The Nagaon Pulp and Paper Mill (Assam, India) produces 100,000 tonnes of paper annually from bamboo. The mill is surrounded by a vast spread of agricultural land on all sides excepting the southern side, which is covered with hills and deep forests. The present study was undertaken with a view to assess the impact of the paper mill operations on the quality of the surrounding …
An improved coal pulverizer classifying system including a classifier cone extension to protect coal flow into the pulverizer from the annular fine-lifting airflow from the pulverizer throat. The classifier cone extension replaces traditional intermittent discharge structure, improving flow through the classifier system and reducing the disruptive effects of the discharge on the …
Coal from travelling belt of raw coal feeder drops in central feed pipe ( connection between Raw Coal Feeder and Mill). After coal reaches Mill bowl grinding started and hot air also been given to make the pulverised fuel dried enough to classifier chamber. The portion of the coal which cannot be grinded finds its way to mill reject.
In a coal-fired power plant having an exhauster fan for delivering coal/air flow through a discharge chute to a combustion chamber and further having a riffle box in the discharge chute, a mixing device located in the discharge chute between the exhauster fan and the riffle box for causing heavy and light distribution regions of the coal/air flow from the fan to …

Abstract The aim of present study is to clean the dye contaminated wastewater in an efficient and environmentally affordable manner using coal fly ash, a waste by-product of thermal power plant. Initially, the low densities, inert and hollow cenospheres were segregated from coal fly ash which are blended with chitosan in 3:10 stoichiometric ratio via …
In this study, basic co-firing characteristics of pulverized coal and ammonia were investigated using a bench-scale single burner test furnace. A schematic diagram of the single burner test furnace is shown in Fig. 1. The rated thermal input of the furnace is 760 kW, which corresponds to approximately 100 kg/h of coal for common bituminous coals.
