Furnace level control as applied to gas producers
Gaseous fuel production requires a high degree of accuracy in the control of furnace levels. The levels in the furnace must be controlled precisely in order to achieve the correct temperatures, pressures and fuel-air mixtures for optimum performance. In this article, we look at the various approaches used to control furnace levels in gas producing furnaces.
The most common form of furnace level control is a mechanical one. This involves using mechanical devices, such as valves and regulators, to control the flow rate of the fuel to the furnace. The flow rate is adjusted according to desired levels of temperature, pressure and fuel-air mixture. A mechanical system uses either automatic or manual controls to adjust the flow rate in order to maintain the desired levels.
Another approach to furnace level control is combustion control. This is generally used in systems which use coal or gas as a fuel. Combustion control is used to ensure that the temperatures produced within the furnace do not exceed safe levels. This is achieved by monitoring the fuel-air mixture and the temperatures produced in the furnace. By adjusting the fuel-air mixture, the combustion process can be controlled to ensure that the temperatures in the furnace remain within set limits.
Furnace level control can also be achieved using electronic systems. An electronic control system can be used to precisely control the levels of temperature, pressure and fuel-air mixture within the furnace. This type of system uses sensors to monitor the levels and adjust the fuel flow rates as necessary. The sensors can be programmed to provide alerts in case of any sudden changes to the parameters being monitored.
Finally, some manufacturers use a combination of mechanical and electronic systems to control furnace levels. The combination systems make use of both mechanical and electronic components to control the fuel flow rate, temperature, pressure and fuel-air mixture in the furnace. By combining these two approaches, the manufacturer can achieve a level of precision that is not possible with just one system.
In conclusion, there are several approaches to furnace level control in gas producing furnaces. The most commonly used method is a mechanical one, however electronic and combination systems are also available. In each case, the exact approach will depend on the type of fuel being used and the desired levels of temperature, pressure and fuel-air mixture in the furnace.
