Integrated inspection-free boiler system

The invention is suitable for a direct-current coil boiler, and provides an integrated inspection-free boiler system which comprises a base plate, a direct-current coil boiler body, a steam-water separator, a deoxygenization water tank, a chemical dosing tank, a combustor, a soft water tank and a salt tank are installed on the surface of the base plate, and a boiler control cabinet is fixedly installed on the outer side face of the direct-current coil boiler body. The hot water outlet end of the direct-current coil boiler body is communicated with the steam-water separator, the nozzle end of the combustor extends into a hearth of the direct-current coil boiler body, the oil inlet end of the combustor is communicated with a fuel oil valve set, the direct-current coil boiler type is adopted, the evaporation capacity of 1 t/h can be achieved, and the fuel oil valve set is arranged at the oil inlet end of the combustor. And the smaller water volume determines the smaller length, diameter and thickness of the pipe
