8t Natural Gas steam boiler Supplier

Oil-fired boiler safety instructions oil-fired boiler is one of many hot water boiler to one of how to prevent boiler fuel boiler appears to be abnormal use it? First, to ensure the normal operation of the fuel in the boiler feed water quality and quality of qualified soda, to reduce the water wall tube fouling and corrosion, strengthen supervision and boiler water boiler water when found unqualified, should increase the number of times a given row; while the flue gas flow rate control , especially when the flue gas velocity in the corridor, during installation and servicing, should minimize the distance between the wall and the superheater tubes, while the distance between the tubes to uniformly as possible. second, the fuel boost heating boiler carried out in strict accordance with procedures, control the speed boost. were lower header sewage water wall work required to build the water cycle as soon as possible, promptly switched the gun to ensure uniform heating surface is heated to eliminate half of combustion, eliminating thermal excursions. third, do a good job adjusting fuel combustion boiler, the flame deflection preventing, controlling coal fineness noted that, with a reasonable air to prevent coking, reduces thermal excursions, to prevent the tail reburning fuel boiler; boiler steam parameters be closely monitored, and the main indicators of the amount of water evaporation and the like, to prevent pressure Release, full of water, water accident. fourth, strengthening sootblower sootblower and management, serious fouling preventing heating surface, when there is found furnace coking phenomenon, should be increased blowing Gray times, ensuring good water wall heat sink; overheating problem of the presence of long-term heating surface, installation of thermal supervision controlling temperature measuring points; expansion to ensure accurate indication means using oil-fired boiler units must be fully taken into account the safety problems. in the inspection process must be meticulous in place. to ensure the personal safety of the unit.

Fuel gas control step and the blowing process air volume of the total fuel gas 8t steam boiler supplier steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.

Boiler multiple protection: (1) the integration of boiler water level to protect water level and boiler design, the appearance of more compact appearance, accurately show the actual water level in the boiler body function. 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.

April 17, Nantong, Jiangsu Province, the municipal government issued the "Nantong City 2019 air pollution control program of work" ( "Program"). "Plan" is mentioned: Nantong City, 153 Taiwan boiler regulation reform, which involves natural gas boilers, biomass boilers, coal-fired boilers; renovation project and will continue to implement ultra-low emission coal-fired units, a total of six thermal power companies more than 10 sets of 75 tons of steam / hour implementation of ultra-low emission coal-fired boilers.
