Szs structural features and gas hot water type water tube 4t boiler machine industrial of a hot gas pipe sz series of drum water boiler waterwall convection bank smoke condensate recovery chamber and the fuel combustion furnace, the flue gas convection bank into the chimney flue gas condensation recovery. Slight positive pressure of the fuel combustion in the furnace, high temperature flue gas enters the flue turn back along the furnace tube bundle, through pre-compression into a second cigarette bundle 180 enters the second bundle. After the convective heat transfer, flue gas emissions into the atmosphere. A corrugated structure with full combustion furnace, the flue gas only enhance the disturbance, increased radiation heat transfer area, increases the rigidity of the furnace, effectively reduces the expansion stress of the hearth, increase the heat transfer effect. It also promotes the combustion of fuel in the furnace, using a pre-expansion, all welded, expanded advanced technology, both to prevent corrosion of the pipes a gap, but also improves the welding strength, using threads having a high heat transfer coefficient of smoke tubes improve convective heat transfer. Reducing the exhaust gas temperature, the thermal efficiency of the boiler increase. Features szs type gas hot water boiler 1, reasonable structure and layout of the boiler, the boiler can be assembled 10 tons shipped. 2, a large number of heating zones. Boiler heating area, an output; 3, advanced PLC control system, clear, practical. 4 ,. using advanced imported burner, fuel burn rate, reduce the cost of enterprise economy. 5, the structural design of the boiler is reasonable, low requirements for the construction of the boiler room, boiler selected according to the actual conditions, reduce procurement costs.
February 13, 2019, a food processing plant in Heilongjiang province, after the Spring Festival to resume production process, 4t boiler machine industrial explosion accident occurred, killing two people were killed, to the masses lives and property of people come at a cost, resulting in adverse social impact .
To reduce boiler accident, maintain social stability and security personnel, Suihua City Market Authority to act quickly, on February 15 Kusakabe issued an emergency notice to deploy to carry out safety hazards investigation boilers within the city, the focus of the investigation after the Spring Festival recovery boiler operation baths and other crowded places in boilers, boiler timely elimination of security risks in the management and operation aspects of existence.
As of now, law enforcement officers deployed 116 times, check unit 52, checks the boiler 64 for five in the boiler there are security risks of Special Equipment Safety Supervision issued a letter of instruction, ordered to stop using, be put into use after the rectification qualified.
Talk about safety rules steam 4t boiler machine industrial steam boiler is a gas often in special equipment working under high temperature conditions, improper operation will have a risk of explosion. To ensure their safety, economic operation, specially formulated the following procedure: First, the duty must strictly observe labor discipline, not AWOL, not doing things unrelated to the unit during operation, and strictly enforce the rules must not illegal operation, and strictly drunk and sick to work. Second, keep an eye on the water level and pressure changes, so that combustion stability, stable water level, steam pressure stable. Is strictly prohibited water, full of water and overpressure run accident occurs. Once the severe water shortage in the boiler found that the boiler water is strictly prohibited! Third, the periodic flushing water pressure gauges, which remains clean and bright, easy to observe. Automatic water level control, over-pressure protection device and alarm device chain, must always be sensitive and reliable in the state, found that the problem should be repaired in time. Fourth, the valve should have regular manual test (once a month, a day shift within a month, the operation should gently pull handle with care) and vapor dynamic test (per quarter) for a day shift) to maintain its sensitive and reliable. V. earnestly implement sewage system and operating requirements, to reduce the level of emissions per 25 ~ 30mm is appropriate, should run at a high pressure, low load. Sixth, the duty should be carried out inspection tours in the boiler, in order to grasp soon safety accessories and a boiler ancillary equipment (such as economizers, pumps, motors, valves, etc.) can not be found safe operation of boiler feed water to the boiler or other threatening when running situation, should immediately stop running. Seven, water quality testing staff often get in contact, water quality control, water quality strict implementation of national industry standards, strengthen water quality management, to avoid the knot raw scale and corrosion inside the drum. Eight, careful operation, outside the fireman on duty personnel at any other person shall tamper with the console press the knob in the boiler and valves, instrumentation, etc., fill out the log boiler.
Note that when using a steam 4t boiler machine industrial steam boiler Di operational considerations when using should be very cautious Di, because the slightest mistake will bring harm to the person, so it should be more cautious when operating, steam boilers Di understand instructions, clear operation in Di precautions. Editor's based on years of experience, we need to pay attention to when the steam boiler Di operational considerations summarized as follows: First, before the operation the boiler must be familiar with the use of the manual, simply to protect the safety of the operator and the normal use of the device Di, before starting Check the power, voltage and water whether the normal operation of the water supply valve closed drain valve open, check the pump stuck, stuck if the water pump cover remove the fan, scroll to the motor shaft flexible state to boot, so as not to turn off the power to inspect boilers live work or replacement of parts dangerous. Secondly, the electronic control box, pump motors and other parts should avoid damp water to prevent burning boiler should pay attention to keep clean, according to the boiler water quality requirements, be sure to install a water softener in the use of equipment, because they do not use a water softener can cause Boiler scale, will result in burst pipes shorten the life of the boiler when severe. Finally, if there is no demarcation in accordance with the use of water treatment equipment caused by the above situations are not covered under the warranty, please pay attention when using sewage. To discharge once a day and with a discharge pressure of 0.1MPa-0.15MPa, can prevent clogging pipes, sewage pipes should be properly connected to prevent burns, the flexibility of the safety valve should overhaul, at least once a month to quickly pull the lever to check the safety valve flexibility it off and back seats, the safety valve should be regularly every year to the local technical supervision for verification.
