Best Sale Easy Operation Fixed Grate Industrial Biomass Wood Fired Steam Boiler for rice mill

DZH type steam boiler is a kind of horizontal three return water - fire tube boiler.Rows of water wall tubes are arranged on the left and right sides of the furnace, and two groups of tubes are arranged in the drum to form two return trips. The heating surface of this type of boiler is sufficient and the economizer of the heating surface at the end is equipped., and equipped with drum, induced draft fan to achieve mechanical ventilation.Layered combustion.The coal has wide adaptability and good smoke elimination effect.Equipping with high efficiency cyclone dust collector, the concentration of smoke and dust discharge can meet the environmental protection requirements of the second class area.The smoke passes through the upper combustion chamber of the rear arch, from the combustion chamber upward through the rear shed tube smoke chamber into the first tube bundle to the front smoke box, and then from the front smoke box into the second bundle to the rear smoke box, through the induced draft fan pumping into the flue, dust collector and chimney, and finally discharged to the atmosphere.The boiler automation level is high, the boiler feed water automatic regulation, high and low water level alarm, low water level interlock protection, lead, fan interlock protection.Complete supporting auxiliaries.

This biomass steam boiler has high automation level, automatic adjustment of boiler feed water, high and low water level alarm, low water level interlock protection, and interlocking protection of lead and blower. Auxiliary auxiliary equipment is complete.

Structure

Performance characteristics:

1. The biomass fired boiler is a horizontal fast-installed steam boiler with natural circulation of working fluid. The steam boiler heat exchange system consists of a drum, left and right headers, and water walls. The main heating surface has a water wall in the furnace, and part of the drum and the drum have convection. Tube bundle. This series of steam boilers are composed of five parts when they leave the factory: the main body of the boiler, the flue duct, the dust collector, and the piping system. The first four parts have been manufactured in the factory and can be transported to the installation site for assembly, which can be greatly shortened Installation cycle, and can guarantee the quality of product installation.

2. High-quality boiler design performance: The main heating surface of the steam boiler is made of seamless steel pipes for 20# low and medium pressure boilers, and the drum is made of special steel plates for the boiler. The left and right headers are made of seamless steel pipes.

3. The steam boiler arch is made of refractory concrete. The back arch is low and long, so it burns well. The two-wing flue and side wall bricks are made of refractory sintered bricks. The front and back walls of the boiler are made of general-purpose refractory bricks.

4. The wood steam boiler grate has reasonable air distribution, large combustion chamber, and strong applicability of coal types. It is suitable for all kinds of bituminous coal, anthracite, and mixed coal. It burns fully. Because the high-temperature flue gas enters the settling chamber, it enters the two-wing flue from both sides, The front smoke box, so the smoke and dust removal effect is good.

5. The water cycle is simple, and the structure of the pressurized parts is reasonable, and it is completely safe to operate under the condition of ensuring water quality.

6. The boiler combustion equipment is a quick-installed grate. The combustion equipment is manufactured and installed in the factory and can be directly installed on the foundation after being transported to the construction site. It has a reasonable and compact structure and low steel consumption, which makes the performance, weight and structure of the boiler Compared with domestic boilers of the same capacity, the size has obvious advantages.
