disadvantage of waste heat recovery boiler

Glossary disadvantage of waste heat recovery boiler and boiler work content for boiler plant, its foundation and the important points, is a part we have to learn, but at the same time, do not forget some of the difficult problems that, or everyone in the use boiler, etc. may produce confusion, which is the focus of study because it is also very important, it will affect the overall understanding of the product, it can not be sloppy. Below that, without further ado, to immediately proceed with it. 1.4 tons of boiler, which uses natural gas, then the annual consumption is about how much? 4 tons of boiler, if you are using natural gas, the consumption in the previous year, according to the specific size of the load, to decide. If a full load, and consumption of gas which is 84 cubic meters per hour. So, it can be calculated specific annual consumption. 2. boiler, what is the excess air ratio? What should be calculated? Excess air ratio in the boiler, which is specifically, it refers to during operation, the ratio between the actual air consumption and theoretical air requirement boiler. And, it is a relationship with the type of combustion equipment, and boiler fuel type, etc., will be affected by these factors. 3. In the boiler plant, for its workers, mainly what work contents? For this kind of boiler power plant boiler, which is related to workers on job content, mainly include: (1), there should be someone responsible for aspects of the operation of the boiler equipment, maintenance and management, so that the responsibility to implement into practice, and to ensure safe and economical operation of the boiler. (2) boiler, which during operation, to deal with operating parameters at any time to observe and analyze the need for appropriate adjustments. For verification, testing and finishing of boiler work, should be a corresponding record or report. And, during operation, should take the necessary security measures to ensure safety.

Repair and maintenance of gas way gas steam disadvantage of waste heat recovery boiler steam boiler is a special heating device, on the one hand, in the long run, has been in a poor working environment. On the other hand, if the design and production of boilers, installation and maintenance of unreasonable, will make the boiler abnormal situation, such as leaks, deformation, corrosion and other adverse circumstances, if we can not be checked and ruled out timely, will gas steam boiler safe operation occurred bring security risks. So, boilers companies, should pay due attention to safety and economic operation of the boiler, the boiler will be able to play a role. Boiler maintenance is carried out in order to prevent unnecessary accidents, and can effectively reduce and prevent a general failure to reduce the cost of investment in gas engineering, and also improve the efficiency and service life of the boiler, the boiler ensure safe and economical run, create more benefits for the enterprise. Routine maintenance of primary, secondary and maintenance. A maintenance operator is required, in the daily work, the boiler and the auxiliary equipment inspection records, mainly gas equipment, water gauge, safety valve, fans and other equipment, the state of the device must be recorded for the query. Two maintenance is based on a maintenance on the boiler and auxiliary equipment and relevant examination, do regular routine maintenance work. Gas-fired steam boiler has lots of accessories and instruments, valves composed of many accessories has its crucial role, if functionally related elements unreliable, or part can not be achieved, it will adversely affect the safe operation of the boiler, there are mainly maintenance-related content: safety valve. Can guarantee the safety valve at a predetermined pressure of the boiler, the boiler steam pressure exceeds the predetermined if, the valve will sound an alarm to alert the operator to take appropriate measures; another effect can be reduced to the boiler is, blood pressure, to ensure the normal boiler run.

Fang faster work on clean fuel disadvantage of waste heat recovery boilers more than twenty years, whether it is research and development or manufacturing fields have achieved remarkable results. The launch of the "Euromonitor 5" series boilers, the company's new low-nitrogen boiler, using advanced FGR combustion technology, nitrogen oxide emissions below 30mg / m3, our first-tier cities can be used normally. Remote monitoring system is to attract the attention of the participants. Jumping curve data, real-time display operating status boiler; detailed data analysis and fault early warning program, Fang fast "black technology", making the boiler to get rid of "silly Big Ben rough" image and become intelligent high-tech incarnation.

Diesel Oil fired Steam Boilers are widely used in paper industry, power plant, chemical industry, leather industry, glass plant and so on to supply steam or generate electrics. High efficiency diesel oil fired steam disadvantage of waste heat recovery boilers can provide stable steam during paper manufacturing or glass manufacturing process. Its stable and good performance can meet different industries needs.
