CDZL horizontal coal-fired hot water boiler

Product Introduction of 2015 New CDZL Horizontal Coal fired Hot Water Boiler

The DZL type chain grate boiler is a horizontal three return water fire tube hybrid boiler, with a bundle of threaded smoke tubes arranged inside the drum. There are light tube water-cooled walls installed on both sides of the furnace. A lightweight chain grate is used for mechanical coal addition, equipped with a blower and induced draft fan for mechanical ventilation, and a scraper type slag removal machine for automatic slag removal. The front and rear arches of the furnace adopt a new energy-saving technology furnace arch. The fuel falls from the coal hopper onto the grate and enters the furnace for combustion. The flame refracts upwards through the rear arch, passes through the combustion chambers on both sides of the main body, and then turns back to the front smoke box. It then returns to the boiler tube bundle through the front smoke box and enters the economizer through the rear smoke box. It is then drawn by the induced draft fan through the flue and discharged into the atmosphere through the chimney.
Performance characteristics:
1.boilerThe type is a horizontal quick installation water fire tube boiler with natural circulation of working fluid.
The heat exchange system of the boiler consists of a drum, left and right headers, and water-cooled walls. The main heating surfaces include the furnace water-cooled wall, some drums, and convective tube bundles inside the drums.
This product is composed of five main parts when it leaves the factory: boiler body, flue gas duct, economizer, dust collector, and pipeline system. The first four parts have been manufactured in the factory and transported to the installation site for assembly, which can greatly shorten the installation cycle and ensure the quality of product installation.
2 . Advanced design performance:
The main heating surface tubes of the boiler are made of seamless steel pipes for 20 # low and medium pressure boilers, and the drum is made of boiler specific steel plates. The left and right collection boxes are made of seamless steel pipes.
3. The boiler arch is made of refractory concrete and compacted. The rear arch is low and long, so it burns well. The two wings of the flue and the side wall bricks are made of refractory sintered bricks. The front and rear walls of the boiler are made of universal refractory bricks.
4. Reasonable grate air distribution, large combustion chamber, and strong applicability of coal types. Suitable for various types of bituminous coal, anthracite coal, and blended coal. Fully burned. Due to the fact that high-temperature flue gas first enters the settling chamber and then enters the two wing flue and front smoke box from both sides, the smoke and dust removal effect is good.
5. The water cycle is simple, and the structure of the compressed parts is reasonable. It can operate safely while ensuring water quality.
6. The combustion equipment is a quick installation grate, which is manufactured and installed in the factory. After transportation to the construction site, it can be directly installed on the foundation. With reasonable and compact structure and low steel consumption, the boiler's performance, weight and structural dimensions are obviously progressiveness compared with domestic products of the same capacity.

The working process of the boiler:
Coal blocks with roughly uniform particles are fed into the coal hopper by an automatic coal feederChain grateUnder the rotation, enter the preheating zone of the front arch. After burning out in the ignition zone, it falls into the slag pool. The high-temperature flue gas generated by furnace combustion enters the rear of the furnace through the arch mouth at the lower part of the two wing flue gas ducts, and then exchanges heat through the two wing flue gas ducts. It flows forward through the front smoke box, enters the convection tube bundle for heat exchange, and then enters the economizer, dust collector, and chimney through the tail of the drum. It is then sent to the chimney by the induced draft fan and discharged into the atmosphere.
The boiler feed water is completed by the boiler feed water pump, and the softened water enters the boiler drum through the feed water pipe economizer, and then enters the left and right headers through the downcomer. The water-cooled walls on both sides absorb heat and vaporize to produce steam. The steam enters the steam water separator inside the drum, and after separation, it enters the heating process through the main steam valve.
