How to identify whether the toxic chemical plant boiler emission sources on how to identify whether the toxic chemical plant boiler emission sources? Now, the chemical inside the boiler or the production of major productivity. But there is a time of some chemical plants for production of boilers, flue gas emissions place are smoke smoke. Which is the most common white smoke tobacco, and there are a lot of people will find that the more obvious the more cold weather white smoke, which is why in the end, saw the boiler flue gas chemical plant will be white coming out. In fact, most white column of smoke, especially in cold weather to see, and water vapor is condensed water droplets nothing. Boiler feed water tank is equipped with a chimney, only water vapor and air emissions. Water is one of the important by-product of combustion, so the chimney of coal, oil and natural gas boilers have water vapor. To reach reduce dust pollution emission regulations, companies will discharge terminal apparatus water filtration apparatus into the exhaust gas boiler water filtration, all the inside of the dust filtered off, and then discharged to the atmosphere. Hyperthermia with dust filter, the exhaust gas is also absorbed by water to form water vapor is discharged from the chimney, the cold white smoke that we see a. In chemical plants, always able to see a kind of braving the plume of flame, burning in it day and night, in fact, this is not a column of smoke, its name is called safe torch. Chemical plant in the production process, many of flammable and explosive gases can occur, many of which are harmful. They are large heavy than air, if released into the atmosphere, by extension, be deposited on the ground and reaches very high concentrations, which will form a serious environmental pollution and damage to human health, should encounter fire, the fire will be formed, and the blasting . In order to prevent the onset of these risks, people will set them up and burn to prevent future trouble. There is also a mistaken chimney built, in fact, they are cooling towers, water vapor is discharged from the sterilization algae and some trace of drugs. Cooling towers is cold and hot water and steam generation using the air flow after the touch, the steam reaches the transpiration transpiration remove heat dissipation, convective heat transfer principle of thermal radiation and dissipate heat like occurs in industrial refrigeration and air conditioning, or to decrease the water temperature transpiration cooling means to ensure the normal operation of the system, it is above the water vapor.
Gas introduced gas steam boiler steam boiler stop sign Profile: natural gas steam boiler is a steam boiler gas, natural gas steam boiler with natural gas as fuel, the combustion in the furnace heat put out by heating the pot water, and allowed to vaporized into steam energy conversion device. Water pan (drum) is continuously released from the combustion of a gaseous fuel energy to heat the furnace temperature is increased and produce steam under pressure. Since the boiling point of water increases with increased pressure, the pot is sealed, the expansion of water vapor generated inside the pressure limited thermodynamic formed, strictly speaking, the steam boiler is heated in water at constant pressure saturated steam drum regasification water formed, is widely used as an energy source. Protection device: (1) protect the boiler water a boiler water level gauge plate supporting one to two, should always be compared with each other, inconsistent findings indicate that shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. (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 switches, other control lines or automatic control chain protection. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. 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. Editing boiler ignition procedures: 1. Check operation and (or) shift recording. 2, inspection, examination boiler, external. 3, check the main safety accessories. Safety valve, water gauge, pressure gauge, to be tight, reliable and sensitive. 4, check the water treatment equipment. 5, inspection equipment and soda water supply system pipe. Adjust the valves as required to start. 6. Check the oil supply equipment. After the above inspection qualified, you can start the boiler. Note: The boiler is a high-temperature, high-pressure thermal equipment, is one of special equipment, widely used in government agencies, public companies and all walks of life, it is dangerous and special equipment. Event of an accident involving public safety, it will cause huge losses to the state and people's lives and property. For public safety, people's lives and property safety, according to the State Council, "Regulations on Safety Supervision of Special Equipment", the boiler should use full attention the following matters: 1, should be accompanied by safety technical specifications of the factory boiler design documents, product quality certification, safety and the use and maintenance instructions, supervision and inspection certificate (safety supervision, inspection and performance certificate). 2, boiler installation, maintenance, alteration. Engaged in the installation of the boiler, maintenance, renovation of the unit shall obtain special equipment installation and maintenance certificates issued by the Provincial Quality and Technical Supervision, before engaging in the boiler installation, maintenance, alteration. Construction unit before construction will be prepared for installation, maintenance, alteration in writing inform the special equipment safety supervision and management department of the municipality or district, and will start informing sent to the local county level Quality and Technical Supervision for the record, told immediately after construction. 3, inspection of boiler installation, maintenance, transformation. After construction, the construction unit To State Quality and Technical Supervision of Special Equipment Inspection and hydrostatic testing of the boiler installation supervisory inspection declaration. After passing by the State Quality and Technical Supervision, State Special Equipment Inspection, County of Quality and Technical Supervision involved in overall acceptance. 4, registration boiler. After the boiler inspection, the use of units must be in accordance with the "special equipment registration and use of management rules", fill "boiler (census) Registration Form", the State Quality and Technical Supervision to register and obtain a "registration certificate to use special equipment safety . " 5, operation of the boiler. Boiler operation must be performed by trained and qualified to obtain "special equipment operator certificate" certified personnel to operate, must strictly abide by the rules and eight systems, six record. 6, check the boiler. Periodic inspection of boiler once a year, not be used without safety periodic inspection of boilers. Safety accessories safety valve of the boiler regular inspection once a year, pressure gauge biannually verified, may not be used without the periodic inspection of the safety accessories. 7, non-pressure boilers will be installed for the boiler pressure. Do not use water level gauge, safety valve, pressure gauge three safety accessories insufficiency boiler.
