The basic function of the ignition system is based on the work of the engine order of timely strong high pressure to the engine spark. Ignition system features embodied in the ignition spark ignition timing and intensity of production. To achieve direct current can generate enough strength into the high-voltage spark, and only through the use of transformer secondary coil and primary coil to produce a larger ratio of high voltage.
Fuel combustion boiler start and load electric power generation constitutes an important part of the development of new technology to reduce cost of electricity is an imminent large-scale thermal power generation market, in recent years as the world crude oil prices and fierce competition in the domestic power plant, the pursuit of save fuel combustion power plant boiler ignition and increasing demands, no oil burning ignition system is necessary.
In this thesis, the plasma ignition control system network, control system hardware configuration, plasma generator control logic and plasma ignition control logic, control system interfaces with the DCS system. Also made a number of the problems in operation, and Solutions. This design of the boiler ignition control system, so that staff do not need to operate the equipment in the field so, only in the control room remote control system operation and automatically monitor the situation.
