boiler pre heaters in cement plant pressure

2, pressure P, the unit is "Mpa";

3, steam (or superheated steam) Temperature q, in degrees Centigrade. Hot water boiler expressed in terms of outlet temperature and return water temperature. Another area of ​​the heating surface of each grate area, fuel type, fuel consumption, water temperature, total drag, with the wind (the wind drums) the amount of exhaust gas temperature and the like.

4, evaporation: long-term continuous operation of the boiler in the premise of ensuring safety, the number of steam per hour produced, called the evaporation of this boiler. Evaporation also known as "output" or "capacity", the commonly used unit is "t / h" (t / h).

The most common industrial boiler pre heaters in cement plant pressure combustion resolve combustion industrial boilers is a factor in selection of the boiler will be taken into account. 1. The diffusion combustion advantages: This combustion is not premixed, but the gas nozzle mouth interdiffusion, and then combustion. Combustion is relatively simple, relatively stable flame. Diffusion combustion disadvantages: due to a longer flame, it is prone to the phenomenon of incomplete combustion, will produce more carbon monoxide and nitrogen oxides, to the full use of the boiler fuel, to enhance the thermal efficiency boilers, and it is difficult to meet emission standards boiler. 2. The advantages of the premix combustion mode: premixing air and gas, the heat transfer multi-mode radiator, the intensity of heat transfer improvement. The advantage of using this method is that the combustion flame combustion clearer, and higher thermal efficiency. Premixed combustion disadvantage: the ratio of the premixed combustion in claim accurate fast burn rate, burn sufficiently uniform radiant heat transfer efficiency of the high flame temperature below 1200 deg.] C, all complete combustion gas temperature and NOx production low, condenses, good heat recovery efficiency high. 3. A flameless combustion space before the combustion method of uniformly mixing the combustion gas with a gas boiler. When using this method, no need to obtain a gas in the air surrounding the combustion of oxygen required for the process, and only air mixture reaches the combustion zone to achieve complete combustion of the moment. In selecting the combustion mode when the need for combustion of different strengths and weaknesses, compare options, one good way is also advantageous to the combustion boiler to achieve full combustion, improve thermal efficiency and reduce the effect of emissions, therefore, careful selection is very important.

Battle blue horn sounded, emissions of sulfur, nitrogen and oxygen compounds gradually strict national requirements. To improve the quality of the environment, but also the people a blue sky, in all industries around the environmentally friendly product revolution, Hainan Sinochem Pharmaceutical companies are no exception. By the company investigation and comparison of boiler pre heaters in cement plant pressure products, in March 2017 signed a six-ton ​​steam-cleaning integrated condensing gas boiler and steam fast boiler. Tested and post feedback, the boiler equipment installation qualification, operating normally, and successfully passed the inspection by local quality inspection departments of the boiler.

(A) General requirements: 1. In submitting applications should be an independent legal entity. 2. Where the application for a Class A boiler pre heaters in cement plant pressure manufacturing license of the enterprise, application should hold Class B boiler manufacturing license, and should be more than five years of B-class boiler production history. 3. Proposed business license application approved trial produced A-class boiler products. 4. Production and operation status, without design, manufacturing quality of a major accident.
