high pressure boiler detail com

At 10:00 on September 6 and more, Harbin, a business is the purchase of a new high pressure boiler detail com equipment installation, commissioning process when staff at a boiler pressure gauge index found that the performance of the boiler abnormal, but not so the commissioning personnel when the next step, a sudden loud noise, boiler explosion, a huge flame and furnace pressure debugging of oil spray everywhere, four commissioning personnel are subject to varying degrees of injuries, was taken to hospital for treatment .

Boiler is an energy conversion device, by entering the fuel to the boiler, chemical energy, power, etc., outputs a constant steam heat, hot water or organic heat carrier, to provide support for the heat industries. Meanwhile, the boiler is also a special equipment has a certain risk, when the boiler installation, commissioning, operation, etc., be sure to boiler operation safety first.

Now, Xiao Bian to operational safety considerations gas boiler summarize, we can refer to.

First, start, boost, steam supply

1, before the start of the preparatory work

Internal and external check: Check boiler, burner, a good state of the accessory device; action safety accessories, each of the valves, such as flexible instruments, the correct position.

Check the line voltage to meet the requirements, a variety of normal switch position, respectively, various auxiliary pump starts operating, the burner fan, oil pump is normal.

Boiler Feed: exhaust valve opening, to ensure the normal water level (just below the water level).

2, start

Firstly purging the furnace, induced draft fan suction time is usually about 10 minutes to ensure that no residual gas in the furnace, passing substitutions, and ignition for combustion air supply.

After firing is completed according to the adjustment amount of load required for combustion, the boiler into normal operation.

During startup, to closely monitor changes in water level, water boiler accident or occurrence textile full of water accidents.

Second, the normal operation

1, the water level

Fuel gas-fired boiler water table should be the red line indicating the high, medium and low water level, the operation shall not exceed the maximum safe level or below the minimum safe level.

Rinse water table at least once per shift, when there is suspicion of running water, rinse should always check.

2, steam pressure

Red lines indicate the working pressure gauge should have, so sensitive and reliable, the trap should be flushed at least once a week.

3, safety valve

Safety valve should seal intact, no leakage; once a week manually (or automatically) emission test, and begin start pressure, opening pressure, reseating pressure and test time, participants, etc credited maintenance log book u, for future reference .

4, sewage

Proceed as boiler water quality requirements of water quality testing personnel under the guidance of class 1 or 2 times sewage, sewage incident not too long, generally no more than 10 minutes.

Sewage should (preferably when shutdown), should be closely monitored sewage water level changes, and pay attention to safety at the time of low load, low pressure, high water level.

Many boilers when sharing a sewage mains, while sewage is prohibited.

Third, shutdown

1, the normal shutdown

After normal boiler shutdown should generally be reduced boiler load operation, press the boiler shutdown procedure. Actuated pump water to high water level, pressure steam boiler to be dropped after 0.3MPa flushing water table and sewerage operations, and finally close the raft, cut off the power supply control cabinet, wipe equipment, clean up the environment and health, For water, the water temperature should be below after 70 ℃, before proceeding.

2, emergency shutdown

When the boiler operation in the following situations should immediately shutdown:

Furnace water level drops below the minimum water level gauge visible edges.

Increasing water supply and other measures, but digital still continue to fall.

Boiler water level exceeds the highest visible water table level (full of water), the water still can not see the water level.

All water supply system water pump failure or malfunction, not water to the boiler.

Water gauge or safety valve all the failures.

Endanger the boiler element is damaged and the safety of operating personnel.

Combustion equipment damage, or furnace wall collapse and other red-hot boiler structure is a serious threat to the safe operation of the boiler.

Other anomalies endanger the safe operation of the boiler.

3, maintenance

Before maintenance work should be well prepared, as before entering the drum interior work, must be of sufficient strength to connect all of the metal blocking plate spaced reliable steam, water, sewage and other operation of the boiler pipes, and the drum manholes and hand holes (boiler shell) is opened, so that air convection period.

