Product Description:
It adopts D-type arrangement, natural circulation, double-bottle water tube boiler, longitudinal arrangement of the boiler cylinder, full membrane water-cooled wall structure, and micro-positive pressure combustion.
Furnace is covered by membrane wall, flue gas from the furnace outlet into the convection tube bundle connected between the upper and lower boilers, flue gas flow through the convection tube bundle, into the tail heating surface - steel spiral fins economizer, condenser.
Product Advantages:
1,Scientific design, reasonable structure. Membrane water-cooled wall is adopted to improve the rigidity of the furnace chamber and flue, and improve the anti-explosion capability of the boiler wall; explosion-proof door is set in the explosion-prone part to prevent the destruction of the furnace wall by deflagration. The main weld of the body is butt joint structure, and all of them are welded by submerged arc automatic welding.
2,Well-developed processing equipment and advanced production technology. The company has international advanced large-scale joint-span steel structure production plant, with good lighting and reasonable layout. The supporting production equipment is well-equipped and complete, with more than 1,100 sets of various types of equipment, 400KVA and other types of flaw detection equipment, etc.; the production of the products adopts advanced CNC undercutting and milling, submerged arc automatic welding and xenon arc welding, pipe plate welding and other new technologies and new techniques to ensure the quality of the products.
3,High degree of automation, reliable operation of equipment. Adopt electromechanical integration control equipment and programmable logic controller (PLC) joint control mode. Advanced programmable logic controller (PLC) for the control system "central processor". Control system through the touch screen operation, so that the degree of automatic boiler control and operational reliability greatly improved, the operation is more simple and intuitive.
4,Long life, sufficient output, high efficiency. Scientific product design, advanced processing technology, rigorous quality control, all the boiler equipment produced by the factory continuous operation life of up to 10 years or more. Boiler radiant heating surface for the full corrugated furnace gallbladder, convection heating surface using threaded pipe, large heating surface, boiler heat output is sufficient, the thermal efficiency can be as high as 92% or more than the national regulations.
