Severe dry gas application of high pressure boiler tube will collapse if the burnt gas boiler severe shortage, make the evaporation boiler superheater heating surface tubes collapse deformation even burned; reduced heating surface of steel hot or burning,; so that the expanding pipe Expansion Leakage off or loss of carrying capacity, pipe bursting; furnace wall damage, etc., if handled improperly can lead to more dire consequences. So What can cause a gas boiler water it mainly has the following aspects: operational staff negligence, strict monitoring of the water level; after boiler blowdown, not closed and not shutting the drain valve or drain valve leakage; water supply equipment or water supply? line failure, the water supply is reduced or interrupted; table water vapor, the water pipe even clogging, leakage or other causes of cock false water level; boiler waterwall convection bank, economizer tube or pipe tobacco blasting water vapor venting. Found water, the water can be called by flushing the water table, judgment is mild or severe water shortage. Step waters operation is as follows: Open water gauge, drain cocks; Close steam tap water table; water gauge Close drain cocks. At this point, if the water level in the water table appears, the boiler is a slight lack of water, or is the severe water shortage. When gas boiler slight lack of water, can first open water gauge steam cocks, restore the normal operation of the water table and reduce the fuel and air supply, reduced burning, slow to Boiler Feed, and quickly identify the cause of the boiler water shortage. When the water level in the boiler to be gradually restored to a safe level above the low line, then an increase in fuel and air, to restore normal combustion boiler.
During the manufacture, transportation and installation of the condensing boiler directly supplied by the new factory, the inner wall of the condensing boiler is concentrated with oxide or other dirt, which causes the condensing boiler to be corroded by the hot surface during its initial operation. Therefore, a series of measures should be taken to ensure the cleanliness of the condensing boiler when it is installed and ready to run. So in the process of consumer cleaning, what mistakes will be misplaced, and how to use it correctly? 1. there is no chemical analysis in the process of chemical cleaning: chemical cleaning is a very rigorous process. But if the chemical cleaning is not complete, some of the dirt has not been completely cleaned; and if the cleaning time is too long, Wash phenomenon will occur; cleaning effect is not good, secondary cleaning will waste raw materials, and delay time. The phenomenon of excessive washing will aggravate the corrosion of condensing boiler, cause the metal bearing capacity of condensing boiler to decrease, and affect the normal operation of condensing boiler. The improvement measures are: must do the chemical analysis detection in the chemical cleaning process, every ten minutes to test the acidity, the total iron ion concentration, the PH value. When the two analytical data are close, the chemical cleaning reaches the end point, neutralizing the acid solution to the neutral and then discharging.
2. no passivation after chemical cleaning: passivation process is actually a clean condensation boiler body surface and passivation agent re-reaction process. Because the control point of passivation is more strict, if the control point is not well controlled, the passivation will fail, and if the pickling is finished, only simple neutralization will be carried out, and the cleaning will end, which makes the surface of the cleaned condensing boiler easy to produce secondary floating rust. The scale-inhibiting ability of condensing boiler is reduced, which makes it easy to rust. The improvement measure is to rinse and passivate the condensing boiler after pickling. Because the passivation requirement is relatively strict, the concentration of total iron ions must be strictly controlled in the rinsing process. Rinse After finishing, the pH value should be adjusted to strong alkalinity immediately after the iron ion is detected, and the passivation agent should be added to passivate the temperature.
Since March this year, Haidong Qinghai province to implement the central issue environmental supervision feedback coal-fired application of high pressure boiler rectification work, speed up the production of green, zero emissions work processes, and improve air quality, to develop a series of coal-fired boilers on the rectification requirements of the program, as the initiative, strike out, to carry out rectification work in coal-fired boilers within the city, complete elimination of high energy consumption and serious environmental pollution of coal-fired boilers. Planned before the end of 2020, out of the new regulation since 2013 registered 10 tons of steam per hour and a total of 35 sets of coal-fired boilers. To date, 24 have been dismantled coal-fired boilers, the completion of 69% of the total demolition tasks.
In campaigns, the Haidong Market Authority established the Secretary for the head of the leading group, and achieve the "four guarantees" work. First, strengthen organizational leadership, promptly convene a special meeting arrangements, set up to director, head of the leading group, strict rectification requirements, compaction responsibility, division of labor, supervision and implementation, to ensure that the tasks, responsibilities, personnel, time to implement place; second is to strengthen the publicity and guidance, held a coordination will promote, publicize national environmental policy so that the people in charge to enhance environmental awareness, consciousness of serving the overall situation, to ensure that the main responsibility to put in place; the third is Duocuobingju full supervision of the remediation coal-fired boilers demolition work to ensure full demolition tasks to complete the rectification of high-quality, on-site in time for the use of special equipment write-off procedures to monitor and update the information platform, the rectification work will not stay dead; fourth is to strengthen the rectification pin number system and standardize accounting, according to " Qinghai province to implement the central requirements of environmental protection inspectors feedback pin number rectification work approach ", the timely development of ledger collect relevant information, to ensure that the sales numbers for the record rectification work tasks.
Up to now, the central feedback requirements Haidong included the removal of 35 planned coal-fired boilers have been demolished 24 units, of which the county mutual aid, Ledu District, safe area, Minhe County, Hualong County coal-fired boiler demolition has been completed work to complete the renovation work ahead of coal-fired boilers. Next, Haidong will continue to increase coal-fired boilers eliminated, remediation publicity work to do mass persuasion to explain, guide active community participation, active support and cooperation to carry out "ban on burning 'governance activities. Actively persuade pressure coal-fired boiler units to implement the "coal to oil", "coal to gas", phasing out coal-fired boilers high pollution, high energy consumption, encourage economic boiler unit to switch to environmentally friendly, safe and efficient biomass, natural gas, etc. clean energy.
Since the emergence of circulating fluidized bed combustion technology, circulating fluidized bed application of high pressure boilers are widely used, large-capacity circulating fluidized bed boiler has been accepted by the power generation industry in the world.There are two types of power plant boilers(Utility boilers): pulverized coal boilers and circulating fluidized bed boilers.

Low-pressure boilers are limited to 15 psig design, and are typically used for heating applications. High-pressure boilers are typically used for process loads and can have an operating pressure of 16 to more than 1,000 psig. Most steam boiler systems require saturated steam, which means the water and the steam in the vessel are at the sameGet A Quote
