factory price superheated steam boiler
According to instructions, "Neijiang City in 2017 and phase out coal-fired boiler desulphurization facilities construction program of work", before the end of this year, the city built-up area will be fully phased out in Neijiang City, 10 steam tons / hour of coal-fired boilers and a total of 46 units. Among them, a small city in district out of coal-fired boilers 26, and phase out coal-fired small boilers Dongxing District 15, Neijiang Economic Development Zone small coal-fired boilers out of five. At the same time, accomplish four Chuansha Qi Industrial Co., Ltd. Two 20 tons of steam / hour or more coal-fired boiler desulphurization facilities. A ban on new urban area 20 steam tons / hour of coal-fired boilers, other counties (cities, districts) in principle, the new 10 steam tons / hour of coal-fired boilers. Out of the way including demolition scrap, coal to gas, coal and electricity upgrade boiler swap with large capacity.
We understand that the new Neijiang 20 tons of steam / hour for coal-fired boilers built-up areas, the new 10 steam tons / hour or less fixed asset investment projects in other areas of development and reform, economic and information technology departments will not be approved, approval and filing, environmental protection departments at all levels shall not pass environmental impact assessment, quality supervision departments at all levels do not accept the installation told not arrange supervision and inspection, no special equipment issued registration certificate. Quality supervision departments at all levels cancellation of special equipment for the boiler has been out of use registration certificate to prohibit the production of boiler manufacturers boiler does not meet industrial policy.
Fast wns side boiler fast wns advantages square boiler technology core (1) housing a high thickness compared with the conventional package boiler, boiler housing insulation effect has been greatly improved condensed steam, the boiler 2mm thick printing plate, and insulation felt and wool and aluminum silicate composition are combined. (2) water level detected by the addition of 5 low water level is detected directly inside the protective tube boiler water level, greatly improving the reliability level detection system. Detecting the differential pressure level, forming multi-level protection system (3) adding a low water level detection means detecting the scale drum inner protection, can close the boiler water shortage alarm processing and to ensure the safe operation of the boiler; outer alarm level, the differential pressure constituting a plurality of water level detecting levels of protection systems. (4) automatic operation, ease of operation and the automatic fire detection automatic adjustment control of the combustion flame can be achieved, the inlet temperature of the boiler can be displayed directly to the condenser, direct knowledge of temperature, current level and other operating parameters. Flue gas monitoring means to automatically detect the exhaust gas temperature of the boiler, the boiler combustion control easier. Advantages Fast wns boiler side - side core technical features fast wns finned tube boiler: the heat exchange tubes with fins, the heat transfer tubes heated area increases, the efficiency of using the aluminum compound to improve heat transfer material, reduce corrosion damage. Fine grinding tube surface, contact heat resistance is low, waste heat generated by friction to reduce heat transfer tubes of high stability, easy to wear and prolong the service life characteristics controllers: Advanced mainly reflected in: processing units belonging to rely on other, now custom processing equipment, processing data by testing internal waves bile. Before processing, a line should be drawn from different waves of contraction to be increased correspondingly, the position of the processing line. First, the first wave was heated to 700 ℃ ~ 750 ℃, and then to a top wheel through. After molding, the size should be tested and refined appearance amounts, on the side to be cut according to the size of the drawing after passing. There are two sets of equipment. The device uses the principle of local heating and rolling, rather than the traditional corrugated press furnace. It has fewer molds, precise dimensional control, easy operation, a wide range of advantages workpiece.
Notes boiler blowdown and the specific steps boilers use a long time there will be all kinds of dirt, these vexing dirt may also affect the use of the boiler, the boiler should be how to clean up the dirt of it? What issues should pay attention to it? Described briefly below: 1. In order to prevent the water inside the boiler slag scale accidents caused by it, we must ensure that the internal flow of water quality, water alkalinity reduction furnace, when the furnace water alkalinity greater than 20 mEq / l, should be sewage. Note that when the sewage: 1, when two or more than two boilers use a sewage, the sewage is prohibited simultaneously. 2, if a boiler in the repair, so that the boiler should be isolated from the manifold open. 3, blowdown, the water level should the boiler at high and low loads. Second, the blowdown steps: 1, open the drain valve, preheated sewage mains, pipelines After preheating, the big valve, the discharge is completed, immediately close the drain valve. 2, blowdown, if there is an impact sound in the outfall passage, the discharge valve should be closed immediately until small sound disappears, and then slowly open the valve play, sewage for too long, the drain valve is fully opened time is generally not more than 15 seconds , so as not to affect the boiler water circulation. 3, sewage and cycle emissions should water quality monitoring personnel to determine the general sewage class at least once a regular basis. These are the boiler blowdown precautions and specific method, if it is found to be timely boiler fouling detergent treatment, if ignore them, over time, it will not only affect the efficiency of the boiler, but also a security risk.
Superheater tube boilers and boiler superheater its two operating state, if the squib phenomenon, then what specific reasons? And what is the dry and wet operation of the boiler? The main purpose of the two issues raised, in order to be a good and comprehensive solution, so we will be able to have a thorough understanding of, and at the same time, let's deepen their understanding of the boiler. Cause Analysis 1. Boiler Superheater tube. Boiler, if superheater appear squib phenomenon, its specific reasons, the analysis and summary boiler manufacturer box boiler, the conclusion is: One reason: superheater tubes, long-term operation in the over-temperature condition, even if overtemperature modest, but also the mechanical strength of the pipe material will be lowered, and so the creep speed, then there a thick bulging phenomenon, until the burst. Two reasons: the presence of foreign matter superheater tube, and a blocking phenomenon has occurred, so that the boiler combustion becomes unstable, so that the deterioration of the heat transfer pipe, the local temperature is too high, and further, the high temperature squib. Dry and dry-wet operation of the boiler 2. The boiler operation: this, in block boiler manufacturer boiler opinion, is that when the boiler load is above 35%, since the generated factory price superheated steam boiler is larger than the flow rate of the water wall, such that the superheated steam flows through the steam trap, but this time there is no water in the steam separator, so called boiler runs dry. Wet boiler operation: For this, according to the boiler block boiler manufacturers introduced the dry run is the opposite. Which means that when the boiler load is less than 35%, less than the steam in the boiler water wall flow, then the steam separator in the water. Therefore, this condition is called wet operation of the boiler. In fact, these two states boiler can be interchangeable, and will be affected by burn rate. If the steam flow through the steam trap becomes superheated steam, together with the effect of the temperature controller, and an effective control of the boiler feedwater flow it is correct and can achieve a smooth transition of the state.
