Dzl Series Fixed Grating Water Fire Pipes Boiler

Big fuel gas dzl series fixed grating water fire pipes boiler gas boiler gas consumption reasons of natural gas, large air consumption situation may arise in use, the air consumption of the main reasons, what does? 1, gas boiler heating lack of unified planning, which is the root cause of the impact of energy savings. The problem is that there is an important design factor causing congenital high energy consumption, low management level is the main cause of high energy consumption. 2, in the development plan, the gas heating boiler, new and piece together a comprehensive understanding of the problem of insufficient planning, housing construction; they must attack;, dispersed along a small hot water heating boiler room became; expediency; to form a gas-fired boiler the size of small rooms, small gas boiler capacity is causing a large energy consumption birth defects, and this; two small; the fact that the formation is indeed closely related to the lack of unified planning, and piece together the transformation because it is difficult to avoid unplanned blind. 3, for quite some time in the past, the emphasis in various heating design safety considerations, make the results of the design heat load actual value is typically much larger than needed, and thus a multi-radiator, gas boiler, large pumps, large diameter, priori form; big horse car; situation, low-load, high-volume operation is widespread. This is due to the mismanagement of the designer heating operation, fireman low level of technology factors affecting heating do not know enough to worry about heating is not, will not dare to cut down the heat load, resulting in equipment is still too large, creating a vicious cycle. 4, through a lot of practice and testing, in terms of common understanding has been great progress in the actual design and the increasingly close. Existing gas boiler heating operation and management, mainly built housing distribution sector professional management and self-management units into two categories, in general management level is relatively low. 5, good professional management of some cases, units from the tube by a small number of high level, in the most basic high energy consumption, low efficiency under the conditions. In addition, the prevalence of social importance heating, and energy-saving awareness is weak, new technology, new achievements rarely used, long stay in the extensive management experience, failed to improve the refinement of scientific management. Learn the big gas boiler gas consumption knowledge of the reasons, I believe you must have a lot of harvest it, hope this helps you make better use of gas-fired boiler.

The competition, the segment is slowly 45 contestants only a female welder, most of the other competitors from China Electric Power Construction, veteran welders in the petroleum, petrochemical, and other large number of country prefix units, with a very rich practical operation of work experience. Faced with numerous welding expert, slowly segment did not flinch and fear, but to actively exercise their welding ability, the old master who humbly ask to try a variety of different welding methods, and repeat the training to do practice makes perfect. By her welded dzl series fixed grating water fire pipes boiler parts forming the United States, no weld defects neat; in her station, welding clean, neatly stacked tools, work order. It is because of her usual work down to earth, hard work and practice, lay a solid foundation for the success obtained.

Boilers are widely used, and there are some unique problems in China. Although imported dzl series fixed grating water fire pipes boilers are used in some plants, the pipeline is still carbon steel, oxygen corrosion and CO2 corrosion are serious, resulting in the problem of iron ions in condensate water exceeding the standard is very common. High content of iron ion water is an unsafe factor in boiler, which causes pit erosion and pitting corrosion of boiler wall, and causes boiler perforation to be scrapped.

Heating and hot water dzl series fixed grating water fire pipes boilers are mainly two uses hot water bath boiler fuel using steam turbine power conditioning subsystem - Frequency electrohydraulic control system similar to the feedforward - feedback cascade control system. Master regulator proportional regulator, the steam turbine power - frequency electro-hydraulic control system of a frequency corresponding to a difference amplifier which corresponds to droop ratio with the steam turbine, the size represents the size of the hot water boiler with a load capacity, proportional band the larger, the more hot water boiler with a load capacity; the sub-controller uses proportional-integral regulator, the steam turbine power - the power conditioner frequency electro-hydraulic control system corresponding to; the amount of fuel introduced into the feedback signal, and the steam turbine power - frequency turbine electrohydraulic control system incorporated in the pressure signal corresponding to a first stage, which is rapid elimination of the hot water boiler fuel quantity spontaneous disturbance. There are heating and hot water boiler bath for two purposes. Hot water boiler by circulating hot water circulation pump hot water holding tank, the tank hot water heating cycle can be achieved bath object; hot water boiler by circulating hot water circulation pump heating conduit, through the heat sink (radiator) people can achieve heating requirements; hot water boiler and hot water circulating pump with heat exchanger can be achieved bathing and heating dual function. Water speed before the hot water boiler should not start too fast, usually in winter no less than 4h, the other seasons 2 ~ 3h, especially in the beginning of the water should be slow. Hot water boiler water temperature is generally 50-90 ℃, so that the temperature difference between the feedwater entering the drum drum wall temperature is not more than 40 ℃. Not completely cooled gas hot water boiler, water temperature, mutatis mutandis, the drum wall temperature, or should slow down the speed of the water. When feed water enters the drum, the first wall half always in contact with the drum, when the feed water temperature and drum wall temperature difference is too large, the influent fast speed, upper and lower walls of the drum, the inner and outer wall will have a greater expansion difference, resulting in a large drum to additional stress, causing deformation of the drum, when severe cracks. Since the thick-walled drum, slow expansion, the wall of the tube is connected to the drum wall is thin, expanded rapidly. When the gas hot water boiler water temperature is too high or too fast, uneven expansion will cause the weld cracks, damage to the gas hot water boiler.
