1.The technology is composed of several modular units(combustion and heat transfer).
2.Each modular unit adopts high-efficiency micro-negative pressure and premixed combustion technology;
3.It is equipped with a secondary heat exchanger to fully absorb the sensible heat and latent heat of high temperature flue gas;
4.It is equipped with a secondary air preheater to fully absorb exhaust heat and combustion chamber outward conduction, radiation loss heat;
5.Intelligent automatic control system is adopted to realize accurate and time-division heating and avoid excessive or insufficient heating.
1.Energy saving -- reduce operating costs by 15%~30%
Energy-saving building, underfloor heating, gas consumption ≈ 5Nm3/ 5 months.m2
2.Environmental protection - ultra-low nitrogen oxide emissions
NOx ≤ 25mg/m3 / CO≤60mg/m3
3.Safety -- Safe and reliable, with "0" explosion risk
Atmospheric pressure boiler, no need for boiler record, security check
4.Intelligent -- Intelligent network control (PC/Mobile terminal)
Rs485 communication protocol, centralized monitoring
5.Silent - "no" work noise Work noise≦50dB
6.Outdoor - protection grade IP65, small size, light weight
Different from the traditional combustion machine boiler in structure, it has a furnace without a pot (not a pressure vessel), and level 1 and level 2 heat exchangers are connected by waterways with all pipes, and the water is hot as soon as it passes water. It can withstand the higher transmission pressure of the closed cycle system (the pressure is 13Kg/cm before delivery), and it is equipped with multiple safety protection. The product does not belong to the scope of annual security check of the traditional boiler.
Thermal efficiency of 105%-106%(according to high calorific value), exhaust gas temperature is not higher than 50℃(underfloor heating), the chimney can be made of PVC pipe (corrosion resistance).
The products have passed the national expert group energy conservation technical appraisal organized by China Quality Certification Center (CQC), and obtained the "Certificate of Energy Conservation Technology" (Certificate No. Cqc-jnjsrd-1510). It has also been selected into the Reference Catalogue of Energy conservation and Water saving Technology Products of Public Institutions by the Department of Energy Conservation Management of Public Institutions of the National Government Offices Administration. Compared with ordinary combustion boiler, it saves 25-40% of gas and 40-60% of electricity cost.
Nitrogen oxides emitted by air pollutants for the boiler is NOx≤25mg/m , CO≤60mg/m.
Working noise is less than 50 dB，which conforms to the limiting value of equivalent sound level in Standard of Environmental Noise of Urban Area, in living area (Ⅱ class), the noise shall be no more than 60dB during the day and no more than 50dB at night.
Through highly intelligent means, the boiler can realize the constant energy-saving operation mode and the precise automatic control of heating throughout the whole process, truly achieving unguarded, replacing full-time duty with equipment inspection, better solving the boiler operation and management problems, with labor cost greatly reduced.
With the help of high-tech Internet of Things technology, the operation state of each boiler can be remotely monitored through PC or mobile phone, and the setting of boiler's start, stop and operation parameter can be remotely controlled through authorization.
It has very strong market competitiveness in application cost, investment payback period, operation and maintenance cost, etc.
Under the conditions of normal operation, regular maintenance, adequate soft water treatment, air dust filtration and sufficient air supply in boiler room, the service life shall not be less than 20 years.
The rapid production mode of modular products, parts standardization, assembly streamlined makes the batch production cycle greatly shortened, the fastest delivery can be 2 days, and the longest delivery period in peak season shall not exceed 20 days, which can meet customers' fast and flexible shipping demands.
