A computational model of ash removal process for dense-phase pneumatic pump conveying

Abstract: The ash removal mechanism of dense-phase pneumatic pump conveying was expounded completely and the situation of the design was analyzedThe irrational design parameters selection of ash conveyor system with a fluidized pump was revealedBased on the power index minimization of pneumatic ash removal system,the parameters computational method was proposedThe computational model of critical flow velocity Vc,diameter of conveying pipe Dc and economic gas-ash transmission ratio μc was constructedThe comparison of the computational sump pumps pressure,the computational economic gas flow velocity and test results was analyzedThe results show that the computational model is reliable,reasonable and effectiveIt has an important reference for the design and management of pneumatic ash removal system in coal-fired power plant

Research on dust control of coal handling system in power plant

Abstract: By analyzing dust production mechanism in power coal handling system, optimal design method of dust pollution control in coal handling system was proposed. Coal quality and mill types were considered for distribution of screen and crusher facilities. For ball mill, the screen and crusher facilities may be canceled. New anti-deviation airtight guide groove and sprinkler water spray were combined to prevent dust for design of belt conveyor .The practice shows that the measures can reduce investment, operating expenses and dust pollution, which achieve the purpose of saving energy and reducing emissions in power plant.

A Development of Intelligent Dry Dust Removal Equipment for Coal and Ash Handling System of Thermal Power Plant

Abstract: Chinese energy structure is nowadays dominated by thermal power plants, while coal production and consumption are huge with large amount of water consumption and massive dust produce. Energy saving, water conservation and environmental protection have to be carried on. An intelligent dry dust removal equipment is developed, witch is driven by compressed air, jet Venturi tube is drawing air ash and coal dust on the ground, a cyclone separating filter is collecting the dust, second level collection is the cloth filter, SO2 and CO2 filtration and purification are from solid adsorbent filter at outlet. It realizes zero water consumption and emission for handling the dry dust. The intelligent dry dust removal device is more energy saving, flexibility and easy to use.
