Automatic Gas Burners series APH - M(E)
Automatic Gas Burners series APH - M(E)
BASIC DESCRIPTION AND FUNCTIONS OF THE BURNER
The APH-M is a modern type of automatic gas burner designed to burn natural gas, propane butane, biogas, landfill gas and mine gas. The burner works fully automatically, and does not require any permanent control. The connected regulation of heat output and low access of air during combustion ensure highly efficient operation.
The burner is designed as a monoblock and thus the ventilator is a part of the burner’s main body. The starting cycle together with the ventilation of the combustion chamber and valve tightness control, the regulation of heat output and all safety functions are controlled (after receiving impulses from operating sensors) by MA-2 or MA-3 microprocessor automatics. The MA-2 automatics can be placed directly on the burner or on a special stand. MA-3 is produced to fit into the distributor.
The fundamental part of the automatics is a set of two one-chip microprocessors of the 8051 series, which substantially contributes to the safe operation of the whole unit by a mutual check on the algorithms of the burner’s operation. Replacement or reprogramming of the microprocessors allows the extension of the assortment of controlling algorithms of the automatics (e.g., continuous ventilation during pauses in operation, etc.). Communication of the automatics with the environment is possible manually by the operator or by a superior computer, or by remote control through RS-485 interface. Excluding basic functions, the standard automatics type is capable of the following:
- displaying information about the immediate operational state of the burner (ventilation, valve tightness control, ignition time, increase and decrease of output, etc.) by means of a two digit display and LED diodes
- displaying the reasons for the last 99 failures of the burner, which allows prompt and effective service
- displaying the ionic current level of the flame scanner
- closing the air intake line during each interrupted operation, which reduces flue gas loss caused by the flow of cold air through the consumer
The MA-3 automatics have an alpha-numeric display counter of operational hours, ventilation time which can be set, a special service regime, the possibility of a higher number of input and output signals.
APPLICATION
The burners are a suitable source of heat for overpressure and underpressure consumers, especially for steam, hot water and warm water boilers. They can also be used for other consumers with an appropriate combustion chamber which will not stress the burner with external heat (e.g. air heaters, dryers, steam generators, exchangers, industrial and bakers’ furnaces and ovens, etc.). Using the burner for special technical purposes should be under advice from the manufacturer.
