production complete fuel coal hot water boiler

The boiler must be sampled and tested to determine whether the appearance, quality, flash point, viscosity, acid value, carbon residue and moisture content of the heat transfer fluid are in conformity with the quality certificate provided by the heat transfer fluid production plant. At the same time, it also provides the basis for monitoring the change of medium quality in future operation. The heat transfer fluid will be injected into the furnace and expander with a pump to test the qualified heat transfer fluid. When the oil pump injects the heat transfer fluid into the system, it should check the furnace body again, use the heat equipment, the drain valve of the piping system, whether the oil release valve is closed or not, so as to avoid the loss of the heat transfer fluid. At the same time, open the exhaust valve one by one on the pipe and furnace body to remove the air until it is closed when there is an outflow. When When the oil level appears on the expander liquid level meter, the heat conduction liquid is stopped, then the circulating pump is started, and the cold circulation is carried out. The existing dry dust removal and wet desulfurization of boilers are not suitable for the treatment of high wet flue gas of coal water slurry, because the water vapor in the flue gas of coal water slurry is as high as 36%, and the water content of some coal water slurry is more than 40%. It is impossible to consider only dust and sulfur dioxide. Fangkuai Boiler Co., Ltd. has developed a dedusting product through multi-expert research and experiment, successfully using a large amount of water in coal water slurry flue gas as a carrier to capture dust and sulfur dioxide by cooling, reducing dewatering, and capturing dust and sulfur dioxide. Dust removal and Desulfurization reach the Best of Boiler Effect. The dust removal effect has reached the user's satisfaction. The welding of coal-fired boiler must be operated by the welder who holds the qualification certificate of welder for boiler pressure vessel. Welding dimensions meet the requirements of design drawings and process documents, weld height is not lower than base metal, smooth transition with base metal. There are no cracks, pores, craters and slag in the weld and heat affected zone of the oil-fired gas-fired boiler. Pipe hole weld edge bite depth not more than 0.5 mm, total length (sum of both sides) not exceeding 1 / 4 of tube perimeter, and not more than 40 mm. The boiler construction strictly complies with welding operation rules and other standards and relevant regulations, and makes a good record of construction welding. Record for the record.

More than 40 representatives from various industries across the country gather together in the group headquarters, systematic training and study and visit. Training excluded from the boiler system principles, common faults, maintenance meaning three aspects, the system elaborated from design, manufacturing to installation, commissioning, maintenance matters should be noted that several stages, delegates took the floor, the actual situation of the unit, asked in detail about the future direction of maintenance work required effort.

Why supervisory inspection-free steam boiler steam boiler characteristics can exempt? According to the "Steam Boiler Safety Technology Supervisory Regulations" provides that the normal water level of boiler water volume less than 30L in the boiler does not belong to the scope of the surveillance. When the normal water level of boiler steam boiler water volume is only 27L, like installing a home water heater as safe. So steam boilers belong to exempt boilers. You can avoid the security of small steam boiler What are the benefits? 1, you can not build a separate boiler room, can be placed in the basement, roof and other places 2, do not have a full-time duty Boilermakers (conventional boiler requires certified fireman) 3, eliminating the need for a year dealing with government departments, burning more peace of mind coal steam boiler What are the advantages over conventional steam boiler? Coal-fired steam boiler, is lower than conventional coal-fired steam boiler safety running costs, fast start, no registration and annual inspection, firing five minutes produce steam. Coal-fired steam boilers suitable for use in what place? It can be used in hotels, factories, hospitals and other occasions. The hotel can be used as a steam boiler steam laundry places, canteens and other uses. As plant steam for a steam boiler may be used in the process. Steam boiler can be used as a hospital to disinfect hospital use. Free supervisory inspection characteristics steam boiler: The supervisory inspection-free steam boiler water volume is less than the normal water level 30L, within the exemption permits boiler use a range of countries that use the certificate without going through the boiler. Furnace is equipped with a built-in separator, to solve the problem with the water vapor, more to ensure the quality of design, high degree of automation, personalized steam, all programs are concentrated on a button, extraordinary fool fuzzy control, each operator convenience. Boiler operating system using automatic intelligent electronic control system for the automatic control of all operating states can glance. You can observe in the display to the boiler work state, state boiler water level, steam pressure state level, pump operation status, fault alarm status, allowing you to keep abreast of boiler operating conditions, use more confidence. Using high-quality components all piping and instrumentation connections are made of stainless steel or copper pipe connections, electrical appliances are the most well-known of West Germany Electric, safe and reliable, luxuriously equipped. Multi-chain security features. Products fitted with a boiler inspection by checking the safety valve, pressure controller overpressure protection against boiler due to excessive pressure caused by the explosion; as well as low level protection limit, the boiler will stop automatically in case the water supply is stopped to prevent the phenomenon of dry boiler electric heating element damage even lead to burnout. Leakage protection so that safety of operating personnel and equipment more secure, even when a short circuit caused by improper operation of the boiler, the boiler will automatically cut off the circuit if leakage current and timely protect the operator and control lines. Easy to install, easy to use products factory have passed strict debugging, users only need to connect the power supply and water, as long as the boiler to fill the fuel inside the boiler to enter the automatic running state, without complicated installation. Scientific design, beautiful appearance cabinet scientific design, internal design structure is reasonable, maintenance is extremely convenient. Boiler shell CNC CNC cutting and hemming a molding process, work fine; shell surface temperature after spray treatment, durable, aesthetically pleasing appearance. The main feature of the supervisory inspection-free steam boiler 1, for a wide range of environmental protection, in line with environmental requirements; 2, economy using the latest energy saving technology can save about 50% of the monthly cost of using highly efficient thermal insulation materials, heat loss is very low fuel savings; 3, having a water safety, overpressure, over temperature protection features, safe and reliable; 4, simple practical boiler structure, small size, easy installation and maintenance, long life; 5, convenience can select any number of automatic computer-based digital display phenotypic two kinds of control, easy to operate, less failure, easy to use; 6, adjustable load can be adjusted as desired within the rated range; 7, this series boiler has 0.4MPa (4 kg), 0.7MPa (7 Gongjin), 1.0MPa (10 kg) of three kinds of steam pressure, steam production from 30KW to 2160KW a total of 27 kinds of specifications models for users to choose according to the needs, can also be custom designed for specific users ; coal, oil, electric, gas steam boiler applications: washing ironing industry: dry-cleaning machine, dryer, washing machine, dryer, ironing machine, iron and other packaging equipment for use Machinery Industry: labeling machines, standard sets of supporting the use of Biological Chemical Industry: supporting a fermentation tank, reactor, sandwich pot, mixer, emulsifier and other equipment used in the food industry machinery: tofu machine, the steam box, sterilization tank, packing machine , coating equipment, sealing machine and other equipment for use in other industries :( oil, automobile) steam cleaning industry (hotels, dormitories, schools) steam or hot water supply, (bridges, railways) concrete curing and so on. Steam boiler steam moisture content too much harm.
