Gas-fired asme standard steam boiler for edible plant abnormal situation, how should we deal with it? When we use gas steam boiler, failure or abnormal phenomena it is inevitable, but in order not to affect the normal use, in the event of a problem gas steam boiler to be timely processing solutions, then the face of all kinds of circumstances, we should how to handle it? Share some of the ways we deal with unusual circumstances. If only gas steam boiler circulating pump abnormalities, such as its current decreases, the pump outlet pressure back to zero, which indicates no oil pump is idle, it may be caused by oil vaporization. Yang identify the reasons therefore first vaporized measures; such as clogging of the filter circulating pump bypass opening evacuated immediately clean the filter; heat transfer fluid as a result of added aqueous or decomposed gases are not excluded in the system, should immediately open the vent an exhaust valve. Circulation pump pressure constant, the current increases and the flow drops, deterioration of the thermally conductive fluid, the viscosity increased, should be replaced or regenerated. New heat transfer fluid as a result of decomposition of aqueous or excluded gases in the system, should immediately open the vent valve of the exhaust gas. When the current is lower than normal circulation pump, the circulation pump efficiency is decreased, the flow rate decline may be heating pipes plug fouling, stainless steel chain should be cleaned. If the gas steam boiler before and after the filter increased in pressure, the pump inlet pressure drops, the filter may be stuck, the opening of the bypass, disassemble and clean the filter. In addition to its low furnace outlet temperature liquid phase heat carrier, mainly for lack of heat fouling problems, it is timely soot blowing. Gas steam boiler grate more common problem is stuck, there are reasons including breaking grate or the grate off loose pins; coal grate has stuck to metallic inclusions; arched grate; slag is sinking the tip of the grate stuck. In response to this phenomenon, the required reverse hand grate plate debris removal, replacement breaking grate after the start, then jammed as startup, stop the rotation of the reasons detailed inspection to resolve. But also to re-adjust the adjustment screw on both sides of the grate tension, if still does not work, we need to replace the sprocket.

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.

Classification and characteristics of oil-fired boiler which when the weather gets colder, people will choose different heating methods, which have a more convenient way is oil-fired boiler, but many people do not understand his usefulness, then together below take a look. Category: oil-fired boiler is the practical use of fuel, the boiler various boiler with diesel fuel and waste oil, his overall construction and arrangement of the gas boiler is similar to a common classification of mechanical and steam materialized style. Features: Multi-Fuel bottom of the pot is made of the holding furnace bottom is inclined to the back wall for holding furnace bottom, in order to obtain good combustion characteristics. This is not the kind of boiler for the gas pipeline, also want to be able to lower the cost of the normal operation of the boiler, then oil-fired boiler is a good choice. Oil-fired boiler is an important sign of progress now era, the purpose is to serve humanity well, according to further improve the people's needs.

Concern the 2014 APEC summit (referred to as APEC), held in Beijing Huairou Yanqi ecological demonstration zones on November 10, multinational leaders are to attend an important meeting. The summit venue construction attaches great importance to environmental protection work. In selecting venues boiler heating and hot water services, to the summit to make clear that emissions of nitrogen oxides boiler, perform extremely strict NOx emission standards around the venue --60 mg / cubic meter. Carefully selected, nitrogen oxide emissions technology in the international advanced level of fast Boiler become the ultimate winner. Gas hot water boiler fast boiler developed the production of ultra-low nitrogen oxide emissions, gas asme standard steam boiler for edible plant, integrated condensing boiler has become the summit heating and hot water designated products.
