hot water boiler in china

Use of natural gas 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.

The gas-fired boiler will have a series of chemical and physical reactions in the furnace during its operation. In the process of use, it will effectively form its hard and dense scale on the heating surface. This will directly lead to the reduction of heat transfer efficiency and corrosion factors under scale, which will lead to the reduction of boiler water wall furnace heat absorption.

Hefei Limin Pharmaceutical Co., Ltd. Nanjing Military Region, formerly the backbone of pharmaceutical companies, the main drug is slowly swallow rather teabag, relying on advanced R & D platform to carry out contract manufacturing, OEM OEM and other business cooperation. China's environmental protection development trend began to take shape, many environmental policies have been put forward for a positive response to the national environmental policy, Limin Pharmaceutical decided to introduce a gas station steam boilers. After an investigation of the boiler market, Limin Pharmaceutical fast boiler is strong comprehensive strength and wealth of experience working for many years in the pharmaceutical industry to attract, party fast according to the actual needs of customers for its recommendation of one of Taiwan 4 tons of steam condensate gas-fired steam boiler (WNS4-1.25-YQ).

Wherein the gas boiler WNS WNS boiler which is horizontal, tee, wet-back fire tube boiler after wet the boiler space of the water jacket means of flue gas behind the soaking furnace turned. Repair and maintenance of the rear of the boiler is very difficult. The main body of the boiler furnace, boiler and chimney housing components. Typically corrugated furnace, a pipe is threaded. Purpose is to increase the heating surface of the boiler, furnace efficiently absorb thermal expansion and contraction. Boiler to prevent cracks. WNS gas boiler features a large furnace, corrugated furnace technology using the advanced design of large-scale furnace technology, in the original traditional design, expanded the hearth diameter, increasing the radiation heat transfer area, the heat transfer to the main boiler radiation heat transfer, not only reduces the heat transfer. Second and third line load, but the fuel combustion, reducing harmful gases. Meanwhile, the ripple tank furnace technology in the high temperature zone of the furnace, not only increases the radiation heat transfer area, and has a blocking effect on the movement of smoke, the heat radiation effect is more obvious. Corrugated furnace can only improve the overall strength of the furnace, and can automatically compensate for thermal expansion stress of the furnace, to avoid defects such as weld cracking due to thermal stress. 2, a high heat strengthened threaded tube designed and optimized heat transfer technology smoke velocity, thermal efficiency of the boiler and the decrease in the output of the extended run time, thereby realizing a compact structure, with 10% overload. 3, the climate compensation techniques demand heating (hot water boiler in china) technology has changed the conventional isothermal manner, i.e. according to the outdoor temperature changes and user demand for heat, the efficiency of the heat source temperature of the boiler water automatically optimized. And the thermal energy required for heating the heat boiler provided the user is balanced, that is, high outdoor ambient temperature, boiler water temperature down automatically, low outdoor ambient temperature, boiler water temperature is automatically raised.
