If the configuration boiler fuel gas or dual fuel burners, then the boiler is oil or gas boiler. Fuel gas-fired boiler is a more general concept, fuel gas-fired boiler is divided into water boilers, hot water boilers, 2th fired steam boilers and thermal oil boiler, according to their own use to select a different fuel gas-fired boiler time of purchase.
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.
Henan gas boiler surroundings in claim (1) prohibition of the various stacked Henan combustible gas in the boiler room, not allowed to bake anything Henan gas boiler and steam pipes. Cotton wipe oil equipment, oil rag to a safe place. (2) prohibit incineration in Henan gas boiler waste paper, waste wood, linoleum and other waste, to avoid causing a chimney fire fly, ignite surrounding combustibles. Around (3) Henan gas boiler can not be an ignition source is not close to the other heating boiler pipeline equipment. In addition, we must pay particular attention: Once Henan gas boiler appears dry (red-hot), turn off the power immediately, open all exports, remove the burner. Prohibited immediately cold water into the furnace body should wait until the natural cooling. In order to avoid or reduce the casualties caused by the explosion of a gas boiler and its social, economic losses, we can adopt a more efficient boiler explosion-proof alarm system. For example, possible to detect the concentration of combustible gas leak sensors and alarms. Domestic and now have been developed using a gas sensor, a gas leak can be utilized, for measuring combustible concentration to alert the boiler furnace. The alarm high sensitivity, fast response time made of semiconductor material, the combustible gas sensor feel gas leak alarm immediately. Water spray system can be used as preventive measures early boiler fire and explosion. With the development of technology, artificial intelligence, and more high-tech will be applied to prevent an explosion in Henan gas boiler in the past.Free Chat
