Product Description
The new VII water-fire tube steam (VI hot water) boiler is a new eco-friendly and energy-saving product co-developed by our company and Professor Li Zhiguang-a famous boiler expert, professor of Harbin Institute of Technology and director of Beijing Institute of Light Boiler after 30 years of study and experiments, adapting to the conditions of our country.It is called as a revolution of industrial boilers by domestic and foreign experts.Its main characteristics are as follows:
I.Sufficient and Steady Capacity
With efficient diabatic spirally corrugated tube, it is designed by using heat transfer and flow resistance technologies of Harbin Institute of Technology.The boiler's actual capacity is 10-15% higher than name plate capacity:As the physical dimension and smoke speed of the spirally corrugated tube are rational, and the spirally corrugated tube doesn't form soot or wear when the boiler normally operates, the boiler's capacity and heat efficiency don't reduce with the extension of operating time;
II.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;
III.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;
IV.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%;
V.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;
VI.Small Overall Dimensions and Low Boiler Room Investment Cost
The main heating surface is installed in the shell, and a boiler with less capacity can cancel the rear heating surface.Its overall dimension is obviously lower than other furnaces.The boiler below 100 steam tons (70MW) can be arranged in single layer, making the investment of the boiler room save more than 50% than other furnaces;
VII.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;
VIII.Short Installation Time, Low Installation Cost
The furnace is delivered after fast assembly, assembly and semi-assembly.Compared with other furnaces delivered after loose packing, its installation period and installation cost are reduced by over 30%.
