiler are presented in this paper. It is well economy of bamboo fired boiler in the region of China where an abundance of bamboo wastes disposed.

Abstract The value of the Department of Energy (DOE)-owned national laboratories to the U.S. national innovation system has long been a subject of debate. Advocates have drawn attention to the central role of the labs in the development of technologies including advanced batteries, solar energy breakthroughs, imaging technologies, and various IT endeavors, among others. Critics have recurrently suggested that the labs’ innovative capacities have been undermined by a lack of engagement with commercial firms and managerial tactics. Perhaps surprisingly, what has often been missing from the debate is a thorough review of data on the public-private partnerships in which the labs engage with private firms. This paper draws on heretofore non-public data on one type of contractual arrangement - Work-For-Others (WFO) agreements - in which the labs perform contract work for private firms. We review 10 years of WFO data for a single DOE laboratory. Our analysis provides an initial picture of the surprisingly diverse geography and array of firms that employed the labs as contract R&D providers, as well as of key characteristics of these agreements. Although our data capture only a single laboratory’s agreements, the findings reinforce the importance of looking at the complex, overlapping network of programs within the U.S. federal system that support private sector innovation.

Semibatch Reactor

Pyrolysis is the one solution to recycle hydrocarbon-based waste material such as used lubricant and cooking oil. The aim of this research was to determine the effect of temperature and sample ratio on the liquid yields of a mixture of used lubricant and cooking oil. The semibatch reactor was used with a constant nitrogen flow rate of 5 mL/min. Three different ratios of sample mixture were applied in this experiment: 0.5:1, 1:1, and 1.5:1, and three different temperatures: 4000C, 4500C, and 5000C. The thermal pyrolysis of a mixture of used lubricant and cooking oil was deemed as the most effective pyrolysis to produce liquid fraction was obtained from reaction condition with the sample mixture ratio of 0.5:1 at 5000C. At this reaction condition, the liquid yields was 58.90% which consist of 64.12% were C1-C3 and 29.54% were C5-C15.  Liquid fraction is predicted to increase as the temperature increase and the ratio of used lubricant to cooking oil decrease. When the ratio is increased , more gas fraction is produced.

The purpose of this paper is to examine the pressure drop caused by placing an airfoil at different angles of attack in the straight part of the rectangular air duct, as the first step of investigating the possibility of using a staggered cascade of airfoils for gradual deflection of the airflow in radial elbows of an air supply system used in industrial boilers. The initial problem was approached by using the commercial CFD code based on the Finite Volume Method (FVM) to numerically simulate a 2D incompressible turbulent flow and by conducting direct experimental measurements in the wind tunnel. The results of CFD simulations have been compared to experimentally measured data for two considered cases of inlet velocities and five different angles of attack. Numerical solutions show an adequate level of agreement with experimental measurements. The obtained results indicate the possibility of using a staggered cascade of airfoils for gradual deflection of the airflow.

AbstractThis article is devoted to the issue of the enforceability in Russia of arbitral awards rendered pursuant to arbitration agreements between Russian companies or state agencies, on the one hand, and private firms operating outside of Russia, on the other. The emphasis is on the enforcement of arbitral awards rendered outside of Russia. Russian statutory law, international treaties to which Russia is a party and Russian court practice are discussed. The enforceability of foreign judicial decisions, as opposed to arbitral awards, in Russia is also briefly discussed.

Abstract Aside from the scientific value of the method described here for the catalytic dehydrogenation of monoölefins to diolefins, the present contribution has an important industrial, commercial, and military value, viz., as an economic source of raw material for synthetic rubber. The production of butenes from butanes and pentenes from pentanes has already been described. The present paper, showing the production of butadiene from butenes and isoprene from pentenes, is the connecting link between the billions of cubic feet of butanes present in natural and cracked gases and of butenes present in the latter, and the billions of gallons of pentanes available in natural gasoline and crude oil on the one hand, and the production of synthetic rubber from these raw materials on the other. The basic raw materials for the production of synthetic rubber therefore now include our tremendous resources of hydrocarbon oils, hydrocarbon gases, and coal to produce synthetic hydrocarbons, if and when our petroleum resources become exhausted. The production of synthetic rubber from butadiene and isoprene is well known. Wallach exposed isoprene to light and produced synthetic rubber. Matthews and Harries independently used metallic sodium to polymerize isoprene to rubber. Similar work has also been done bv others.

This article focuses on the estimation of a proper logarithmic damping decrement in industrial boilers when flue gases travel in the vertical direction. The structure for this type of facility is quite unified worldwide. The structural conception is rather simple, and the response to any static loading is predictable. Nevertheless, with regard to dynamics and damping, some specifics in the detailed solution make this system unique. For the purpose of this analysis, a Plexiglas scale model was prepared at a geometric scale of 1:20. A set of experimental modal analyses was performed on the model. Each test focused on the damping effect of specific details and compared it with the common structure without a damping effect. Finally, a site modal analysis was conducted on an actual boiler located in the CHP Torun Plant in Poland. The upper part of the structure was reinforced to have a horizontal deflection of 8 mm and was suddenly released. The resulting movement was recorded with an HD camera linked to a theodolite. Experimental results on the scale model of the actual structure confirmed that damping of this type of structure is significantly higher than that considered for common steel structures.
