Under normal circumstances, when the boiler steam pressure reaches the set value, the burner combustion is automatically stopped, when the steam pressure is below the set value, the burner is automatically started. When the abnormal phenomenon of the fuel, air intake, fault lights, the output sequencer will immediately stop the fuel, burner shut down automatically. Advantages 1,10 tons of gas steam boiler furnace design and manufacture Three-pass boiler, wet back, eccentric furnace, asymmetric structures, waveform furnace, so that the flame produced a strong disturbance, and increased radiation heating surface, increased strength heat transfer coefficient, and can effectively prevent metal thermal expansion and contraction resulting in reduced life of the device. 2, the whole high degree of automation, security improved. Run fully automated process, with automatic replenishment, water shortage, overpressure, automatic power off and alarm, leakage protection and other security systems. 3, the whole body as glass wool type insulation, light weight, good thermal insulation effect, less heat loss; protection system: (1) protect the boiler water level indicator and integrated design of the boiler, the appearance of a more compact appearance, function accurately display the boiler The actual body of water. 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.

Gas boiler szs 1 emergency shutdown procedures, if necessary emergency shutdown generally, when the boiler encounters one of the following, operation should be stopped in case of emergency; (1) allow the boiler steam pressure exceeds a safe pressure, fueling is stopped strengthen water supply, measures the wind pressure continues to rise. (2) boiler severe water shortages. Water meter can not see the water level. After being called water, the water level of sight. (3) When the severe water boilers, boiler water level is higher than the highest water level is visible, but the emission level not yet seen. (4) increase in boiler water, take other measures, the water level will continue to decline. (5) water supply device is turned off, standby equipment. (6) all water level gauge or invalid. (7) All the safety valve all the failures. (8) All all-off failure drain valve. (9) causing damage to the boiler pressure element (e.g., boiler tubes, etc.), or endanger the safety of the device. (10) boiler is a serious threat to other events and safety equipment. 2, natural gas boiler operation method szs immediate emergency stop operation of the controller, the boiler is off, closing the front of the boiler gas valve to stop the gas supply. The condensation type fired steam boiler competent completely separated, opening the exhaust air valve or safety valve steam pressure. Due to lack of water, the boiler is not allowed into the boiler, the steam is not discharged to reduce pressure. No shortage of water, cold water can drain down alternate method, the water level remains complete accident should immediately stop the water supply, water reducing combustion (fire artificially changed into a small fire), play an open valve while opening the main steam pipe and the drain valve cylinder to prevent the steam to carry large amounts of water, water. In the shutdown process, the cooling rate of the furnace should not be too fast to avoid flue compression member and the expander is damaged suddenly cooled. 3, emergency shutdown processing method szs natural gas boiler in the case of emergency shutdown, due to the nature of the accident, the following may take a different approach: (1) rapid flame treatment emergency shutdown, the burner first station, and closing the valve flame gas supply is stopped after the cut valve, to maintain the water level is normal. (2) rapidly cooling the furnace or water if there is no water leakage during an emergency stop, the cooling time can be shortened to the boiler water and sanitation and reduce the pressure. When the boiler water temperature down to 80 degrees Celsius, boiler water can be discharged. If the boiler severe water shortages, the boiler can not cool quickly in the event of an outage. Non-water to the furnace, or explode. accident. (B) natural gas boiler shutdown SZS normal shutdown (complete shutdown, shutdown maintenance) procedures which can be used when needed repair or stop steam boiler. 1. If one of these faults, the leaders agreed, the boiler can be temporarily closed repair: bilge faucets, riveted joints leak, damaged tubes, the waterwall tubes, the heating tube, the flue gas contacts the drum, the head, off pipe insulation, water supply system, combustion system, a serious fail-safe accessories, in need of repair. 2, a temporary repair (or normal shutdown) the method of operation in order to stop the burner, for closing the valve. Boiler feed water to 2cm above the normal water level, to stop water supply, reduce the pressure. 3. Turn the main steam valve, open the traps, and steam boiler operation, reliable water separator. 4, boiler feed water close electric valve and manual valve, boiler feedwater reliable cutting. When the steam pressure drops to zero, the water can be supplied and discharged alternately, so that water is gradually cooled furnace, when the temperature drops to 50 degrees Celsius (or hand potshell touch feeling hot pan head), can be completely discharging furnace boiler water water . Before water, open the air valve on the boiler or lift safety valve. At this point, you can enter the furnace for inspection and repair. Cooling the furnace must be kept slow, non-violent cooling and damage to the boiler, the boiler can be stopped from the repair into the furnace, the cooling time is generally less than 24 hours. Close the furnace over 24 hours, shut off the gas supply valve at the regulator, and open the gas conduit pipe is responsible, in the exhaust gas pipeline.

In the last meeting on April 16, the hard efforts of audits and company officials of president Mr. Lu Haigang couplet review group to pay thanked rigorous review and couplets group work style, professional skills to express my sincere admiration.

Scale thermal conductivity gas condensation type fired steam boiler is only one out of steel gas steam boiler efficient and environmentally friendly use of non-corrosive cleaning agent in the cleaning process of cleaning the boiler. This will cause the device to the metal tube is exposed to the primary colors, and reduce the effects of biological fouling algae sludge. After ignition gas steam boiler, furnace and to observe the temperature of main steam. Main steam pressure rises, the boiler flue gas temperature significantly higher ignition. If the temperature does not rise, you should immediately to the scene to check the oil gun fire. Scale thermal conductivity gas steam boiler is only one-tenth of steel. When it is scale on the heated surface, which will hinder the heat transfer effect. To maintain the boiler output constant during use, the need to increase the temperature of the combustion side. Gas-fired steam boiler furnace exit temperature rise, increasing the loss of gas steam boiler scale on the device can effectively reduce the water wall heat transfer, the temperature of the water is likely to lead to an increase in the wall, resulting in a wall of water burst. When the gas steam boiler, the furnace will be a series of chemical and physical reactions. During use, it will be effective to form a dense and hard scale on the heating surface, which will lead directly to heat exchange. Due to the scale and efficiency while reducing corrosion can lead to heat gas boiler absorption.
