kelapa biomassa shell boiler
The daily operation of the kelapa biomassa shell boiler adjustment (oxygen papers): oxygen is an indicator to monitor the boiler furnace excess air ratio, it changes the furnace combustion conditions are closely related, if the external loads, combustion, cited air supply, air leakage parameters such as the case where the constant amount of oxygen to the furnace to correspond to fuel heat release. Generally, under stable conditions, furnace heat release amount matches with the supply amount of oxygen remains substantially unchanged, the main steam pressure is stabilized at a certain value accordingly. Oxygen is increased, the furnace described exotherm less than blowing amount, then the pressure will drop, it is required to increase the fuel supply amount, to maintain the pressure. Because of the inertia of the drum and the heat storage capacity of the combustion equipment, the main steam pressure change rate is slower than the rate of change of the amount of oxygen, therefore, concerns the amount of oxygen changes can be determined in advance direction of the pressure change, thereby adjusting the pressure of the functions ahead of the effect of regulation, which is the main basis for regulating a pressure stable operation.

Special equipment manufacturing enterprises, power enterprises should strengthen boiler pipe source control, in strict accordance with the standard provisions of China's relevant laws and regulations and orders technical conditions agreed to carry out boiler pipe design and manufacturing, procurement orders, admission acceptance, inspection and testing, installation and commissioning work, resolutely eliminate substandard or counterfeit boiler pipes enter the field of electricity production; to strictly implement the special equipment safety supervision and management regulations, establish and improve the technical archives and long-term care, to ensure that relevant information can be traced back.
Special equipment manufacturing enterprises, power companies are finding there are significant quality and safety risks of boiler tubes, to report to the local market regulators, power management departments and the National Energy Board sent energy regulators, and to take effective measures to thoroughly rectification to ensure the safe operation of generators . Provinces, autonomous regions and municipalities and Xinjiang Production and Construction Corps Market Authority (Hall Commission) should work together with the same level of power management departments, the National Energy Bureau sent energy regulatory agencies and other units, the organization of supervision and inspection, supervision and hidden rectification, effectively preventing security risks.
We should take some effective measures to increase the use of gas hot water kelapa biomassa shell boiler of each machine in the course of people's need to take care of, otherwise there will be some unnecessary trouble. So, for professional gas hot water boiler, how to take effective way of protecting it? In normal use, always pay attention not only to the effect of gas hot water boiler should also take effective measures to increase its use. life. 1. maintain this pressure curing method is suitable for closed more than a week but does not fix the boiler. You can first of all the water drained pot, then scale furnace cleaning and re-add qualified demineralized water. Regular use of fire to warm water temperatures in summer gas hot water boiler is kept at 10 degrees. So, it can not be frozen in winter; water boiler should also periodically, to maintain the pressure in the boiler reaches the normal value, to prevent air from entering the drum. 2. Maintenance wet method is suitable for such maintenance has been closed less than a month's gas hot water boiler. After the shutdown, the water leaving the boiler a predetermined time, the internal cleaning impurities; second, all inlets and valve should be closed, completely separate from the operation of the boiler; and a special preparation of mercury. The basic solution was placed in a boiler protection; micro-wave oven should be used regularly in order to maintain the heated drying surface during the entire maintenance. 3. Maintenance dried dry for long maintenance downtime gas hot water boiler. Need to drain water and to remove impurities, followed by the complete separation of operation in the boiler; a suitable amount of moisture absorbed by the desiccant in the boiler, and require direct contact with a heated surface not desiccant boiler. Within a month, you should check whether the desiccant in the boiler and no corrosion. The method of the above three aspects is cured gas hot water boiler. When using the boiler, regular inspection, pay special attention to corrosion of steel. If long ignored corrosion problems, it will have unpredictable consequences. Therefore, maintaining high stability is essential for the gas hot water boiler.
Why low nitrogen kelapa biomassa shell boiler more environmentally friendly easy to use? Low nitrogen boiler is a new boiler, through sophisticated rational design allowed a higher thermal efficiency and flue gas emissions in line with national environmental standards, no pollution on the natural environment. So now many companies purchase equipment from an efficient and reliable supply of low nitrogen boiler manufacturers to replace traditional boilers. Here's a look at why the low nitrogen boiler will be more environmentally friendly to use. 1, the outer loop techniques using smoke emissions standards prompted by the use of this technique, the boiler can be low nitrogen tail portion of the boiler flue gases, combustion air inlet is sucked into the machine through a stainless steel flue gas duct into the combustion air after mixing the furnace and the like. In this way can effectively reduce the temperature of the combustion zone, while reducing the oxygen concentration in the combustion zone, and ultimately reduce thermal NOx generation amount, it is possible to lower NOx emissions so that the flue gas of the boiler in a low nitrogen with conducive to the protection of the atmospheric environment. 2, the combustion surface using the premix achieve ultra-low emission surface premix combustion technology is an advanced "seamless woven wire" technology, special alloy woven into a wire mesh, a low nitrogen gas and air when combined boiler after precise mixing can be generated in the metal short fiber tufts wire mesh type flame, the combustion is more uniform, the ease of formation of a local high-temperature region, it is possible to effectively suppress generation of thermal NOx, the combustion can not only play the role of silence, but also great effect to achieve ultra-low emission 3, using the heat insulating material to reduce heat loss Q table of low-nitrogen stainless steel pipe used as a boiler flue gas duct, in order to energy saving, the use of very low thermal conductivity of the rock wool insulation insulation layer on the outer pipe , whereby heat radiation loss can be ensured a small boiler, and beautiful and practical.
