1 Water softenerThis device thoroughly removes substances in raw water that increase the water hardness and cause scale to adhere to the boiler without troubling users. The high-performance water hardness leakage sensor strengthens reliability by regularly checking the water hardness when water is passed and immediately switching the water softener to another one if water hardness leakage is detected.

2 Feedwater tankFeedwater deaeration and boiler water supply are automated. Of course, an opening for drain recovery is provided and can be used together. The tank is made of stainless steel, which is resistant to rust.

3 Nitrogen gas type deoxygenation deviceUtilizes a method to blow in nitrogen gas into the water and remove other gases. When water contacts nitrogen gas, dissolved oxygen in the water moves to air bubbles of the nitrogen gas that have a lower oxygen partial pressure.

4 Chemical feeding equipmentBy injecting a water treatment chemical (Thermo Fresh), this device treats scale and a s light amount of substances increasing the water hardness that cannot be treated by the water softener.

5 Pure chemical ThermofreshThis pure chemical for (simplified / compact / large) once-through boilers prevents various failures and troubles caused by water and supports their stable operation for a long period of time.

6 Carbon dioxide pH neutralization deviceDelivers superior performance in pH treatment of boiler blow-down water. A proprietary technique of controlling the inside of the pipe provides a high mixing rate, and easy operations and maintenance are realized. In addition, this space-saving device can easily be installed both indoors and outdoors.

7 Automatic measurement and multiple unit control panelFor multiple boilers, this device properly controls operation of each boiler according to the steam load.

Notes: 1. The actual evaporation is the value for the saturated steam at 15°C feedwater temperature and 0.49MPa steam pressure. 2. The boiler efficiency value is calculated by the heat loss scheme provided in JIS B 8222-1993. However, the calculation is made under the following conditions. 0.49MPa steam pressure, 15°C feedwater temperature, 35°C charge air temperature 3. The margins of error are as follows: • Boiler efficiency error: ±1% • Combustion capacity error: ±3.5% 4. The fuel consumptions are calculated based on the following fuel lower calorific values: LNG： 40.6MJ/m³ (N) Propane： 93.7MJ/m³ (N), 46.4MJ/kg Butane： 118.9MJ/m³ (N), 45.7MJ/kg5. Install the gas piping so as to ensure a sufficient feed gas pressure, even while the boiler is running, stopped, or other gas equipment is being operated. Supply gas pressure: 0.03 to 0.3MPa

6. The main unit of the boiler come with an economizer. Be sure to set the feedwater temperature to 50℃ or higher.7. If the feedwater temperature is high when, for example, collecting the drain water, fuel consumption may be reduced as the standard of actual evaporation.8. The diameter of the safety valve discharge outlet shown between parentheses applies piping for blowing outdoors.9. Maximum combustion capacity (input) is computed based on the standard lower calorific value.10. The silencer for the flue is included as standard. The position to connect the flue is the outlet of the silencer for the flue.

Combustion with super low emissions reduces burden to the environmentIn combustion at a low fuel-air ratio in which air supply for combustion is tightened, reducing emissions of CO and NOx has been extremely difficult with conventional techniques. The jet film combustion technique, however, contributed to achieving super low emissions which are at NOx= 25ppm and CO=30ppm levels in combustion at a low fuel-air ratio. This is a revolutionary gas emission performance that greatly surpasses existing combustion technologies.

Super high efficiency & reduced electricity consumptionCombustion at a low fuel-air ratio contributed to achieving industry leading boiler efficiency of 98%. Tightening air supply for combustion means that there is no need to heat redundant air exceeding the amount of air necessary for combustion, leading to improvement in boiler efficiency.With combustion at a low fuel-air ratio, energy consumption for operating the blower has been reduced by 10% as compared with conventional products. In addition to this, the inverter controls the number of rotation according to the boiler load, which largely reduces energy consumption for the blower during a low load operation. Saving fuel and electricity consumption contributes to reducing CO2 emissions as well as operation costs.

Notes: 1. The actual evaporation is the value for the saturated steam at 15°C feedwater temperature and 0.49MPa steam pressure. 2. The boiler efficiency value is calculated by the heat loss scheme provided in JIS B 8222-1993. However, the calculation is made under the following conditions. 0.49MPa steam pressure, 15°C feedwater temperature, 35°C charge air temperature 3. The margins of error are as follows: • Boiler efficiency error: ±1% • Combustion capacity error: ±3.5% 4. The fuel consumptions are calculated based on the following fuel lower calorific values: Fuel oil A: 42.7MJ/kg, density 0.86g/cm3

Kerosine: 43.5MJ/kg, density 0.80g/cm3

5. For fuel oil A, use JIS Class 1, No. 1, which contains 0.5 mass% sulfur or lower.6. The main unit of the boiler come with an economizer. Be sure to set the feedwater temperature to 50℃ or higher.7. If the feedwater temperature is high when, for example, collecting the drain water, fuel consumption may be reduced as the standard of actual evaporation.8. The diameter of the safety valve discharge outlet shown between parentheses applies piping for blowing outdoors.9. Maximum combustion capacity (input) is computed based on the standard lower calorific value.*1. The type display is as follows

Comparison of highly efficient systems


Comparison of running costs


Comparison of CO2 emissions

The efficiency of the combustion type boiler itself has already been improved to the highest level.F-nex, which utilizes a combination of a highly efficient heat pump and conventional boiler system, evolves into a highly efficient boiler system.

Heating low-temperature feedwater by its own steam causes a large energy loss.F-nex supports the sensible heating range up to 60℃ to enable the facility to improve its efficiency.

The electric type heat pump technique realizes over three times higher efficiency than that of the combustion type.In addit ion to this, i t reduces CO2 emissions and provides eco-friendly energy.
