1. Pressure gauge, water level gauge, safety valve, sewage device, water supply valve, steam valve, etc., check whether the performance meets the requirements, and whether Other Valves are in good condition.
2. The automatic control device system, including the flame detector, water level, water temperature detection, alarm device and various interlocking devices, display control system and other performance status meet the requirements.
3. Whether the water supply system includes the water level of the water storage tank, the water supply temperature, and the water treatment equipment.
4. Fuel combustion system, including the fuel quantity, transmission line, combustion equipment, ignition equipment, fuel cut-off device, oil pump, etc.
5, ventilation system, including the blast, induced draft fan, adjustment door and gate opening, ventilation ducts and other conditions are good.
During the use of the boiler, the water temperature and water level probe should be cleaned regularly, and the descaling should be checked regularly; the boiling water furnace should be regularly drained from the boiling water outlet of the furnace body and the water outlet pipe and the water nozzle. Sewage must be done at least once a day.
Sewage method: Before the sewage discharge, the water level of the boiler is at a normal high water level, and the boiler pressure is carried out at 0.1-0.2MPA. Based on the principle of “diligent discharge, less discharge, and uniform discharge†(at least once a day), the short-term intermittent operation is carried out, that is, the sewage valve is opened. After that, it will be turned off, then turned off again, and repeated several times, until the water level is at a normal low water level. Remember not to empty the boiler.
Safety accessories such as pressure gauges and safety Valves of boilers should be periodically checked to ensure their reliability (the pressure gauge is at least once every six months, and the safety valve is at least once every year).
After the horizontal fuel (gas) boiler is continuously operated for 12 months, open the smoke box door to clean the dust in the furnace or the pipe, check whether the smoke box cement is falling off, and repair the falling off.
Clean and paint the rust of exposed parts such as the base at least once a year.
Stop valves are closed by screwing a rubber gasket down onto a seat in the middle of the valve. Pros only use small versions that act as shutoff valves for fixtures such as sinks and toilets and outdoor sillcocks. Flow is inefficient because of the circuitous route the fluid (water, in most cases) has to follow. It's important to orient the valve in the right direction with the arrow (cast into the side of the valve) aligned with flow direction. That way, water flows against the bottom of the rubber gasket. If the valve is put in backward, the flow will force the gasket away from the top of the valve.
