Coupled with dual independent electronic water level control system to achieve ultra-low water level in the boiler, low water level automatic adjustment function, the normal water level, high water level, ensure that the boiler in a variety of unforeseen circumstances foolproof, secure home. (2) steam pressure protection ☆ pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switch, other control lines or automatic control chain protection. Common pressure controller and pressure gauge, vapor pressure overpressure alarm can cut off the burner limit is reached; the pressure controller may be single or double fire burning fire the actual operating pressure regulator. ☆ safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. (3) having a burner flame protection flame protection inlet means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged combustible residual gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. (4) self-locking power failure protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.
The boiler application requires a boiler body and many boiler fittings are required to form a complete system. The oil and gas boiler fuel system mainly provides fuel for the boiler, and has the functions of fuel receiving, storage and transportation. The combustion system mainly includes a burner and a matching valve instrument. The choice of burners is cautious, the characteristics of the fuel, and the boiler flue gas emission standards have a large impact on the choice of the burner. Oil and gas boiler flue gas systems generally require more configuration of induced draft fan, flue gas purification (dust removal, desulfurization, denitrification) equipment, chimneys and other equipment. The soda system requires many accessories to assist, including steam (hot water) equipment, water supply equipment, sewage equipment, and so on. The electric control system of ZG boiler oil and gas boiler is responsible for the safe operation of the boiler body and all auxiliary machines. Its function is to automatically detect, program control, automatic protection and automatic adjustment of the operating boiler. Instrumentation and automatic control equipment include thermometers, pressure gauges, water gauges, flow meters, negative pressure gauges, oxygen meters, automatic regulating valves, microcomputers and automatic control systems.

Multi fuel design CFB boiler Challenge
Multi-fuel CFB boilers typically burn a mixture of waste or alternate fuels along with natural gas, fuel oil,or pulverized coal.This provides an opportunity to produce steam at lower cost than a basic fossil fuel fired unit, but it also makes operations more challenging.Waste and alternate fuels vary in Btu content per volume and their supply is often not consistent. This significantly affects combustion stability and the ability to reliably meet load. More expensive fossil fuels must be used when waste and alternate fuel is not available or to make up for low Btu. Managing this without excessive cost is difficult.In addition, operating within emissions constraints may be a problem with multiple fuel streams in the mix.
