Natural gas boiler is a kind of thermal energy conversion equipment, which uses natural gas, liquefied gas, city gas and other gas fuels as fuel to burn the heat released from the furnace, heat the water in the pot, and make it vaporize into steam. Water in a pot (drum) is constantly heated by the burning of gas fuel in the furnace to heat up the temperature and produce pressurized steam. Because the boiling point of water increases with the increase of pressure, the pot is sealed, and the expansion of steam in the boiler is restricted to produce pressure to form a thermal force. Strictly speaking, the steam of a boiler is heated to saturated water and vaporized in the drum at constant pressure. It is widely used as an energy source. Natural gas boiler heating In order to protect indoor warmth and human health, so when choosing natural gas boilers, safety issues are very important, and quality issues can not be ignored, only with good quality, in the use of more assured. Some services can also be done better, the choice of heating is customer satisfaction. Understanding natural gas boilers is certainly a need to know the sales situation of the products, if the natural gas boiler reputation is good, it is still very good in comprehensive aspects, worthy of consumer choice, the conversion of performance and thermal energy can also be consulted. There will be no problems when used like this, and there will be no need to worry about electricity during installation The pressure is not enough. Natural gas boiler shut-down method: after stopping the powder feeder, blow the primary duct for 5 minutes before stopping the oil gun. Oil guns should be blown one at a time, not multiple at the same time. After blowing the gun, ventilate the furnace of natural gas boiler for 5 minutes for 8 minutes, and the air volume is not less than 20% of the rated load. To remove combustible material from the furnace. According to the fuel, natural gas boiler can be divided into natural gas high efficiency fired steam boiler, city gas steam boiler, coke oven gas steam boiler, liquefied petroleum gas steam boiler, etc. According to the structure form, it can be divided into vertical steam boiler and horizontal steam boiler. Natural gas boiler is shell type Full wet backflow three-way pyrotechnic tube structure, flame combustion in large combustion chamber micro positive pressure combustion, complete extension, low combustion heat load, high combustion heat efficiency, effectively reduce the exhaust temperature, energy saving and consumption reduction, use more economical, The heat absorption strength of the boiler is improved by adopting the structure of corrugated furnace tank and threaded smoke pipe, and the heat exchange surface is expanded to meet the need of heat expansion. It is scientific, reasonable and durable.

Gas boiler safe operating procedures: gas-fired boilers this kitchen I believe we are not unfamiliar fishes it. But this thing is not so easy, and sometimes improper operation causing very serious consequences, so the gas boiler rules is very important. That in the end this is how the specific operation of it, if you want to know, quickly told us with a look. 1. All personnel must be familiar with the operation of the boiler performance and safety knowledge of the boiler operating certificates. This post is strictly prohibited non-operating personnel. Duty should be strictly in accordance with the operating records and do a good job shift recording, the security situation and the device should shift change operation tests, carried out. When the shift to check the boiler is intact. 2. Boilers and safety accessories should be inspected, and in the period. 3. Kai blast furnace gas furnace ready ① Check if the gas pressure is normal, not too high or too low, open the door of oil and gas supply section; ② Check whether the pump Sheung Shui, or opening the purge valve, until the Sheung Shui so far. Open the Water Supply System for each section of the door (front door section Sheung including pumps and boilers); ③ check level gauge, the water level should be in the normal position, the water level gauge, a water level required color plug in the open position, the water level to prevent false, if water can be manually Sheung; ④ check valves on the pressure pipe, must be opened, the wind deflector must all flue opening; each knob ⑤ checks the control cabinet are in their normal position; ⑥ high efficiency fired steam boiler check valve should be in the closed state hot water boiler circulating pump outlet valve should be turned off; ⑦ checking water softening equipment is operating properly, a variety of indicators to create a soft water meets national standards. Open the power ⑴; ⑵ startup burner; ⑶ purge valve on the drum, is completely out of steam, the off; ⑷ inspection hole into the boiler, and the hand hole flange valves, the leak was found to be fastened, tight as the solid leakage maintenance shutdown; ⑸ pressure rise when 0.05 ~ 0.1MPA, replenishment, sewage, water supply systems and sewage screening test device while flushing water table; ⑹ when the pressure was raised to 0.1 ~ 0.15MPA, flushing pressure gauge trap; ⑺ when the pressure was raised to 0.3MPA, "fire load / small fire" knob to "fire" to strengthen the combustion; ⑻ when the pressure was raised to 2/3 of the operating pressure, start warming air supply tube, slowly open the main steam valve, to avoid water hammer; ⑼ drain valve is completely closed out of steam; ⑽ after all the drain valve closed, slowly open the main valve to open, and then half a turn; ⑾ "burner control" knob to " Auto "; ⑿ level adjustment: adjusting the water level (to manually start and stop the pump) according to a load, low load level should be slightly higher than the normal level, high load level should be slightly lower than the normal level; ⒀ steam pressure adjustment: adjusted according to a load combustion (manual adjustment Fire / small fire) ⒁ combustion state determination, determines the amount of fuel atomization air ⒂ observation condition exhaust gas temperature, smoke, temperature control is generally between 220--250 ℃ The flame color, smoke color, while observing the chimney exhaust gas temperature , concentration, adjusted to the optimum combustion state. ⑴ Open the power; ⑵ start the circulation pump; ⑶ slow circulation pump outlet valve; ⑷ startup burner; ⑸15 min "" Load fire / small fire "bit color button is turned to" fire "" ⑹ "burner control" knob spin to "automatic." 5A normal shutdown: hot water boiler ① "fire load / small fire" knob to "small fire"; ② off the burner; ③ close the fuel supply valve; ④ ⑤ closing dampers boiler after the temperature dropped to 50 ℃ , the circulation pump outlet valve closed. ⑥ stop circulation pump

After installation and commissioning fast Boiler professional and technical personnel, two hot water boilers to provide our bodies quickly into the orbit of the normal operation. Meanwhile, the design of energy-saving equipment also effectively improve the thermal efficiency of the boiler, saved us a huge amount of fuel costs. --customer feedback

6MW YQW series gas-fired thermal oil heater project for food industryThe rapid development of the food industry is inseparable from the strong support of the boiler system, which is one of the important production line equipment for the plant extraction process. Founded in 1995, Damin Food (Zhangzhou) Co., Ltd. is an international enterprise group specializing in deep processing of natural plants which integrates R&D, production and sales. Its products are exported to the United States, Japan, Europe and other countries and regions. It is an international supplier of many large-scale food and beverage, restaurant chain and health care products pharmaceutical companies.Damin Foods is committed to producing healthy and natural products and creating a healthy lifestyle that returns to nature. Therefore, Damin Foods attaches great importance to its own green development, and adheres to the environmental protection concept in the selection of boiler equipment. It plans to introduce environmentally friendly boilers that use clean energy natural gas as fuel. After understanding their actual needs, ZOZEN tailored the technical solution for Damin Foods: newly construct four sets of 5 million kcal YQW series thermal oil heaters. This series of gas-fired thermal oil heaters has the characteristics of high temperature and low pressure. In the process of plant extraction, high temperature steam is used to complete the sterilization process of plant concentrate, which fully meets the temperature requirements of Dagu food production line. The tail of the heater is also equipped with waste heat recovery devices. By recycling the waste heat of high-temperature flue gas, the heat energy loss is greatly reduced, and the overall thermal efficiency of the heater is increased to over 95%.
