The gas output of a 4 ton oil boiler per hour means how many tons of steam the boiler produces per hour. So how to determine the gas production per hour of a 4-ton oil-fired boiler in actual operation?
When the rated steam parameters, rated feed water temperature, design fuel and thermal efficiency are guaranteed, the gas output per hour of a 4-ton oil-fired boiler is the boiler tonnage. For example, at rated conditions, a 4 ton boiler produces 4 tons of gas per hour.
Generally, boilers are equipped with boiler steam flow meters, which can directly display the actual steam volume of the boiler. If there is no steam flow meter, there are several formulas for calculating the hourly gas output of a 4-ton boiler oil-fired boiler, which can roughly calculate the steam volume:
1. Convert according to the amount of fuel and steam;
In this method, the formula for calculating the hourly gas production of a 4-ton boiler oil-fired boiler is as follows: boiler steam volume = fuel calorific value / (heat required for the heat of vaporization of each ton of steam and water to rise from normal temperature to 100 degrees) * boiler thermal efficiency
2. Statistics of water flow meter;
In this method, the gas production per hour of the 4-ton boiler oil-fired boiler can be considered as: boiler steam volume = water supply volume
3. According to the pressure during stable operation and the burner nozzle controlled by the pressure control switch, check the fuel injection volume per hour of the nozzle, which can also be roughly obtained, and then convert the steam volume;
In this method, the formula for calculating the hourly gas production of a 4-ton boiler oil-fired boiler is basically the same as the first method.
4. According to the pressure behind the pump, check the flow head diagram of the pump to get the hourly flow data, which can be roughly calculated.
In this method, the hourly gas production of a 4-ton boiler oil-fired boiler is: boiler steam volume = water pump flow = root sign (theoretical lift of the pump - actual lift)/internal consumption of the pump
5. Measure the speed and temperature of the exhaust gas in the stable section to obtain the flow rate of the exhaust gas and convert it into steam. This method is computationally complex and is usually not commonly used.
The above is the calculation method of the hourly gas output of the 4-ton oil-fired boiler in different ways. I hope it will be helpful to everyone.
