Fangkuai Boiler is a clean-up hot selling fired steam condensing boiler equipment based on various excellent scientific and technological advancements, focusing on product development, manufacturing, and manufacturing that are more efficient, environmentally friendly, and energy saving, and meet the basic national conditions of environmental protection in China. In order to promote the rapid development of the heating furnace manufacturing industry, people-oriented, consider the specific requirements of customers in the manufacturing industry for heating furnaces in various industries.
Multiple protection devices take you through the oil steam hot selling fired steam condensing boiler oil steam boiler water level protection, boiler water level gauge plate supporting one to two, should always be compared with each other, findings indicate inconsistency shall be corrected immediately. Class water level should be flushed, to determine their true level. While the water level comes electrode rod can accurately capture level signal to an alarm or a pump control. Steam pressure protection, the pressure controller: selection of high sensitivity of the pressure controller, the pressure is high, or low levels of signal to the electrical switches, automatic control chain protection or other control lines. Using pressure controllers and electrical contacts, the vapor pressure can overpressure alarm; single adjustable pressure controller or dual fire burning fire the actual operating pressure. Safety valve: safety valve is the last line of defense to protect the boiler, the boiler pressure exceeds the limit, according to the set pressure relief valve design with the school, the exhaust steam pressure relief, to ensure the normal operation of the boiler. Flame protection, having imported burner flame protection means, combustion function is to detect, when the ignition failure or extinguish combustion middle, immediately off the burner into the oil (gas) solenoid valve, the blower continues to operate at this time, the furnace was purged of residual internal combustible gas, after 20 to 30 seconds purge, and various auxiliary blowers automatically cut off power, the boiler operation stops. Self-locking power protection case, the boiler shutdown immediately burst self-locking power interruption, if the current power is restored, the boiler will not start at any time, you must reset release self-locking, to re-start the ignition.
SZS steam hot selling fired steam condensing boiler capacity is among 4 ton to 35 ton; WNS steam boiler capacity is among 1 ton to 20 ton. We also supply gas and oil fired power plant boiler. Higher capacity steam boiler is also in our product lists. Just I do not writeit in this passage.
Boiler cleaning the necessity and significance of the hot selling fired steam condensing 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.
