Use of natural gas give the types of combustion of the boiler, so what can energy-saving? Natural gas boiler. Effective heat value but its low calorific value of about 8500 kcal / cubic its high calorific value of up to 10,000 calories, the extra part in burning Nao process becomes superheated steam with the flue gas discharged out, the exhaust gas temperature can reach about 220 degrees to install a waste heat recovery tube in the flue gas outlet of the column, heated with hot flue gas is pumped into the preparation boiler water, you can save gas more than 5% ,, Thus, in terms of low calorific value of the thermal efficiency of the boiler can be 88% to 92% to 98% to 102% 1, to improve the conditions of the air flow encounters improved gas boiler gas and air two streams communicating condition, and an object thereof is to increase the contact area. The greater the contact area, the greater is the reaction area, strengthen the burning. Specific measures may be air and the gas stream into small strands, so that the two streams meet and intersect with a certain velocity; cell stream of gas (generally a gas) passes through and submerged in another stream of air, and the like. 2, enhance mixing, scrambling combustion gas boilers burning gaseous fuel is a single-phase reaction, ignition and combustion of solid fuels easily than, but the rate and extent of complete combustion is mixed with the combustion gas and air quality are closely related. Better mix, burn more rapidly and completely, the flame is short. Therefore, as long as the stability of the flame is not destroyed, it should enhance airflow velocity gas stream in the combustion chamber outlet or even a baffle at the inlet of a large resistance and the like obstacles, let hitting, red flame, increase turbulence in the airflow to strengthen the mix. 3, preheated air and gas to increase the temperature of gas and air, can be enhanced combustion reaction. It should therefore be preheated using waste heat of exhaust gas and air temperature, thereby increasing the combustion temperature and the flame propagation velocity of the combustion process to be strengthened. 4, rotation of the rotating stream and the recycle gas stream causes turbulence and mixing can be enhanced. Meanwhile, in the center of the rotation will form a reflux stream of large gas back area of ​​the boot cycle, both to strengthen the mixing, also extended the flue gas flow path and residence time within the gas boiler and reduces loss of incomplete combustion. 5, flue gas recirculation in order to improve the combustion gas temperature of the reaction zone of the boiler, the flue gas may be directed to a portion of the high-temperature combustion data, so that the end of the fuel mixed with the burning or combustible mixture, in order to improve the combustion intensity. But take note that the amount of flue gas recirculation should not be too large, otherwise it will dilute the combustible mixture and the hook due to excessive inert substance, but slows down the combustion, pyrolysis and even anoxia, resulting in loss of incomplete combustion gas boiler.

20 tph SZS gas-fired water tube give the types of combustion of the boiler project for chemical industrySteam boilers play a key role in the production process of dye intermediates, proving steam for synthesis, drying and other processes. Tsaker Chemical Group Limited, listed in Hong Kong Stock Exchange, has four business units including dyestuff BU, pigments intermediates BU, battery materials BU and environmental protection BU. Dye intermediates BU, located in Dongguang County, Cangzhou City, Hebei Province, and mainly engages in the production and sale of dye intermediates DSD acid, NTS and dinitrotoluene sulfonate (DNTS). Dye intermediates BU (hereafter referred to as BU) planned to introduce natural gas boilers to response to increasingly stringent environmental protection policies like “coal-to-gas”. Because the environmental protection boilers on the market vary in quality, the BU took enormous care in choosing the boiler supplier. After several comparative studies and cost analyses, the BU was deeply impressed by the excellent products and services from ZOZEN, and ultimately achieved cooperation with ZOZEN. ZOZEN provided them with SZS gas-fired steam boilers after on-the-spot investigation. This kind of gas-fired boiler adopts the structure of membrane water wall for better sealing effect and higher thermal efficiency; In addition, to effectively reduce the NOx emission, the boiler is equipped with a large volume furnace and an advanced NOx burner imported from Europe, so the NOx emission can reduce to30mg/Nm3.

Boilers use common sense should know that now the rapid development of the industrial sector in our country, so many industrial plants and products have been widely used, and now many of the give the types of combustion of the boiler in areas play an important role in the use, you operate What are the basic personnel matters should pay attention to it? each model of boiler is equipped with its own instruction manual before installing and operating staff are familiar with the instructions needed to make sure you master the basic steps of such devices. Due to the use of boiler is very complicated, so the staff usually before induction operation, the factory will carry out systematic training, so that we become more familiar with the relevant procedures. Boiler after a normal start, we must ensure that it is under the auxiliary exhaust valve is closed, if not closed, it may result in serious accidents produced, for example, such devices scrapped, or because the boiler failure which appeared oxidation phenomenon, resulting in explosions and other accidents. When the staff found that in the presence of anomalies running the operating pressure of the boiler, he must be stopped for the first time, it may make otherwise stick with very serious consequences. Clean it regularly for this type of equipment, because it may run and work for a long time, resulting in lower overall efficiency, and will accelerate failure. If the running time, the sudden appearance of a power outage, this time, the staff needs to fire immediately sealed, and the fastest cold oil replacement valve is opened, so as to slowly put the high slot among the cold oil among the replacement of boiler tubes. For everyday use of the boiler, cleaning and regular maintenance and inspection, we need to send professionals, the general staff remember not to operate on its own, or it may cause more serious consequences. With the development of the industrial sector this year, making the boiler as well as products for use in many areas were frequent, proper operation and use, can really play its thermal effectiveness, further providing reliable protection for businesses, manufacturers of production efficiency, making enterprises harvest more substantial economic gains.
