DZL Series Horizontal Type Water Fire Tube 1 ton Steam Boiler
November 5, Ministry of Industry announced the latest "national industrial energy-saving technologies and equipment Recommended List (2018)", the star product of fast boiler - premix wing-type vacuum condensing hot water boiler, with ultra-low nitrogen oxide emissions and excellent energy-saving effect with this honor. "Energy saving" was first presented in the "" Eleventh Five-Year "Plan", the entry point to do by reducing energy waste and reduce emissions in terms of both economic development and adhere to common development and environmental protection. Since 2015, the state has increased efforts to promote energy-efficient technology and equipment, mechanical and electrical products each year in all types of energy-saving aspects of the work of judges, party fast with a strong technical ability to create many types of environmentally friendly products, as the heavy regulars honor.
First, look at the regular boiler manufacturers
The Fangkuai boiler believes that the correct adjustment of the supply and draft air volume is conducive to environmental protection, and it can also save energy under certain conditions. The Fangkuai boiler can first determine the suitable value of carbon dioxide or oxygen at the measuring point above the adjustment of the supply air volume. It is then compared with the measured value to determine if the supply air volume needs to be adjusted. If the boiler and flue are running under negative pressure, the outside air will leak into the flue from the wall or door of the furnace, obviously to the back of the flue, in the smoke. The higher the value. Therefore, when monitoring the supply air volume of boiler with carbon dioxide meter or oxygen meter, the influence of air leakage before measuring point should be considered. In order to determine the appropriate value of carbon dioxide or oxygen at the test point, it is difficult for the boiler to obtain the best excess air coefficient exactly in actual operation. The general regulation is to reduce the air flow as much as possible, that is to say, the manager reduces oxygen or increases carbon dioxide as much as possible, on the premise that there is no flame, dark red instability or black smoke in the combustion. In addition to adjusting the air flow into the furnace, attention should be paid to adjusting the air distribution. Negative pressure is one of the most important operating parameters in Fangkuai boiler. In normal operation, the negative pressure at furnace outlet should be 20? 30 Pa. If the furnace negative pressure is too high, it will cause the furnace and flue If positive pressure appears in the furnace, the flame and smoke in the furnace will be sprayed out of Shanghai, which will not only affect the environmental hygiene, but also may occur personal burn accident. 3. The heat loss of exhaust gas will be increased by the increase of air leakage, and the power consumption of the induced fan will be increased, if the furnace pressure is positive, the flame and smoke in the furnace will be sprayed to Shanghai. Therefore, in the process of combustion adjustment, it is necessary to adjust the air diversion site according to the change of furnace negative pressure in order to keep the furnace negative pressure in a normal value while adjusting the fuel quantity and air supply. When the boiler increases the load, it must first increase the draft air volume, then increase the supply air volume; on the other hand, when the boiler load drops, it must first reduce the supply air volume before reducing the draft air volume. Finally adjust the furnace negative pressure to the required value. Yes There is no draft air volume adjustment problem in micro positive pressure combustion boiler. Fangkuai boiler air volume regulation is easy, can easily meet your needs, sincerely welcome you to consult and negotiate business.
When atmospheric pressure using the direct pressure hot water boiler heating system and water or closed loop. That is, on the boiler body with the atmosphere of the exhaust pipe as a return pipe use, the boiler water pressure is always in full state. This closed loop harm in two ways: The first is when the water temperature is too high furnace, steam generated can not be excreted, so the pressure will continue to rise, explosions and spills can happen at any time. Second, even if the boiler water temperature is not high, it does not produce a large amount of steam, but the role of a circulation pump, the boiler body is subjected to high pressure hot water circulation. The pressure hot water boiler installed in the basement or on the first floor, the hot water storage tank installed on the roof, this embodiment is similar to the boiler to the atmosphere as exhaust pipe return pipe use. Although the boiler is not subjected to the pump pressure applied to the ring, but at all times are under boiler water holding tank to provide a high static pressure, the higher the floor, the higher the static pressure of the hot water.
