The chain grate boiler is a horizontal three-pass water-fire tube hybrid boiler, Chain grate with a bunch of threaded smoke tubes arranged in the drum. The left and right sides of the furnace are equipped with light pipe water cooling walls. Boiler introduction: The chain grate boiler is a horizontal three-pass water and fire tube hybrid boiler, Chain grate with a bunch of threaded smoke tubes arranged in the drum. The left and right sides of the furnace are equipped with light pipe water cooling walls. It adopts light chain grate to realize mechanical coal feeding, equipped with blower and induced draft fan for mechanical ventilation, Chain grate and equipped with scraper type slag discharger to realize automatic slag discharge.
The front and back arch of the furnace adopts a new type of energy-saving technology arch. The fuel falls from the coal hopper to the grate, and after entering the furnace to burn, Chain grate the flame refracts upwards through the back arch and turns upwards through the combustion chambers on both sides of the body to the front smoke box, Chain grate and then folds back from the front smoke box to the tube bundle in the pot, and passes through the rear smoke box Enter the economizer, Chain grate and then be drawn by the induced draft fan through the flue to the chimney and exhausted to the atmosphere.
Performance characteristics: The boiler thermal efficiency is above 77%, which is higher than the standard of "General Technical Conditions for Industrial Boilers". The operation has been mechanized, Chain grate which reduces the labor intensity of the firemen. Quickly install and leave the factory. After arriving at the site of use, Chain grate install valve instruments, blowers, induced draft fans, flue ducts, economizers, dust collectors, Chain grate and slag dischargers. The coal machine and water circuit can be operated, and it has the characteristics of quick start and fire. Easy to install and move can save a lot of capital investment. Burning coal, Chain grate the second-class bituminous coal with low calorific value ≥17750J/Kg, volatile matter>38.5%, and ash content ≤32.4%.
