With the rapid modernization of industry, the scope and quantity of boilers are increasing year by year, which makes the safety of boilers become an unavoidable topic, which is also a difficult problem that puzzles many enterprises. The safety measures of industrial boilers can protect the property and personal safety of our enterprises and individuals from damage. Here are some measures to prevent accidents of industrial boilers.
1. Observe the material, strength, type of connection, welding and cold-working components of the main pressurized parts of the industrial boiler drum, such as housing, head or tube plate, furnace liner, etc., to meet the design and manufacturing regulations. It is necessary to pay more attention to the fire tube boiler because of its larger diameter, more pressure components, more complicated connection types and so on.
2. During the maintenance of industrial boilers, the caustic soda brittleness, serious corrosion deformation and groove cracks should be highly vigilant, carefully checked, and the quality of maintenance must be guaranteed to prevent sudden tearing due to lack of strength or crack expansion.
3, operators must bear in mind: serious water shortage, do not feed water, so as not to overheat the wall of the pot, not as expected and brittle. Even high-quality and durable industrial boilers should be paid special attention.
4, industrial boiler safety valve and other safety accessories must always be sensitive, accurate and reliable. An important common cause of explosion in most small boilers is the absence of safety valves or failure of safety valves to cause overpressure. If the safety valve is normal and operated under low pressure, the explosion can be completely avoided.
5, pay attention to the links that are easy to be ignored. Cooking, bathing, heating, hot water boilers and tea stoves are also frequent accidents. These boilers are small in volume, low in pressure, more in the living department, often not noticed and paid attention to, it is easy to become a weak link and loophole in boiler safety management, so special attention should be paid to it.
1, for a gas steam water tube boiler, the point is not a fire, the chimney must then on Furnace After purging, before a second firing.
2, in order to prevent a gas explosion, gas boilers require not only before the start of the boiler furnace and flue gas purging channel, and the need for a purge gas supply pipes. The gas supply duct purge medium is typically an inert gas (such as nitrogen, carbon dioxide, etc.), and the purge of the boiler furnace flue with a certain flow rate is the flow rate of air as the purging medium.
Water level gauge is mounted within the drum water level indication on a meter gas condensing steam water tube boiler, fireman may at any time to monitor changes in the water level in order to determine the amount of water in the furnace conditions.
Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of tourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast steam water tube boiler steam signed a 0.5-ton electric heating steam boiler which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .
Carryover of impurities from boiler water to steam is also inherent to boiler operation. Though separation devices in drum boilers remove most water droplets carried by steam, some residual droplets containing small amounts of dissolved solids always carry through with the steam. Also, at higher pressures, there is some vaporous carryover.Online chat
Water Tube Boiler Working Principle: To understand the water tube boiler working principle, we will discuss the simple above water tube boiler diagram. This boiler consists of a steam drum (Upper Drum) and a mud drum (Lower Drum). Feedwater with the help of a feedwater pump enters the steam drum.Online chat
The Tru-Steam Fire-Tube Boiler is a package steam generating system, factory assembled and tested. It consists of boiler pressure vessel, combustion and water feeding equipment and controls, all coordinated to form an integrated design unsurpassed for safe, quiet and dependable steam generation.Online chat
Boilers come in all different types, sizes, and shapes and are classified by configuration of the furnace, or firesides, and the watertubes, or water holding volume. The two main boiler types consist of firetube and watertube boilers, and deciding which of the two will best fit your process needs is not as easy as it may seem. It is like comparingOnline chat
PROCESS DESIGN OF STEAM BOILERS (PROJECT STANDARDS AND SPECIFICATIONS) Page 3 of 45 Rev: 01 April 2011 SCOPE This Project Standards and Specifications is intended to cover minimum requirements for process design of field erected water tube boilers. REFERENCES Throughout this Standard the following dated and undated standards/codes are referred to.Online chat
Water Tube Boilers Boiler water passes through the tubes while the exhaust gases remain in the shell side, passing over the tube surfaces. Conclusion Boilers are classified into fire tube or water tube boilers depending on whether the heat source is inside or outside the tubes.Online chat
As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. As the dissolved solids become more and more concentrated, the steam bubbles tend to become more stable, failing to burst as they reach the water surface of the boiler.Online chat
A Steam boiler is a steel pressure container in which water under pressure is transformed into steam by the use of combustion. In other words, the boiler is just a heat exchanger which uses radiant heat and hot flue fumes, released from burning fuel, to produce vapor and hot water for heating and processing loads.Online chat
Water-tube boilers have water-containing tubes heated externally by the fire produced in a furnace that burns gas or another type of fuel. As a result, they produce steam by transferring the heat received to the water circulating inside them.Online chat
Troubleshooting Steam Heating Boiler Problems For this reason, many steam boilers have a low water cut-off valve that senses when water levels are dangerously low and turns off the burner beneath the boiler. If the boiler ran low on water, was refilled, but the burner will not turn back on, it is likely the low water cut-off valve needs toOnline chat
Water tube boilers are designed with water inside the tubes of the boiler and hot gases surrounding the tubes. As the water temperature increases, steam begins to develop and travels to the upper portion of the boiler, typically called the steam drum. The cooler water travels through the down-comers to the mud drum where the water will beOnline chat
Bagasse fired water tube steam boiler is horizontal type double drums water tube boiler with high steam quality, the combustion equipment is chain grate. Sitong boiler takes several breakthroughs on boiler design, such as membrane water cooling wall, low thermal inertia design, and water cooling combustion chamber. Except bagasse, this series steam boiler could also burn other biomass fuelsOnline chat
A water-tube design basically works in the opposite way: The water flows through a tube that is surrounded by hot flue gas. For most applications, a water-tube boiler is far more efficient because it produces steam in minutes and requires far less time to power up and blow down. Water-tube boilers are also usually more compact, require far lessOnline chat
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubesOnline chat
Construction: A horizontal steam and water drum: this is the main part of the boiler.It is supported by a steel structure at a certain height and is independent of brickworks. The size of the boiler drum is small as compared with the boiler drum of a fire-tube boiler of the same capacity.Online chat
