PM2.5 is frequently mentioned in recent years, and its main premise was that the formation of NOx, according to the latest research results show in Beijing, PM2.5 and NOx emissions due to the formation of more than 50% of the total proportion of PM2.5. Because of a large area of ​​coal to gas projects in recent years, the country's use of gas-fired boiler china suppliers more than 50 million units in the Beijing area, gas boiler emissions will soon exceed the vehicle, as the primary sources of NOx in Beijing, so Beijing EPA first proposed the strict NOx emission standards: Beijing new boiler to perform emission limit of 30 mg / standard cubic meter for boilers with high-pollution fuel combustion zone ban, the implementation of emission limit 80 mg / standard cubic meter . The standard is much higher than the European emission standards for boilers, to the world's most demanding emissions standards in Southern California to move closer to the boiler.

How much is the current mill electric heating steam boiler china suppliers, steam boilers lot of mills are used more gas as the main form, but still in some places gas resources is not very good, so you need to take power as a medium. Textile mills in the procurement of electric heating steam boiler is also to go through the full contrast, in this case, I will choose to compare their own boiler plant products. Recently, there is a textile mill to be fast boiler consulting, want to buy steam boilers, currently determine the form of electricity, but still want to boiler manufacturers here to help account for the price, and fast boiler technician for the textile mill after a detailed understanding of the situation, out of accounting data show that the mill electric heating steam boiler with two 2t on it. Currently, the types of boilers in the fast side of the price of 180,000, and that the total purchase cost is around 36 million. Therefore, the textile company for electric heating steam boiler is how much money has been detailed understanding.

Gas oil furnace gauge acceptance and prohibit the use of instructions for conducting oil furnace oil furnace gas this kind, since both sites boiler china suppliers products, is one of the sites keywords, therefore, requires a comprehensive knowledge and understanding. Moreover, it is also a common oil furnace type. Therefore, only familiar with this kind of boiler, we have the right to use, so a lot of benefit to themselves. 1. Gas oil furnace acceptance for this kind of a gas oil furnace oil furnace, which work in the acceptance, the main, are: First, when a gas oil furnace transported to the installation site, the manufacturer should be based on factory inventory, an inventory of its parts, whether there are missing and so on. Then, according to the boiler drawings, review of equipment, mainly to check its associated integrity. For example, the large boiler, during transportation, whether there is damage or deformation such problems. 2. Gas oil furnace gas pipeline for oil furnace installation, in which the pipeline installation, requirements mainly refer to "Heat Transfer Fluid heaters Safety Supervision" in, and should refer to product specifications, as well as the process of FIG. to carry out. For the line connection port, in addition to the flange on the connection should be used to this kind of welding. In addition, the pipeline arrangement, there should be a slope, typically from 2% to 3%. In the high line, an exhaust port shall be provided, at its low due outfall. For straight line pipe, if the length is more than 20m, then there should be a thermal expansion joint. 3. conducting oil furnace gas gauge, when the circumstances under which can not be used? In the gas oil furnace, pressure gauge is an important instrument, but if some situation, then can not continue to use its specific terms, it is as follows: Case 1: broken glass on the pressure gauge, or its dial scale is unclear, unrecognizable. Case 2: Pressure gauge seal is damaged, or it exceeds the test period. Three cases: for a limited gauge nail stop, if there is no pressure, the pointer can not limiting, the staple at the back. If the nail is not limiting, pressure gauge, in the absence of pressure, which is the distance between the pointer and the zero position, more than a predetermined allowable error range.

Steam boiler china suppliers pressure gauge should pay attention to matters 1, rated steam pressure less than 2.45MPa steam boiler and pressure gauge accuracy not only in 2.5; rated pressure steam boiler child or equal to 2.45MPa, the pressure is too spread made not less than 1.5 level. Dial gauge diameter of not less than 100mm, in order to ensure the operation of the operator to see the surface of the pressure value shown. 2, should draw the red line on the dial gauge steam boiler, he pointed out that the maximum allowable working pressure. 3, the steam boiler pressure gauge should be provided at a convenient place to observe and purging, and to prevent the high temperature affected, freezing and vibration. 4, steam boiler pressure gauge should check at least every six months once the check should seal. 5, the pressure gauge connection tube steam boiler should leaks steam leakage phenomenon, otherwise it will reduce the pressure instruction value. 6, a steam boiler gauge scale element should be compatible with the measured working pressure, working pressure, typically 1.5; 3 times, preferably 2 times. When no steam boiler gauges, pressure gauges or pressure damage did not meet the requirements of the apparatus, boiler steam pressure gauges of the following circumstances, should stop using: 1, the surface glass breaking or blurred dial scale; 2, no seals , damage or seal verification period exceeded; 3, no pressure gauge pointer finite bit staple staple can not be restored to the limit at infinite set of bits from zero gauge pressure exceeds the pressure data bits garment allowable difference?; 4, the jump table or a pointer leak; 5, other effects gauge accurate defect. The use of the accumulator: the accumulator for a hydraulic accumulator system intermittent mechanical, hydraulic fluid may be stored in the actuator output when a batch or a low speed, and the actuator requires a large flow of fast-moving, as an auxiliary energy providing oil to the system together with the hydraulic pump, oil pump and thereby achieve miniaturization of the entire hydraulic system, to achieve the object of absorbing the impact energy sudden change fast opening and closing valve and the hydraulic load, the system generates a pressure shock, pet cause vibrations and noise, and even damage the machine. The accumulator can be alleviated, which absorb fluid shock absorber pressure pulsation absorbing accumulator, and reducing the pressure pulsation and flow pulsations of various pump, thereby reducing system noise and vibration. Having a damping effect of the gas spring accumulator, it can be used to absorb the mechanical vibrations between the body and the traveling wheel of the vehicle and the like. The accumulator can be balanced upright actuator (hydraulic cylinder) and gravity load decreases when the potential absorption into hydraulic energy store, while generating the rate-limiting resistance; upright when the actuator rises, releasing the original absorbing energy accumulator , together with the pump oil to the hydraulic cylinder, in order to achieve balance and energy.
