Condensing Gas Fired Boiler Introduction
- Condensing gas fired steam boiler, as the name implies, is a condensing gas fired steam boiler. The most important of condensing gas boilers is the realization of condensing technology. It is a new energy saving and environmental protection technology. Its principle is not complicated, the simple summary is to recover the heat energy in the flue gas by condensing it.
- In a traditional boiler, the exhaust temperature is generally 160~250℃ or even higher, so that the water generated by fuel combustion (such as natural gas: CH4+2O2→CO2+2H2O) in the flue gas in the superheated state of water steam, along with the flue gas from the chimney loss. The thermal efficiency of conventional boilers can only reach 85%~91%. Condensing gas-fired boiler can reduce the exhaust temperature to 50~70℃, fully recover the sensible heat in flue gas and latent heat of condensation of water vapor, and greatly improve the thermal efficiency.
- Condensing gas fired boiler working principle is through a certain device will be the hot flue gas after the boiler combustion emissions (generally at about 140 ℃) of energy recycling, after recycling the exhaust temperature of 60 ℃ or so, thermal efficiency is increased about 10%, so naturally to save about 10% of the gas, in the process of energy recovery at the same time, also can reduce the emissions of harmful gas, reduce the pollution of the environment.
Condensing Gas Fired Boiler Advantages
1. Advanced and reasonable design, safe and reliable performance
WNS type boiler body is of wet-back three-way, full ripple furnace and threaded smoke tube structure, with good thermal retractability. The tube-plate and tube-barrel adopt bevel edge connection structure, the main weld of the body is butt structure, and all adopt submerged arc automatic welding.
2. Abundant heating area, large furnace structure
- The gas fired boilers micro-positive pressure combustion, low combustion heat load, less harmful substances emissions.
- The boiler combustion chamber design is reasonable, fully adapt to urban gas, natural gas, light diesel oil, heavy oil and other fuels, fuel in the furnace micro positive pressure combustion, complete combustion, less smoke pollutants, boiler smoke blackness, smoke blackness, concentration, noise and other technical indicators are better than a regional standard.
3. High thermal efficiency
- The radiant heating surface of the boiler is a full corrugated furnace tube.
- The convection heating surface is made of a threaded pipe with a large heating surface.
- The boiler’s thermal efficiency is above >95%, higher than the national regulations.
4. High welding quality
- The main longitudinal and girth welds of the boiler shall be heat-treated according to JB/T1613 after welding to eliminate stress and ensure welding quality.
- Automatic welding equipment to ensure 100% pass rate of flaw detection.
5. Beautiful and novel appearance
- The condensing gas fired steam boilers is outfitted with colored steel plates, and the front and back are hinged smoke boxes.
- The industrial boilers surface is painted with high temperature, which is novel and beautiful.
6. Use quality accessories
- The burner adopts international famous brand burner.
- The supporting key valves and instruments are made of high quality famous products and international famous brands to ensure the safe operation of boilers.
7. PLC intelligent control system
- Mechatronics control equipment and programmable logic controller (PLC) combined control mode is adopted.
- Advanced programmable logic controller (PLC) as the control system of the “central processing unit”.
- The control system is operated by touch screen, which greatly improves the degree of automatic control and reliability of operation, and makes the operation more simple and intuitive.
