cng thermal oil heater feed plant water tube boilers
WNS series oil and gas cng thermal heater feed plant water tube boilerss are fire-tube, horizontal type boilers with natural circulation of boiler water for the combustion of liquid and gaseous fuels. We can supply boiler body, the respective fittings, boiler valves and instruments and gauges. Upon the client’s request, the boiler can be equipped with a feed pump and feed water control.
In early November, Luyi County, Henan Province Quality Supervision Bureau organized a safety inspection activities on the cng thermal heater feed plant water tube boilers in the area, ensure the safe use within the jurisdiction of the boiler in winter.
The main focus of inspection units use boilers to see through the following points:
First, the use of registration, maintenance, periodic testing situation.
Second, the establishment and implementation of the system and the rescue plan.
Third, if the boiler worker certificates.
Fourth, the operation of the boiler water treatment facilities.
To date, Luyi County Quality Supervision Bureau has complete supervision and inspection work on 11 units in the boiler, the inspection found problems and risks, monitor the instruction issued according to the law, clearly boiler rectification matter and time.
In theory, the cng thermal heater feed plant water tube boilers fuel consumption under ideal operating conditions = boiler output / fuel calorific value / boiler thermal efficiency.
1. Boiler output refers to boiler power. Steam boilers generally refer to evaporation (t/h), and hot water boilers are thermal power (MW). So far, ZG boiler has been able to produce nine systems and more than 200 products. The wns series horizontal oil and gas boilers produced by ZG boiler have a capacity range of 1-20tph.
2. Boiler thermal efficiency refers to the percentage of effective heat and heat input to the boiler at the same time. Like the wns series of fire tube oil and gas boilers produced by ZG boiler, the thermal efficiency is high, up to 98%.
Maintenance of the cng thermal heater feed plant water tube boilers and burner maintenance 1, boiler maintenance and deactivation of backup boiler, should take anti-corrosion measures. 1) maintenance Calorimetry: maintaining the furnace pressure 0.05 ~ 0.09MPa, the water temperature of about 100 deg.] C, to prevent air entering the boiler, this method is suitable within a boiler shutdown week. 2) Wet maintenance: After disabling the boiler, put the water came out, the interior completely remove the dirt and cleaned, refilled been handled well demineralized water, softened water filled boiler. Then adding alkali to the boiler, when added with sodium hydroxide aqueous 5 kg per ton to 6 kg, per ton of sodium carbonate was added if the water 18 kg to 20 kg per ton of water when trisodium phosphate is added 10 kg to 12 kg, maintaining the PH value above 10. The furnace was then heated to 100 deg.] C water, the safety valve is opened, air is discharged in the furnace, and then closed. During maintenance should always check and found that leak that is to be cleared. When the boiler is enabled, it should be drained alkaline solution, and rinse with water, especially when the plot scale boiler must deactivate more clean, because the scale can be soaked in lye and fall off, clog pipes. The method is suitable for longer-term disabled boiler. 2, the burner maintenance: 1) cleaning and maintenance of the burner: Open the combustion head, with a cleaning wipe member or combustion gas, a flame detector wipe with a clean soft cloth, carefully clean the duct and the fan wheel. 2) maintenance of the oil (gas) passage system: Remove fuel (gas) pipeline, cleaning fuel (gas) each filter and nozzle, the drain valve is opened daily oil tank, with exclusion of moisture and impurities in the waste oil. 3) maintenance circuitry: Check whether each wiring is connected firmly assembly is intact and the like.
