mechanical natural gas steam fire tube boiler
Hot water mechanical steam fire tube boiler which is not equipped with no impact can cause demineralizer 1, the waste fuel boiler fouling occurs, resulting in poor heat transfer performance of heating surface, so that heat generated by the combustion of the fuel can not be timely delivered to the boiler water, but a large amount of heat is smoke away, resulting in exhaust gas temperature is too high, if the exhaust gas loss increases the thermal efficiency of the boiler will be reduced. In order to maintain the nominal parameters of the boiler, fuel must be increased, thereby wasting fuel. About 1 millimeter scale waste fuel ten percent. 2, the heat receiving surface is damaged due to deterioration of the heat transfer performance, fuel combustion heat is not quickly transmitted to the boiler water, resulting in the furnace and the flue gas temperature. Thus, the temperature difference on both sides of the heating surface increases, the metal wall temperature, a decrease in strength. Under pressure pot, bags and even blasting will occur. 3. Reduce heat boiler output due to the deterioration of the performance of boilers, need to consume more fuel to reach the nominal rate of evaporation. However, with the increase in the scale thickness, the volume of the furnace becomes large, the fuel consumption is limited. Therefore, it is possible to reduce the output of the boiler. 4, the corrosion damage to the metal: oxygen in the water, acid, base materials will corrode the metal surface of the boiler, it is thinned, recess or perforation, thus reducing the power of the boiler, seriously affect the safe operation of the boiler. 5, in addition to improper operation Priming outside, when the boiler water contains more sodium chloride, sodium phosphate, and silicides oil, boiling or evaporation process boiler water, boiler water occurs when soap and organic base when Teng because soda will produce compost. Foam liquid surface, formed soda pool. No softening, easily scalable. Due to the continuous evaporation steam, boiler of calcium, magnesium, high impurity concentration is 30-50 times that of natural water, fouling rate beyond our imagination, only six months to a year, from 1-2 mm.
What are the precautions in the loading and installation of gas-fired steam mechanical steam fire tube boilers?
Gas-fired steam boilers are a very wide range of special equipments, widely used in food, chemical, paper, textile, construction and other industries. In the process of loading and installing a gas steam boiler, some problems must be paid attention, otherwise it may cause a certain degree of economic loss.
1. Pay attention to the following matters during the loading and unloading and handling of gas-fired boilers: the lifting capacity of the lifting equipment should match the weight of the lifting boiler. The lifting lug on the boiler with the lifting lugs that cannot be used for lifting can not be used for lifting. The length of the steel cord should be reasonably selected to avoid the scratching of the furnace due to the improper length of the steel cord. The boiler must be protected from any damage during handling and handling.
2. Reserves for maintenance space When installing boilers, ensure that there is sufficient maintenance space around the boiler.
3. Setting and precautions for the base and base of the gas steam boiler The boiler body must be installed on the basis of 100-150mm above the floor of the boiler room. It must be confirmed with the technical personnel of the boiler manufacturing company in advance and constructed according to the basic drawings. The anchor bolts must be reserved on the foundation. The foundation shall be capable of withstanding the maximum weight of the boiler and the amount of water it holds. When installing the base, you must first position it. After positioning, adjust to the same length of the two diagonals of the base, and then tighten all the fixing bolts. The installation of the base is carried out with reference to the reference line.
4, general precautions Be careful not to tilt and impact the boiler and accessories too much. No combustibles can be placed around the boiler. Do not use oil and water to smother the boiler. The boiler should normally be installed in a separate boiler room. The new gas-fired boiler room should not be connected to the house. The boiler room shall not be connected to Class A, Class B and Category C fire hazard rooms using flammable liquids. If connected to other production plants, the application firewall is separated.
5. The fire resistance grade and fire protection requirements of the boiler house building shall comply with the requirements of the Code for Fire Protection of Building Design and the Code for Fire Protection Design of High-rise Civil Buildings. The ground of the gas steam boiler room should be flat, non-flammable, no water accumulation, and the foundation load should meet the requirements. The power supply voltage of the gas steam boiler room should be stable to avoid causing the electrical components to burn out. If the voltage is unstable, it is recommended to install a voltage regulator. Ventilation equipment should be installed in the boiler room, and the boiler should be kept at room temperature below 50 °.
Beijing SL Pharmaceutical Co., Ltd. as China's key high-tech enterprises, has great influence in the pharmaceutical industry. In early 2017, two-Heron relevant person in charge to get in touch fast mechanical steam fire tube boiler, double-Heron Pharmaceutical according to demand, our company to provide a 1-ton split steam condensing steam boiler, and is responsible for subsequent transportation, installation and commissioning work .
Successful ignition of fuel steam mechanical steam fire tube boiler can not run, because of those common oil gas powered steam boiler applications, all of you should ignite the fuel steam boiler in the application process, no way ignition is also the most common problems. Fuel steam boiler in the application process, most likely resulting in no way ignition, resulting in fuel steam boiler can not run normally, small series to introduce you to a steam boiler does not ignite the fuel to run those common reason. Fuel steam boiler can not run common ignition of those reasons: First, the ignition problems: pulse ignition and control systems such as the one of which has caused the problem, the fuel steam boiler can not start. Second, the battery thing: to be very important to see if the battery is a battery in the end is not too aging. The charge is not standard, the same can not let steam boiler fuel ignition. Third, the water pressure thing: at the inlet steam boiler fuel filters block the formation of water can not flow normally through the clean up clean ok. Fourth, the pulse valve problems: If the boiler ignited fuel vapors to ignite division saw sound, no pulse valve "despair" squeak, probably for the pulse valve is damaged or degraded, pulse valve degeneration, will not manipulate, the beginning of the ignition operation when closing a flow will hit a fire, but the fire immediately and confinement; pulse valve before confirm whether there is a problem to confirm whether normal ignition actuating member, if the fault can not pull the valve actuating pulse. V. ignite feelings needles or needle thing: fuel steam boiler ignited hand shift. You can change or correct the ignition pin arrangement; if feelings of degradation promise things, as long as the feeling wiped clean arranged on it. Six, usually no way to exhaust smoke tube. Smoke tube steam boiler with a fuel block, clean breathing tube blockers smoke tube is too long, the configuration is not correct. Referring may be configured to inform two coaxial cigarette heater tube. VII vapor setter joint problems: fuel steam boilers, water vapor degradation intimal flap valve or joint damage, not the weak control push button switch; weak bad control switch button.
