Fang fast production of gas no steam hot water boiler system, in order to highlight the efficient, durable, safe and reliable, simple operation and other advantages, achieved excellent results in the field cleaning boilers, harvest a large number of customers and recognition.
To stop running after the boiler flameout, why fans need to continue ventilation 5min? Since the flame shutdown process, since the furnace temperature is lowered, the combustion unstable, so that incomplete combustion of fuel increases, the fuel remaining in the furnace and the flue waste heat of the furnace under heating, then combustion will produce a direct threat to the safety of boiler equipment. So turn off the boiler, ventilation fans continue for some time to take away the fuel in the furnace, but ventilation time not too long, otherwise due to the large amount of cold air directly into the furnace, make the furnace, flues and various heating surface is rapidly cooled contraction, resulting in damage. Therefore, the boiler flame, the ventilation fans continue 5min stopped, and then close the shutter smoke duct, so that the furnace and the flue is in the closed state, and also continues to monitor the flue gas temperature to prevent the pump do not re-combustibles combustion.

How to solve the fouling problem of Gas-fired BoilerIt is well known that gas-fired boilers are energy-saving and emission-reducing products, so they are loved by many customers, but in use because of the water quality problems, the boiler will form scale, then how is the scale formed? What should we do about it? Formation of boiler scale: after a long period of operation, the boiler inevitably has the problem of scale and corrosion. The main reason for the formation of boiler scale is that there are hardness components in the feed water, and after high temperature and high pressure, the boiler is continuously evaporated and concentrated after high temperature and high pressure. A series of physical and chemical reactions take place in the furnace, eventually forming a hard, dense scale on the heated surface. So the harm to the boiler can't be ignored. The heat transfer effect is reduced and the corrosion is caused by the corrosion under scale, which results in the decrease of heat absorption in the boiler water wall furnace, the increase of boiler outlet temperature, and the increase of boiler loss. After scaling in the water wall, the heat transfer effect is reduced, which may lead to the increase of the temperature in the wall of the water wall and the explosion of the tube in the water wall, which affects the safe operation of the boiler. Scale is boiler; The first is the main cause of boiler accidents, and its harm is mainly manifested in the waste of a large amount of fuel: because the thermal conductivity of the scale is only a fraction of that of steel, the heat transfer will be blocked after scaling on the heated surface. In order to maintain a certain output of the boiler, it is necessary to raise the temperature on the side of the fire, so that the direction External radiation and smoke exhaust cause heat loss. Now we can use efficient, environmentally friendly and non-corrosive cleaning agent to clean gas-fired boiler. The cleaning agent completely dissolves the cleaning scale, so that the tube of the equipment can be exposed to the original metal color, and the influence of scaling and biological algae sludge can be reduced. At the same time, it can peel off iron oxide and ferrous oxide, prolong the service life of gas-fired boiler and reduce energy consumption.
Dec 20, 2018 · Instead, a boiler turns water into steam. Boilers can be used to not only heat water, but also heat your home and even generate power. Boilers heat water very quickly, and like hot water heaters, are available in tanked and tankless versions. However, unlike hot water heaters, some boiler systems come with a hot water storage cylinder.Online chat
Hot water boiler systems are equipped with a pressure gauge and an automatic pressure reducing valve that will add water to the system if the pressure drops. Despite the pressure reducing valve, owners should be familiar with the standard PSI of their hot water boiler system and should check the pressure reading regularly.Online chat
Steam vs. Hot Water. The main difference between a steam boiler and a hot water boiler is the amount of energy each uses. A steam boiler must burn more fuel (gas or oil) to raise the temperature of its water to boiling level, and this makes hot water boilers more energy efficient, using approximately 25% less energy than steam boilers.Online chat
Steam & Hot Water Boiler Systems By: Greg R. Wayman, Certified Real Estate Inspector Made out of cast iron, boiler systems were made to withstand the test of time. Nicknamed after battleships for their similarity in material, strength, & durability, it is not uncommon to find an old boiler system still going strong 50 years down the road.Online chat
Central heating - Wikipedia. A cheaper alternative to hot water or steam heat is forced hot air. A furnace burns fuel oil, which heats air in a heat exchanger, Fuel oil can be automatically fired in a central heating system and requires no ash removal and little maintenance of the combustion Overview· History· Energy sources· Calculating output of heater requiredBoiler ManufacturerOnline chat
The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.Online chat
There are basically two main types of feed systems : Open feed System; Closed feed system ; Open Feed System. A open feed system is found in a system with an auxiliary boiler, which is generally on a ship with a diesel engine. In an open feed system, steam from various systems comes to the condenser and gets converted into water.Online chat
Jun 25, 2014 · The system suffers from water hammer. Water hammer is so destructive it can actually pull pipes out of fittings. It can also destroy air vents and steam traps. Water hammer blasts open holes through which water will flow to the outside. And then you have to make up that water back at the boiler. Get to the source of the water hammer and get ridOnline chat
