glass kiln waste heat boiler case study

Gas-fired glass kiln waste heat boiler case studys used chemical characteristics of gas-fired boiler which uses chemical characteristics of what? Improved technology, gas boilers wide variety of applications in the field of production requirements, replaces the traditional combustion boiler, put forward their own characteristics, not only has significantly improved performance, but also relatively easy to operate. First, the system is simple, compact, durable and does not require gas boiler slag equipment, dust and other auxiliary equipment, ventilation and small boilers, water supply, control and auxiliary equipment disposed on the chassis, may be medium-sized factory assembled, thus greatly improving the efficiency. Due to the compact structure, the structure of the content is simple, greatly simplifying the tool. During operation of the machine easier and more convenient. Second, high thermal efficiency, environmental gas is a gas combustion boiler, the high clean fuel, environmentally friendly technology, combustion efficiency and the exhaust gas temperature, substantially the same as the large-capacity industrial boilers, exhaust pollution is very small, can reduce the combustion of different energy. Can effectively improve the heating efficiency and reduce pollutants. Follow the development of environmental protection is one of modern production and processing equipment. Third, automated operation with the deepening of modern gas boiler technology and perfect, it can fully meet the requirements of automated operation, to better meet the lighting, automatic fire-fighting requirements and other related content. On the one hand greatly improves the safety of the production process, on the other hand greatly reduce the labor costs. Powerful automation, to further meet the needs of modern enterprise intelligent and efficient production.

There economizer gas pipe on the glass kiln waste heat boiler case study, the amount of wear and if it has reached thirty percent of the wall thickness, it is necessary to replace. There will replace Similarly superheater, reheater water wall tube, wall thickness abrasion to reach 25 percent.

Structure designed according to the glass kiln waste heat boiler case study pressure, provided through the top of the large pores, the boiler operates at atmospheric pressure, away from the danger of explosion; boiler furnace using computer simulation to optimize the design, the size of the boiler is fully optimized, so that coordination aesthetic aspect.

At 10:00 on September 6 and more, Harbin, a business is the purchase of a new glass kiln waste heat boiler case study 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.
