Three alternative condensing mode power and combined heat and power (CHP) waste-to-energy concepts were compared in terms of their impacts on the greenhouse gas (GHG) emissions from a heat and power generation system. The concepts included (i) grate, (ii) bubbling fluidised bed (BFB) and (iii) circulating fluidised bed (CFB) combustion of waste. The BFB and CFB take advantage of advanced combus...

Solid Recovered Fuels made from commercial/industrial and MSW type waste streams containing high heat value plastics do offer a number of synergies for biomass combustors [1]. The paper covers technical and operational synergies to increase biomass combustion efficiency in a grate fired system typical for waste to energy technology. Results from small laboratory scale tests have proven a more s...

As the deployment of expert systems has spread into more complex and sophisticated environments, so inherent technological limitations have been observed. As a technique for overcoming this complexity barrier, researchers have started to build systems composed of multiple, cooperating components. These systems tend to fall into two distinct categories: systems which solve a particular problem, ...

This paper presents the results of theoretical studies process wear technological surfaces saw gin grates. Mathematical expressions are obtained, with help which it is possible to determine statistical characteristics raw roller and indicated that grate, in operation from impact roller, occurs as a result abrasive deposited on it. A rod model interaction between grate has also been studied, bas...

A technical analysis has been completed for a commercial-scale two-stage gasification-combustion system. The CLEERGAS (Covanta Low Emissions Energy Recovery GASification) process consists of partial combustion and gasification of as-received municipal solid waste (MSW) on a moving grate producing syngas followed by full combustion of the generated syngas in an adjoining chamber and boiler. This...

My Ph.D. dissertation (Jennings 1992a)1 develops and implements a new model of multiagent coordination, called JOINT RESPONSIBILITY (Jennings 1992b), based on the notion of joint intentions. The responsibility framework was devised specifically for coordinating behavior in complex, unpredictable, and dynamic environments, such as industrial control. The need for such a principled model became a...

As is well known, at present, saving electricity one of the priorities all types production where it consumed. Also, ways to improve efficiency products a low cost [1-3]. In cotton ginning industry, largest share purchasing bulk spare parts falls on gins and linters, in particular for purchase grates these two machines [4-6].

Mezzanine surfaces can be made from concrete, bar grate, or composite materials. Anecdotal data indicate that mezzanines in distribution centers made from composite materials, due to their increased compliance, may be a more comfortable working surface. Prior research suggested that a measure of tibial shock, peak tibial acceleration, could potentially discriminate the biomechanical differences...

When burning fuel in grate furnaces, supplying the right amount of air to them is as important method supply. In a furnace with fixed grate, supply primary determined by distribution supplied stream over time, and movable said involves along active length grate. The need account for attributable complex processes that occur during combustion process. paper describes experimental studies aimed a...
