1. Conventional unit reference values are displayed in parallel with {}.
2. The above specification was based on the following values.
- Low calorific value of the fuel.
• Natural gas (13A): High/low calorific value 46.05/41.45 MJ/Nm { {11,000/39,900 kcal/Nm}}
• Propane : 101.74/93.7 MJ/Nm³ {24,300/22,380 kcal/N㎥} 50.37/46.39 MJ/kg {12,030/11,080 kcal/kg}
• Butane : 128.7/118.9 MJ/Nm³ {30,740/28,400 kcal/N㎥} 49.53/45.76 MJ/kg {11,830/10,930 kcal/kg}
• Boiler kerosene: Low calorific value 43.12 MJ/Nm { {10,300 kcal/kg}
- Gas combustion supply pressure will be supplied to 1.96 to 2.45 MPa (minimum 0.98 MPa) {200 to 250 mmH2O (minimum (minimum 100 mmH2O)}.
- If the gas supply pressure is 0.98 KPa (100 mmH2O), the diameter of the gas supply pipe may be changed.
- Condition for hot water supply: t40.
- Heating design flow conditions: t10
- Rated outputs for hot water and heating are used alone, and in the case of simultaneous use, the total is the tube heat output.
- Make sure that the inlet and outlet pipes of the heat exchanger are not constructed on the boiler.
- An expansion joint shall be installed at the inlet and outlet pipes of the heat exchanger.
- The specification table above can be changed without notice due to performance development, etc.
3. Boiler efficiency is based on low heat generation and the value at the right time.
4. As an inevitable measurement error, it contains the allowable values below.
- Boiler efficiency measurement error ±1%, combustion amount (heat input) measurement error ±1.5%.
5. Please understand that some changes without notice to develop the performance of the product.
