DZL biomass horizontal hot water boiler is a horizontal three-pass water-fire-fire tube mixed boiler. Threaded smoke pipes are arranged in the drum. There are light pipe water-cooled walls on the left and right sides of the hearth. The light chain grate is used for mechanical feeding, equipped with blowers and induced draft fans for mechanical ventilation, and equipped with a scraper slag discharger to achieve automatic slag discharge. The furnace front and rear arches adopt new energy-saving technology furnace arches. The fuel falls from the hopper to the grate and enters the hearth for combustion. The flame passes through the rear arch refracted upward and passes through the embossing chambers on both sides of the body to the front smoke box, and then returns from the front smoke box to the inner tube bundle of the pot. The economizer is then drawn by the induced draft fan through the flue to the chimney and discharged to the atmosphere.
1. The boiler type is a horizontal quick-installed boiler, and the working fluid is naturally circulated. The boiler heat exchange system consists of a drum, left and right headers, and a water-cooled wall. The main heating surface includes a furnace water-cooled wall, a part of the drum, and a convection tube bundle in the drum.
2. Excellent design performance: The main heating surface tube of the boiler is made of 20 # seamless steel pipe suitable for low and medium pressure boilers, the drum is made of special steel plate for boilers, and the left and right headers are made of seamless steel pipes.
3. The boiler furnace arch is made of refractory concrete. The rear arch is low and long, and it burns well. The two-wing flue and side wall brick are made of refractory sintered brick. The front and back walls of the boiler are made of universal refractory bricks.
4. The grate is reasonable in air distribution, the combustion chamber is large, and the applicability of coal is strong. Adapt to all kinds of bituminous or anthracite, mixed coal. Burned fully. The high-temperature flue gas enters the sedimentation chamber first, and then enters the two-wing flue and the front smoke box from both sides, so the smoke and dust removal effect is good.
5. The water circulation is simple, the structure of the pressure parts is reasonable, and the water can be operated safely under the condition of ensuring the water quality.
6. The combustion equipment is a fast-installed grate. The combustion equipment is manufactured and installed in the factory and can be directly installed on the foundation after transportation to the construction site. With reasonable structure, compact and low steel consumption, the boiler performance, weight and structure size have obvious advantages compared with domestic products of the same capacity.
7. Energy saving and environmental protection: Adopting new gasification combustion technology, a gasification rotary combustion chamber is set up, and a secondary air distribution with swirl is built in to make fuel combustion more fully.
8. The use of high-efficiency heat transfer element-threaded flue pipe, with reasonable flue gas flow rate, makes the boiler thermal efficiency higher. Thermal efficiency is over 85%.
9. The boiler adopts the green renewable biomass wood pellet fuel promoted by the state, the CO2 reaches zero emissions, the smoke and dust emission concentration is less than 50mg / m3, the flue gas blackness is less than the Ringerman Class I, and all indicators have reached the national first-class regional environmental protection standard.
10. Low operating cost: Because the fuel (wood biomass particles) used by the boiler is a new environmentally friendly fuel supported by the state, it is a renewable resource. It has the characteristics of high heating value, low cost and wide source. Its operating cost is only one-fourth that of electric boilers and less than one-half that of oil-fired (gas) boilers.
11. High degree of automation: The digital integrated controller can automatically control the combustion conditions according to the user's setting. The operation is simple and convenient, automatic ignition, automatic loading, and automatic dust removal.
12. Safety: Adopting high standards and high-quality auxiliary machines, accessories and automatic control equipment to ensure the safe and stable operation of the boiler.
13. Novel appearance: The appearance design of the boiler is beautiful and generous.
