Random data of gas boiler
Natural gas boiler manufacturers need to provide but not limited to the following information:
1.Boiler quality certificate (including factory certificate, metal material certificate, welding quality certificate and hydraulic test certificate);
2. Boiler installation manual and operation manual;
3. Boiler drawing (including general drawing, installation drawing and main pressure parts drawing);
4. Strength calculation sheet or summary table of calculation results of compression components;
5. Calculation book or summary table of calculation results for safety valve discharge;
6. Factory information of safety accessories;
7. Information on major design changes of pressure components.
Gas consumption of 4 tons gas steam boiler
There are many formulas for calculating the gas consumption of gas boilers. The most commonly used formulas are based on the thermal efficiency of gas boilers, the calorific value of natural gas and the size of the furnace. Gas boiler gas consumption (per hour) = gas boiler power/time/fuel calorific value/gas boiler thermal efficiency can be calculated, which is simple and convenient. According to the common gas calorific value of 37MJ, the boiler power is 2.8MW. Calculated with a natural gas efficiency of 92%, the gas consumption of a 4-ton gas-fired steam boiler is around 296Nm3.
