When the oil-fired boiler has rated steam parameters, rated feed water temperature, uses design fuel and ensures thermal efficiency, the gas production per hour of a 4-ton oil-fired boiler is the boiler tonnage. For example, under the rated state, the gas output per hour of a 4-ton boiler oil-fired boiler is 4 tons.
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 still the following formulas for calculating the hourly gas output of a 4-ton boiler oil-fired boiler, which can roughly calculate the steam volume:
1. Calculate the amount of steam according to the amount of fuel;
In this method, the calculation formula for the hourly gas production of a 4-ton boiler oil-fired boiler is: boiler steam volume = fuel calorific value / (evaporation heat per ton of steam + heat required per ton of water to rise from normal temperature to 100 degrees) * boiler thermal efficiency
2. Statistics of water supply flowmeter;
In this method, the hourly gas production of a 4-ton boiler oil-fired boiler can be considered as follows: boiler steam volume = water supply volume
3. According to the pressure during stable operation, according to the burner nozzle controlled by the pressure control switch, check the hourly fuel injection volume of the nozzle, which can also be roughly obtained, and then convert the steam volume;
In this method, the calculation formula and method 1 of the gas production per hour of the 4-ton boiler oil-fired boiler are basically the same.
4. According to the back pressure of the feed pump, check the flow head diagram of this kind of pump, and get the hourly flow data, which can be roughly calculated.
In this method, the hourly gas output of a 4-ton boiler oil-fired boiler is: boiler steam volume = water pump flow rate = under the root number (theoretical lift of the pump - actual lift) / internal friction of the pump
5. Measure the flow rate and temperature of exhaust smoke in a stable section to obtain the flow rate of smoke and steam, and convert the amount of steam. This method is more complicated to calculate and is generally not commonly used.
