Condensing ultra-low nitrogen vacuum boiler/condensing integrated vacuum boiler

2020-07-11

Product Introduction:
The condensing integrated vacuum boiler is different from ordinary boilers. The thermal efficiency of this boiler is designed uniquely to reduce the emission of harmful substances. On the basis of ordinary boilers, a flue gas heat recovery device is added, which is compact in structure. By absorbing high-temperature flue gas and low-temperature return water, the heat conversion efficiency is improved, gas costs are saved, and the thermal efficiency of the boiler is fully utilized. The boiler is equipped with ultra-low nitrogen combustion engines, which make it more efficientThe emission of NOx is ≤ 30 ㎎.
The Fushide condensing integrated vacuum boiler series has been tested by Henan Boiler and Pressure Vessel Safety Testing and Research Institute, and a boiler energy efficiency test report has been issued: boiler thermal efficiencyUp to 103%, exhaust temperatureAs low as 75 ℃， NOx emissionsBelow 27.5 ㎎/m ³.
The overall design of the boiler body and condenser saves 50-70% of the floor space compared to other heating products. Compared with the indirect heating form (boiler+external heat exchanger+circulating water pump+material+installation cost), the installation cost is saved by more than 30-40%, with high efficiency, fast heating, good heat exchange, and fuel cost savings of more than 20-30% compared to other heating products; Through unique design, the emission of harmful substances is reduced, and the thermal efficiency of the boiler is fully utilized. The boiler is equipped with ultra-low nitrogen combustion engines, resulting in NOx emissions ≤ 30 ㎎.
Vacuum boilers always operate under negative pressure, without the risk of expansion and explosion, and have the safety and reliability of normal pressure and pressure boilers;
The overall efficiency of the machine is over 98%, and it can provide 70-80 ℃ hot water within 2-3 minutes after startup, greatly shortening the preheating period and reducing energy waste. If a smoke temperature waste heat recovery device is added, the thermal efficiency will be greatly improved;
The built-in carbon steel (or stainless steel) heat exchanger has high heat transfer efficiency and clean water quality. The large furnace core technology effectively increases the radiation heating area of the unit, reduces NOX emissions, and the smoke tube is equipped with a winding plate to enhance heat transfer efficiency and make the structure more compact;
The integrated design of boiler and heat exchanger saves space and greatly reduces the footprint;
Fully automatic control system, no need for dedicated personnel to monitor, with inlet/outlet temperature display function, making it more convenient to grasp the operation status of the boiler and system;
Adopting advanced centrifugal glass wool multi-layer insulation with minimal heat loss, the overall spray coating has a compact and beautiful appearance;
The successful separation of the high-temperature and high-pressure zones of the boiler's load-bearing steel plate extends the boiler's service life by 2-3 times, with a designed service life of up to 30 years.
