1000Kgs Industrial Biomass Steam Boiler Used For Rice Mill Boiler
The DZL new design water-fire tube boiler is a new eco-friendly and
energy-saving product co-developed by our company and famous Harbin
institute of Technology and director of Beijing Institute of Light
Boiler.
1. Rapid Warming and High Heat Efficiency
The main heating surface is installed in the shell, so it doesn’t
leak cold air to the smoke side, and nearly a half of shell surface
is heated. The boiler’s heating up time is one third shorter than
other furnaces, and heat efficiency is the highest in various
furnaces;
2. Low Original Dust Discharge Concentration, Environmental
Protection and Energy Conservation
It uses new arch and hearth with large volume, the rear of the
hearth has a dust separation reversing chamber, and the unburned
dust particles fall to the hearth for secondary combustion,
corresponding to primary dedusting in the furnace. Therefore, it
ensures that the original dust discharge concentration is lower
than national permissible value, reducing fuel consumption, and
protecting the environment;
3. High Steam Quality
The optimally designed feeding apparatus reduces overhigh water
level in shell high temperature zone due to overheat; the optimally
designed steam separator facilitates vapour gravity separation, and
makes the steam humidity lower than 1%, obviously lower than
national standard of 4%;
4. Strong Water Quality Adaptability
By adopting the advanced water circulation technology, it improves
water circulation speed of high temperature zone, increases the
flow of bottom water, and avoids sundries deposition and scaling,
with stronger water quality adaptability than other furnaces,
reducing fuel consumption, and improving operating time;
5. Small Overall Dimensions and Low Boiler Room Investment Cost
The main heating surface is installed in the shell, and small
capacity boiler can cancel the rear heating surface. Its overall
dimension is obviously smaller than other boilers. The boiler below
100tons (70MW) can be arranged in single layer, making the
investment of the boiler room save more than 50% than other types;
6. Low Operating Cost, Safety and Reliability
The adoption of advanced water circulation technology and
optimization of boiler structure improve the operating conditions
of the high temperature tube plate, water wall tube and shell
bottom. In normal water quality condition, it doesn’t cause tube
explosion, tube plate cracking or shell bottom bulge. As the boiler
has large water capacity, it doesn’t need special protective
measures in sudden power failure, and prevents damage accidents of
heating surface and shell medium due to vaporization. The safe
reliability is guaranteed, and operating cost is far lower than
other furnaces;
7. Short Installation Time, Low Installation Cost
There are fast-delivery, assembly and semi-assembly type delivery
model. the installation period and cost can be lower by over 30%.
