4 ton condensing gas steam boiler

Check gas boiler before the preparation of cease-fire and that the flue slow cooling drum; open all manholes and hand holes in the header of the boiler body; let go of the gas within the boiler drum and water; the boiler combustion chamber, drum , flue ducts thorough cleaning; steam pipeline cleaning and removing rust and scale water; repair or replace a manhole cover; ready safelight, flashlights, test rods, tools and the like. Burner gas is an important part of the boiler, the main control system and combustion system components, the problem lies in easy control cabinet, 1. However, the normal ignition off this failure phenomenon typical cause of several tens of seconds after the self-ignition of the burner flame sensor dirty parts. The flame sensor is a photoresistor when irradiated with light of its own resistance decreases resistance value increases as a state of high impedance low impedance state when the light irradiation. Burner flame sensor controller in accordance with a resistance value to determine whether the process is continued if the combustion stop combustion flame sensor high impedance supply is immediately stopped to prevent the unburned diesel fuel reservoir. Flame sensor probe positioned within the burner duct, since the black smoke, tempering, blowing dust and other reasons that the surface thus losing readily soiling the photosensitive functionality. Check sensor probe, its surface is cleaned with a detergent or alcohol, if necessary. 2. Ignition normal exhaust smoke color but not normal diesel fuel injected into the burner is burning the mixture under stirring, when the appropriate amount of blowing water vapor and CO2 exhaust gas atomization are colorless. When there is insufficient air supply can cause incomplete combustion of diesel soot to form CO and thus give rise to the phenomenon of black smoke exhaust. However, if a strong wind inlet excessive combustion of oil mist may be blown off too late will form white smoke is discharged. Common causes of black smoke exhaust of combustion into the throttle opening is too small, white smoke into the throttle opening is reason to see through the large, two cases should be re-adjusted into the throttle. Exhaust smoke color can be observed while the side damper opening degree until near colorless in exhaust smoke color adjustment. Another reason is that black smoke exhaust poor atomization of diesel, oil mist contained in the larger droplets, can not be sufficiently mixed with the air due to a local incomplete combustion produce soot.

The use of gas 4 ton condensing steam boiler added to give businesses what benefits? National emphasis on energy conservation increased year by year, which also contributed to the gas steam boiler flourish among industry, under the premise of environmental policies and to efficiency gains, companies are willing to choose both energy-saving, and high thermal efficiency of gas-fired boiler. Gas steam boiler in addition to providing sufficient high-temperature steam, but also can reduce fuel cost by reducing the combustion load input. The use of gas steam boiler will bring any significant benefits, let's take a look. 1, the biggest benefit is the economic use of gas steam boiler can save a lot of fuel costs for businesses, you do not need to spend lots of money to purchase a large amount of coal fuel, just use good cleanliness of natural gas will be able to output enough steam; they also do not We need the fuel storage site, only need to connect to the pipeline. 2, security is well known that natural gas is a very safe and stable, non-toxic and pollution-free, good cleanliness of fuel, liquefied petroleum gas or gas leak after not deposited on the ground, and even cause accidents will burn again. Process gas steam boiler during conveying gas selected gas is the most secure, but also easily found after leakage during use and therefore is the most secure way. 3, convenient gas steam boiler in the use, operation is very convenient, so will much favored by all walks of life. Because the use of all natural gas pipeline, a sustained run without any problems. Eliminating the need to transport coal use and clean-up or stacking cinder and other tedious work. 4. Clean the reason why gas steam boiler in the market to get a high rating, but also because it is clean and not contaminated during use, and does not produce black bottom of the pot, there is no air pollution. Thus, in use, compared to other boiler is the cleanest way.

Heard so much about fast boiler made a number of achievements in the areas of clean boiler, this time my unit and quick cooperation parties, give me your company's boiler unit is in line with the requirements of our team boiler, to achieve a clean, energy-saving, environmentally friendly way of heating . Moreover, your company for the Beijing authorities have provided more office cleaning boilers, a good reputation. So, we finally reached a cooperation. --customer feedback

10 t 10 t introduce gas boiler gas boiler 4 ton condensing steam boiler dedicated configuration computer controller, all Chinese, a large screen, backlit LCD display strong, rich display, operating status of the controller and the collected pressure, water and other states may be accurately visually displayed. Complete control functions, with intelligent boiler water level control, steam pressure control, low-limit water level alarm and interlock protection, high water level alarm, ultra-high pressure steam alarm and interlock protection, automatic control functions. Very convenient to use, may be provided continuously, the timing of the two states, the timing can be divided into four time periods, the boiler regular boot, time off, without full fireman, usually only have to press the start key turned on, press the stop button to stop very easy. Features: imported burner, automatic programmed control, automatic purge blower, electronic auto-ignition, spontaneous combustion and gas, (air) to automatically adjust the proportion of oil wind, good atomization, combustion, low NOX, energy saving . 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.
