Features

This product integrates two core technologies: "flue gas condensation waste heat recovery" and "low nitrogen oxide combustion"

Core advantages：
1.More energy-efficient, with low operating costs.By using a condensing heat exchanger, the sensible heat and latent heat released by the condensation of a large amount of water vapor in the flue gas can be fully recovered.
2.Low emissions, environmentally friendly and reliable.The boiler adopts advanced combustion technologies such as flue gas recirculation
3.System integration, easy installation:Quick installation modular design, compact structure

Main application scenarios

Key environmental protection areas and mandatory renovation projects:Factories facing the requirement of "coal to gas" conversion
High energy consumption, continuous operation processing and manufacturing industry:Food and beverage (sterilization, steaming), textile printing and dyeing (shaping, drying), chemical industry (reaction heating), medicine, rubber vulcanization, etc.
Commercial fields that require space and safety:Laundry rooms, kitchens, and central air conditioning heating in large hotels, hospitals, schools, and commercial complexes
Regional energy stations and distributed heating:Provide centralized steam or hot water for residential areas and parks.
As a high reliability process heat source:Industries with extremely high requirements for heat source stability, such as precision electronics, laboratories, and biological products.

Q&A

Q: This boiler is much more expensive than a regular gas boiler, why is it worth investing in?

A: This is an investment that pays for the future. The price difference mainly comes from expensive low nitrogen burners and corrosion-resistant condensing heat exchangers. The return lies in: 1) saving fuel: high thermal efficiency can save a lot of gas costs every year, and usually the investment difference can be recovered within 1-3 years; 2) Environmental compliance: To avoid the risk of fines or production shutdowns due to non-compliance with emission standards and ensure production continuity.

Q: How is the concept of "thermal efficiency exceeding 100%" achieved? Is it false advertising?

A: This is not false advertising, but a scientific calculation method. There are two calculation benchmarks for boiler thermal efficiency: based on the high-level heating value and low-level heating value of the fuel. The exhaust temperature of ordinary boilers is high, and the latent heat of water vapor cannot be utilized, so the efficiency is calculated at a low heating value of about 92%. The condensing boiler recovers this latent heat, and its effective utilization of heat exceeds the lower heating value of the fuel, resulting in an efficiency of "over 100%". This is the internationally recognized core indicator for measuring the energy-saving capability of condensing boilers.

Q: Do we need to handle the condensate ourselves? What are the requirements?

A: need The boiler will produce continuous condensate water. Due to its weak acidity, it cannot be directly discharged into ordinary sewers. There are usually three compliant treatment methods: 1) neutralize to pH 6-9 and discharge into the sewage pipeline network; 2) Collect and hand it over to qualified units for processing; 3) In some areas, emissions can be diluted with the approval of environmental protection departments. We will provide compliant emission plan recommendations based on your on-site situation.
