Effect of the radiation heat loss on propagation of the spherical flame through premixed coal dust
An analytical study has been conducted to investigate the effect of radiation heat loss on the spherical flame propagation in coal–dust clouds. This research can be valuable in the development of alternative fuels; and it can be used by the fire safety and control industry. The model includes the evaporation of the volatile matter of dust particles into a known gaseous fuel (methane) and the ...

Carbonization of johkasou sludge using batch-type equipment
The carbonization of dehydrated johkasou sludge was examined using batch-type equipment. Based on the temperature changes in the carbonization room and the gas combustion room, the carbonization process was divided into three phases: phase I, drying the sludge, phase II, thermal decomposition of the dried sludge, phase III, after phase II. The times required for phases I and II were strongly ...

Quantifying Combined Heat and Power (CHP) activity
In CHP plants without heat rejection facilities power, output is complementary to the recovery of heat, and all activity is cogeneration. CHP plants with heat rejection facilities can operate a mix of cogeneration and condensing activities. Quantifying the energy flows of both activities properly requires knowledge of the design power-to-heat ratios of the CHP processes (steam and gas turbines, ...

Exergy analysis of natural gas/DME combustion in homogeneous charge compression ignition engines (HCCI) using zero–dimensional model with detailed chemical kinetics mechanism
In the present work, a single zone combustion model with detailed chemical kinetics is developed to study the effect of dimethyl ether (DME) concentration on the combustion of natural gas from second law point of view in a homogeneous charge compression ignition (HCCI) engine. The code can predict all exergy terms in the cylinder with crank angle during a closed cycle. The chemical kinetics ...

The landfill gas collection, utilisation and surplus gas combustion acting in unison
In landfill gas utilisation the basic task of the control system is to harmonise three completely independent processes. On the one hand, there is the gas production of the landfill which is inconstant. (From a price point of view, hardly worthwhile to store the gas in a gasometer) On the other side the independent gas utilisation process, which orientates itself to the requirement of the ...

Problems of catalytic boiler safety and their role in designing and operation of gas-fired boiler
In the following paper, some problems of safety for catalytic boilers with fixed and fluidised beds are discussed. The reason is to protect the boiler from gas and fuel-air mixture explosion. For it the conditions excluding the transition from catalytic combustion to flame must be observed, and they are presented in the article for different combustible gases. A special attention has been paid to ...

Pyrolysis Machine - How Exactly Does Pyrolysis Machine Work?
Together with the world currently facing an international waste problem, we have seen a heightened need for more potent waste management technologies. Many of the global waste ends up piled up in landfills, incinerated, or in our water ways and oceans. As you already know, all of these methods have proved to be ineffective in dealing with the situation and also have even resulted in more ...
