Food processing plants most use coal-fired boilers to provide steam needed for production. For a long time, coal-fired boiler boiler industry occupies 90% utilization, the coal price is not high, suitable for economic development is relatively backward areas, and less demanding on the coal boiler, use low heat, low-quality large ash coal, by the boiler industry favorite. But with coal combustion caused by sulfur dioxide, hydrogen sulfide, nitric oxide, dust and other harmful substances, causing serious air pollution, fog and haze has cropped up, China's increasingly stringent air pollution, coal-fired boilers faces comprehensive reform issue or banned.
Oil-fired boiler that is why oil-fired boiler smoke black smoke to the situation occasionally occur, this time do not worry too seriously looking for the cause, then you can solve. First, poor fuel atomization Second, oil gun malfunction Third, injector coking Fourth, the lack of wind. five, with winds inappropriate, harmful oil mist and wind ratio, resulting in local hypoxia and produce pyrolysis. Sixth, the occurrence of post-combustion flue seven, the boiler starts, the beginning of the furnace temperature is too low, air temperature is too low. how to solve the above circumstances the above situation? A boiler fuel, ignition oil gun before checking to ensure that two normal use, remove coked at the nozzle, three, four enhanced oil atomization quality, to ensure that the oil burner gun into the correct position. Five, to ensure the operation of the boiler oil, oil pressure and fuel back to the right viscosity index VI, timely and appropriate manner into the root of the wind, adjusting the primary and secondary air damper, oil mist mixed with air properly to prevent local hypoxia. seven, to maximize the wind mild furnace temperature above ground can be a good thing to solve exclude oil-fired boiler smoke to the situation.
How boiler superheater tube system is damaged do? Damage phenomenon is divided into: a noise close to (1) Superheater. (2) normal steam flow is not less than the water flow. (3) the combustion chamber or the negative pressure Modifier abnormal shaking, etc. Manhole by a severe steam spraying or flame and smoke outwardly. (4) damage to the superheater flue gas temperature is reduced. (5) superheated steam temperature changes. Process: the tube is damaged after inspection is really a superheater, must immediately return, repair shutdown. Only to be stopped after the draft fan furnace steam disappeared, in order to prevent accidents to expand and extend the processing time. When the damage is not serious superheater tubes, the monitor returns immediately, long value, Director of Operations, allowed to run for a short time. The enlarged portion and deterioration when damage value of the long shutdown request, according to emergency shutdown process.
Tai Chi, Jiaozuo City, Jiaozuo City Sports Center is one of important sports infrastructure, a total area of 11.73 hectares, held several international events. With strict management in Henan Province for air emissions of pollutants, Jiaozuo City, also launched the governance of coal-fired boilers, thermal power and other equipment. Jiaozuo Sports Center actively cooperate with municipal workers, took the lead from coal to gas activities, the serious pollution of the original extent of coal-fired boilers to replace gas boilers. Gas boiler cleaning binding understanding of the market, to achieve cooperation with the finalization fast boiler by providing a fast side 2.8MW integrally condensing gas hot low pressure water boiler for central heating (WNS2.8-1.0 / 95/70-YQ), it is used to Sports Center provides heating and hot water.
Feeding water to the central heating system when water is low. Providing a place for the hot water to go when your system has overheated. Pump. A pumps job is to push hot water around your heating system. Without the pump the water will just sit still in the pipes. The location of a pump is usually placed inside your boiler or in your airingLearn More
Releasing water from your central heating system can lead to a pressure loss. Fortunately, there is a way you can increase pressure in your boiler system, without having to call out an engineer. Leak in heating system. The other reason for low boiler pressure is that there may be a leak somewhere in your central heating system.Learn More
Jul 09, 2019 · Low boiler pressure. Combi and system boilers require a pressure of 1 1.5 bar when cold in order to work. If the pressure is lower than this, the boiler wont work and you wont have any hot water or central heating. Low boiler pressure is one of the most common boiler problems and it can have many possible causes.Learn More
What the hell is boiler pressure and why do you need boiler pressure? Boiler pressure is simply the balance of water and air within your boilers sealed system.. In order to function correctly, your boiler needs a particular balance of water and air to ensure the pressure in the system is adequate for when water is demanded from the boiler essentially when you switch on your heating or hotLearn More
Ever since, every 2 or 3 days the water pump alert flashes and the boiler stops working. To reset I generally have to unplug the boiler for a few seconds and plug it back in, which instantly resets it. According to the manual this refers to: Fault on pump or low system pressureLearn More
How could mains water pressure affect my combi boiler? For all cold-mains-fed combi boilers, it is important to ensure (before/at the time of installation) that the water main is large enough to deliver adequate water to the boiler whilst other cold outlets are in use (eg flushing toilets, washing machine filling or cold taps being run).Learn More
Oct 26, 2019 · A boiler refers to a system in a building that heats water into steam to produce hot water or central heat. While it is more likely that you will encounter problems with low pressure, it is not uncommon to run into issues with highLearn More
Solutions For Boilers With Low Pressure Problems. Many modern boilers are installed as part of a sealed central heating system, the water pressure is deliberately kept high so it can be pumped to all the radiators in the home.Learn More
Boiler pressure too low can be a scary thing to deal with. After all, how does it actually work inside that big, white boiler? The designs of combi boiler systems are made to be economical, functional and reliable.Learn More
The position set when the boiler was installed is sometimes shown by a red indicator needle. On most digital gauges, youll see a flashing pressure reading, if theres a low (or high) pressure warning. If your boiler pressure reads less than 1 bar, its possible that you might have lost water from the system, which needs to be replaced.Learn More
Correct water pressure is essential for the efficient functioning of your boiler and heating system. If the boiler pressure drops too low then your boiler may no longer function. What causes low boiler pressure? Commonly leaks may occur on the many joints along the pipework or inside the boiler.Learn More
Oct 22, 2018 · OK, it's indeed the PRV: When the boiler fires up and starts burning gas, a few table-spoons of water spurts out of the pipe, but there is no long term dripping as the water is driven around the central heating system. Secondly, the pressure rises by half a bar to 1.5 bars; so it would seem the pressure vessel also needs to be pressured.Learn More
Nov 10, 2016 · Hi, our gas boiler was moved when we had an extension built and the gas supply pipe is now at least 20m from the meter with many bends. It's time to replace the boiler but my plumber says the gas pressure at the boiler is way too low (I think he said 13?) and advises sorting this out before getting a new boiler, which I want to do.Learn More
