2.Summary
India JPL 2 × 660MW power plant #1、#2 boiler, each boiler is equipped with 6 numbers HP1163/Dyn type medium-speed mill-type bowl. Corresponding to the mill, there are same numbers of raw coal bunkers. The effective storage capacity of the 6 bunkers could satisfy the consumption of coal for more than 8 hours at BMCR condition when worst coal is burnt according to the EPC contract. The top of the bunker is square steel structure; the bottom of it is a square-conical type.There is air blast generator breaking coal choking for each raw coal bunker to prevent coal block at the outlet of the metal raw coal bunker.Each mill is equipped with one gravimetric type belt coal feeder with frequency converter motor, which could adjust the amount of coal to follow the load requirement of boiler.The coal chutes at inlet and outlet of the mill are made of stainless steel, so it is much convenient for the coal to flow, at the same time, it can be more wearable.
