NJGC耐压式称重给煤机

　　Model NJGC Pressure Coal-Weighing Feeder

　　产品概述

　　NJGC耐压式称重给煤机适用于火力发电厂燃煤锅炉制粉系统，能在很大的负荷变动范围内改善锅炉性能，使过热温度、再熟温度和压力温度的控制更为稳定，使燃料所需空气更为匹配，所需的空气过剩量减少，连续给煤、称量准确、工作稳定、节能高效，是燃煤锅炉制粉系统中与磨煤机相匹配的先进的计量给煤设备。

　　Model NJGC Pressure Coal-Weighing Feeder app'icalbe for the milling system of the power plant.and it will highly enhance the boiler perfromance within a la rger load changing range. so that the over-heated.Hot temperature and pressure of the temperature control is more stable, and the needed air is more match the fuel, the excess amount of air will be reducedThe whole system is an avdanced weighing feeder device that match the coal crusher of the coal-firad boiler milling system for its hIgh product performance.high weighing accuracy.

　　工作原理

　　储煤仓中的煤通过煤闸门进入给煤机，由给煤机内部的输送计量胶带连续均匀的输送磨煤机中，在输送计晕胶带的下面装有电子称重装置，该装置主要由高精度电子皮带秤组成，称重传感器产生一个与煤的重量成比例的电信号和速度传感器检测到的皮带速度信号，同时送人积算器，经积算后得到瞬时流量和累计量。

　　结构特点
