  • Boiler introduction

    The chain grate boiler is a horizontal three return water and fire tube mixing boiler, a bunch of threaded smoke pipe is arranged in the boiler barrel. The right and left sides of the furnace is provided with light pipe water cooling wall. The light chain grate is used to realize the mechanical fuel feeding, equipped with blower, induced draft fan for mechanical ventilation and the scraper type slag remover machine is used to realize the automatic slag removal. A new type of energy saving technology is adopted for the front and rear arch of the furnace. The fuel from the coal scuttle fall on the grate grate, into the furnace combustion, the flame passes through the rear arch to refract upward to the front smoke box, then back into the pot tube bundle, after the smoke box into the economizer, and then induced by the draught fan through the flue to the chimney to the atmosphere.

  • Product features

1. The boiler is the horizontal fast installation of water and fire tube boiler, working natural circulation.

The boiler heat exchange system is composed of drum, left and right header and water wall, the main heating surface is the furnace water wall, some of the drum and convection tube bundle in the drum.

2. Advanced design performance:

The drum is made of special steel plate for boiler, the left and right boxes are made of seamless steel pipes.

3. The boiler arch is made of refractory concrete. The back arch is low and long, so the combustion is good. The two wings of the flue and the side wall brick are made of refractory bricks. The boiler front wall, the back wall uses the general refractory brick.

4. The grate is designed reasonable for air distribution, the combustion chamber is large, suitable for all kinds of coal, mixed coal and biomass fuel, full combustion. Due to the high temperature flue gas into the settling chamber, and then from both sides into the flue, the former smoke box, and thus having good effect of smoke and dust removal.

5. Water cycle is simple, the structure of pressure parts is reasonable, in the case of ensuring the quality of water, safe operation.
