NJGC耐壓式稱重給煤機

　　Model NJGC Pressure Coal-Weighing Feeder

　　產品概述

　　NJGC耐壓式稱重給煤機適用于火力發電廠燃煤鍋爐制粉系統，能在很大的負荷變動范圍內改善鍋爐性能，使過熱溫度、再熟溫度和壓力溫度的控制更為穩定，使燃料所需空氣更為匹配，所需的空氣過剩量減少，連續給煤、稱量準確、工作穩定、節能高效，是燃煤鍋爐制粉系統中與磨煤機相匹配的先進的計量給煤設備。

　　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

　　儲煤倉中的煤通過煤閘門進入給煤機，由給煤機內部的輸送計量膠帶連續均勻的輸送磨煤機中，在輸送計暈膠帶的下面裝有電子稱重裝置，該裝置主要由高精度電子皮帶秤組成，稱重傳感器產生一個與煤的重量成比例的電信號和速度傳感器檢測到的皮帶速度信號，同時送人積算器，經積算后得到瞬時流量和累計量。

　　結構特點

　　圓筒形密封結構，提高耐壓力，減少內部粉塵堆積;

　　采用性能卓越的ST2、ST4系列電子皮帶秤，確保計量準確和長期穩定;
