The oil and gas water tube boilers produced by ZBG have a thermal efficiency of up to 98%, and use FGR flue gas recirculation technology and staged combustion technology to achieve low nitrogen emissions from boilers with NOx emissions below 30 mg/Nm³. The highly automated operation of the boiler, high safety performance, low boiler installation investment, and low operating costs make it a very popular oil and gas boiler in foreign markets.
Fuel steam boiler fuel steam boiler: Features: 1. Reburning fuel steam boiler corrugated liner tee horizontal central fire tube structure absorbs most of the heat, high temperature flue gas when the flue gas reaches the wheelhouse, may be reduced to 720. deg.] C, lower than 400 deg.] C or more other structures, thus greatly improving the the operating conditions of the boiler tube sheet area evenly heated. The present invention reduces the scale of production, prolong the service life; burning back at the center of three-loop configuration, when the return uncombusted portion two loop complete combustion at high temperature, the fuel can be burned again, generation of NOx is reduced, saving energy, effective protection of the environment. 2. The use of threaded pipe, a corrugated liner, advanced technology and good thermal expansion properties, clever use of the thermal expansion of the inner bellows and cold shrink, strong turbulence and good interference properties, high heat transfer coefficient, high thermal efficiency. three. Expansion tank located in the upper boiler, the water level to facilitate inspection and an exhaust port having a diameter of 400mm, to facilitate inspection and maintenance the boiler internals. 4. The introduction of Western Europe original combustion engine and automatic computer control devices, reliable operation of computer disk unit over-temperature protection, water protection, fault protection and self-flame burner malfunction alarm functions, ensure that the boiler safe and normal operation; respectively combustion machine the first stage ignition and the second stage ignition control, and record the operating time of the burner, in order to ensure economical operation of the boiler, reducing fuel consumption. Temperature control set free, clock function, the oil level control, automatic fault-point display, 04: 00 to facilitate the daily time switch functions, operation and management. The direct heating to produce hot water, the heat exchanger may be used in a multiple stage machine. The heating temperature can meet different requirements, to provide a hot water bath. 6. It can be used with a heat exchanger, in order to meet the needs of high-rise buildings; water-cooled grid, cool, less investment, effective, and long service life. 7, after the wet structure, hinged front panel open structure, easy maintenance and repair. Eight. Atmospheric design, absolutely safe; smoke-free clean, in line with national environmental requirements. 9. The outer mirror stainless steel or cold spray, nice.
Boiler cleaning the necessity and significance of the boiler after a long run, the inevitable emergence of scale, corrosion problems, these problems are due to the generation of scale, so that the heat transfer deterioration, resulting in reduced efficacy boiler. It is difficult to achieve nominal evaporation; and since the heat transfer is deteriorated, such that the metal overheating, under pressure boiler, furnace tube bulge occurs even explode; poor thermal conductivity, so that the fuel consumption is increased, increased operating costs, boiler shortened life expectancy. Therefore, the boiler scale, should take the necessary cleaning methods. Of the boiler system operated at optimized state, it must be specialized chemicals treatment of boiler system water system: to remove scale, rust and anti-corrosion treatment: 1 chemical cleaning: adding a chemical cleaning agent to rust in the system , dirt, cleaning oil dispersion is discharged, reduced to clean metal surfaces; 2, routine maintenance: boiler scale inhibitor is added, to avoid rusting of metal, to prevent the crystalline precipitate calcium and magnesium ions. Boiler cleaning in two parts, part of convection boiler tubes, superheater tubes, air heaters, waterwall tubes scale, rust cleaning, i.e. water boiler water treatment, we used the final Li Jing Ling descaling operation, neutral cleaning technology cleaning operation, relatively low cost; cleaning of the part of the outer tube, i.e. the cleaning of the boiler furnace, we used high-pressure water jet cleaning technology, it is possible to achieve good results. 1, the cleaning operation may be neutral at neutral or weak alkalinity (pH 7-12) conditions, the water does not change the operation of the boiler a predetermined state index, do not stop cleaning, cleaning can reduce the loss caused by the stop, this is a the only signs of cleaning. 2, security theory and practice of running the boiler have proven non-erosive, washed acid-free cleaning under neutral conditions, the corrosion rate is less than the water washing of the corrosion rate of the metal, no corrosion damage to the metal. 3, non-toxic and pollution-free operation of the Spirit is a green cleaning products, boiler blowdown COD after its cleaning. BOD. The pH full compliance with national standards. 4, easy to use drugs added to the water supply can be, without a separate professionals, post operator can operate, it can be widely used. 5, a significant saving, the cleaning process in which water is the normal production water, unlike dispensing additional consumption pickling, passivation, and a large number of repeated washing of freshwater resources consumed. High pressure water jet cleaning technology uses water as the medium, so that the water system by special equipment to produce multi-beam, multi-angle, high-pressure water jets of different intensity. Internal cleaning object fouling, plugging, or be completely cut surface adhesion, crushed, pressed and washed in order to achieve complete cleaning. Whatever the fouling deposits, high pressure water jet cleaning device for cleaning, can be completely removed, which considerably metal color. It does not require chemicals, or corrosive flux, safety, and environmental protection. Boiler air preheater, waterwall, superheater, economizer heating surface and the like due to clogging of the exhaust gas temperature, boiler efficiency is lowered, increasing the wind electrical energy consumption; the fan will cause severe blockage afford pulling negative pressure oxygen furnace not enough, boiler forced outage. Using high pressure water jet technology, the cleaning effect is obvious. Equipment from high pressure water pump, water hoses, high pressure gun, special nozzle and other components. Cleaning process: water pressure via a high pressure pump to the 50 ~ 100Mpa, via line transferred to the system actuators work surface, forming a bundle of fine high-pressure water emitted from the nozzle with a high pressure water jet but powerful strike capability, which exit velocity up to 380m / s, the heating surface fouling rinse. The high pressure cleaning technology to clean, easy to adjust, cleaning equipment to be non-corrosive, non-polluting the environment, the effect is obvious characteristics, is an effective and a good way to save money and effort, especially suitable for solving air preheater clogging, severe coking furnace heating surface slagging problems. Generally reduce exhaust gas temperature of 4 to 12 degrees, the main improved reheat steam temperature of 0.5 to 5 degrees, to reduce electrical energy consumption for the wind, and early detection of creeping inflation, under scale corrosion risks, the unit safe and economic operation of very help.
