Condensing boilers use high-efficiency chillers and energy savers to absorb the sensible heat in the high-temperature flue gas exhausted by the boiler and the latent heat released by the condensation of water vapor to achieve the purpose of improving the thermal efficiency of the boiler.
The body is a wet-back three-return, full-corrugated furnace tube, and a threaded flue pipe structure, which has good thermal scalability.
The tube sheet and the cylinder adopt a flange connection structure. The main welding seam of the body is a butt structure, and all welding seams are completed by submerged arc automatic welding.
Ample heating area, large furnace structure, slightly positive pressure combustion, low combustion heat load, and low emissions of harmful substances.
The boiler combustion chamber has a reasonable design and is fully adapted to various fuels such as city gas, natural gas, light diesel oil, and heavy oil.
The boiler's smoke blackness, smoke dust blackness, concentration, noise and other technical indicators are better than national first-class regional standards.
High thermal efficiency: The radiant heating surface of the boiler is a full corrugated furnace tube, and the convection heating surface uses a threaded flue pipe. The heating surface is large, and the boiler thermal efficiency is more than 105%, which is higher than relevant national regulations.
High welding quality: The main longitudinal and circumferential welds of the boiler are heat treated after welding according to JB / T1613 to eliminate stress and ensure welding quality. Automatic welding equipment to ensure the qualified rate of flaw detection.
The appearance is beautiful and novel: The boiler outsourcing uses colored steel plates, and the hinged smoke box is used on the front and back. The surface is painted with high temperature, which is novel and beautiful.
Use of high-quality accessories: It adopts international famous brand burners such as Italy Riya Road, Italy Black, Italy Olympia. The supporting key valves and instruments adopt domestic high-quality products or internationally renowned brands, such as Germany's Siemens, France's Schneider, Japan's Omron, etc., which effectively ensure the safety of boiler operation.
PLC full intelligent control system: The company has a fully-automatic PLC intelligent control system independently designed and developed, and fully owns intellectual property rights. It adopts the combined control method of mechatronic control equipment and programmable logic controller (PLC).
Take the programmable logic controller (PLC) as the "central processing unit" of the control system. The control system operates through the touch screen, which greatly improves the degree of automatic control and operation reliability of the boiler, and the operation is simpler and more intuitive.
The working principle of condensing boiler: The exhaust temperature is one of the basic parameters of the boiler. Selecting a lower exhaust temperature can reduce the exhaust loss of the boiler and help improve the boiler's thermal efficiency. If the boiler exhaust temperature drops to a sufficiently low level, the superheated water vapor in the flue gas will condense and release the latent heat of vaporization. Condensing boilers use high-efficiency flue gas condensing waste heat recovery devices to absorb the sensible heat in the exhaust smoke at the tail of the boiler and the latent heat released by condensation of water vapor to achieve the purpose of improving the thermal efficiency of the boiler.