After the completion of preparations to repair. Should ensure that the quarterly frequency of boiler maintenance and repair of the year.

Advances in technology to the boiler industry into new and innovative ideas, now the boiler manufacturers boiler are easy targets toward the operation forward, but in the use of the boiler, improper operation or other quality problems still exist, these failures will It is causing the direct cause of the explosion boilers. Therefore, when using the boiler must be in strict accordance with safety practices boiler, security incidents strangled in the cradle.

Also, it is in the process of using the gas high pressure boiler detail com, also hope to meet its own requirements on the control. Some devices are above the market need for manual operation, but there are also some equipment can fully meet the intelligence operation, one-button start it can work. Because this operation can reduce its operating costs, but also let users like. And different users have different requirements want it in the work, so there are the more desirable it may be disposed of in the operation, can be changed for different requirements of users.

What pressure high pressure boiler detail coms? Pressure boiler typically used to crowded places bathtubs and community event of an accident, a group of casualties is likely to cause fatal accidents. In the accident investigation, we found that some units in the design, installation and use of atmospheric boilers has many problems, such as the body of the boiler is not provided directly to the atmospheric vent, vent valve installed in the boiler, expansion tank constant pressure boiler, high moisturizing, not according to the characteristics of the arrangement of pressure boiler pipe system, and so on. The so-called boiler pressure means connected in any operating condition, opening the atmosphere, the water level of the boiler pressure gauge to zero (see JB / T7985-2002 & "small boiler water and atmospheric conditions boiler technology"). Boilers are designed and manufactured based on the atmospheric pressure atmospheric parameters, and therefore can not be limited to runs. It is essential and necessary balance pumped from the boiler and water requirements. However, it should be noted that the basic concepts of flow and water pressure. Briefly, water refers to water per unit time by the volume of the designated section, the water pressure is a force per unit area. The two can not be confused. Atmospheric pressure in the boiler is based, zero one atmosphere at atmospheric pressure. Pressure hot water boiler heating, heating systems typically use two methods. The first boiler water is withdrawn from the pump into the heat dissipation surface and directly. After cooling power, returning to the boiler water tank open to form a loop. Second, water is drawn from the furnace, the heat exchanger returns the water tank boiler open loop is formed, the water heat exchanger after pressing into the heat absorbing surface, back to the operation of the cooling heat exchanger.

Working principle and characteristics of the premix high pressure boiler detail com a combined module, the working principle: the premix boiler module, based on user needs and design load size, the number of modular units can operate independently of the integral boiler, through the outer chamber temperature, and monitoring the supply and return water temperature change computing, computer-controlled system may control each of a module, the module automatically adjusts the number of start and stop, so that the heat output always matches the actual heat load demand, and to ensure that each module can be kept in optimal combustion conditions, so as to achieve overall efficient operation of the boiler. Second, the main features: 1, saving fuel. Most ordinary boiler when there is a low load operation, the actual thermal efficiency is much lower than the thermal efficiency of the design defects, when the load fluctuations, will cause energy waste. Premix combustion boiler module due to its simple behavior control, with adjusting the load change fast, flexible, thermal efficiency can be always maintained at 95% (90%), thereby achieving energy efficient operation. 2, stable, easy to operate. Because of the unique premix module boiler operation mode, easy to automate the process of running the operation. Automatic control system of the boiler installation, full automation can be achieved during operation according to the set parameters, the operator is reduced. 3, transportation, easy installation, small footprint. Since the dismantling of the boiler can be like building blocks in combination, therefore, greatly facilitates transport and installation, reducing the footprint, and without foundation boilers, require a lower storey of the boiler room. 4, easy to maintain. Due to the simple structure of the boiler itself, no drums, and other ancillary equipment fan, so running failure rate; and achieve low noise operation. 5, each module backup each other without backup boiler, if the malfunction in the heating of individual modules, has little effect on the entire system.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (72,000 kPa or 1290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
