The gas consumption of 10 tph gas-fired boiler is related to technical parameters.
Such as heating surface layout, heat preservation effect, heat loss, water capacity, etc. The calculation formula of gas consumption of 10 tph gas-fired boiler is as follows:
=10 tph gas-fired boiler output÷ thermal efficiency ÷calorific value of natural gas
= 6,000,000 kcal ÷ 0.98 ÷ 8,600 kcal / h = 712 m3
Therefore, the gas consumption of 10 tph gas-fired boiler is 712 m3/ h
The gas consumption of the above gas-fired boiler is calculated at full capacity. In practice, the gas consumption changes with the operation load and operation conditions. In addition, if thermal efficiency of the gas-fired boiler is different, the gas consumption is different, too. The higher thermal efficiency is, the lower gas consumption is.
Loads vary, and a power plant must be capable of handling the minimum load, the maximum load, and any load variations. Boiler selection is often dictated by the variation in load demand, rather than by the total quantity of steam or hot water required. There are three basic types of load variations: seasonal, daily, and instantaneous.
All boilers, whether hot water or steam, depend on fuel to run. The heating process is initiated when the burner heats or evaporates the water inside it, which is ultimately transported via pipe systems. Hot water boilers rely on pumps to move the heat through the system, while steam boilers are transported with the pressure generated in the heating process. Eventually, cooled water or condensed steam is returned back through the pipes to the boiler system so that it can be heated once again. While the boiler is generating energy in the form of heat, flue gases, a byproduct of this process, are removed through a chimney system - which is why regulating the emissions of industrial boilers is taken very seriously.
The air in the economizer and condenser has not drained yet when firing. The safety valves of economizer and condenser need to be turned on to exhaust steam. Return pipe valves also need to be turned on, enabling the steam in the economizer and condenser to return to softened water tank.
The outlet water temperature is so high that economizer and condenser will have vaporization phenomenon. The outlet water temperature of economizer and condenser need to be controlled.
The check valve of the...
