Henan gas treatment condensing boiler operation in the secondary combustion Accident Henan condensing gas boiler, deposited in the rear of the boiler flue gas condensing Henan combustibles (soot, carbon black) re-ignition combustion phenomenon called secondary combustion, also known as Henan condensing gas boiler flue tail and then burned. It will backpass severe, air preheater, induced draft fan and other equipment economizer even destroyed. 1. Henan condensing gas boiler secondary combustion phenomenon (1) a sharp rise in exhaust gas temperature, chimney to take smoke, fire or even smoke. (2) changes drastically furnace pressure, positive pressure occurs. (3) severe flue enclosure dark red. (4) when there is an air preheater, a sharp rise in the temperature of the hot air, pressure instability. (5) blast doors sometimes the tail action. Cause 2.Henan condensing gas boiler secondary combustion (1) poor atomization burner, oil, gas and incomplete combustion into the rear of the boiler. (2) combustion improperly adjusted, with insufficient wind or with the wind unreasonable. (3) Henan condensing gas boiler startup, shutdown during low furnace temperature, the unburned fuel in the furnace. (4) When shutdown or boiler fire, air gun valve is not closed. (5) the combustion chamber negative pressure is too large, too late to make the gas burn it into the rear of the boiler. (6) Long-term non-stop cleaning backpass furnace, accumulating a certain amount of soot or carbon black. (7) through the air preheater flue or leakage. 3. The gas processing condensed Henan secondary combustion boiler (1) should immediately stop the gas, stop the wind, shutdown. (2) closing the flue, and a baffle duct around the door opening, is prohibited to start sending, induced draft fan. (3) immediately extinguishing device into steam, carbon dioxide or other fire extinguishing means, (4) Strengthening Henan condensing gas boiler feed water and turn on the water, open the valve or economizer recirculation tube to protect the economizer is not burning. (5) When the exhaust gas temperature close to the temperature of the injected steam, or less than 150 deg.] C over 1h and stable openable inspection hole inspection, after checking element determines an ignition source, before the fan starts ventilation and cooling. (6) when the temperature drops below the flue 50 ℃, check before entering the flue tail heating surface, and should completely remove the flue soot. If not burning, can be re-started ignition; if burning, should be replaced, repaired burning member.
Concern three gas hot coal biomass oil fired hot+water boiler part of the gas hot water boiler is now in the streets everywhere are commonly used appliances, was warmly praised countless families. Since the advent of the diversification of gas hot water boilers, domestic hot water use headache solved the problem came to a great extent alleviate the difficulty of water, hot water is more difficult dilemma. Gas hot water boiler and hot water is able to provide us with such caring and thoughtful mainly due to the following three components. First, the ignition system. Gas hot water boiler function in that the ignition system ignites a mixture of air and fuel, its main components are: the ignition transformer, the ignition electrode, a high voltage electrical cable fire. A more secure electronic ignition system called ignition pulse, is widely used in many energy-saving gas boiler manufacturers. Because the time-saving convenience, simply by pressing a finger on it, and is safe, accidents do not occur by accident flameout occurs, once the stall condition occurs, the control system can close the solenoid valve, turn off the gas path. Second, the fuel system. Function boiler fuel gas water system is required to ensure that the fuel burner. The fuel oil burner system are: tubing and fittings, pumps, solenoid valves, nozzles, heavy oil preheater. The main burner gas hot water boiler with a filter, pressure regulator, a solenoid valve, and then firing solenoid valve, the fuel valve. Third, the electronic control system. Gas hot water boiler is the electronic control system command center and contact center system of the above, the main control element is a control box, for different burner with a different programmer, the programmer has common: LFL series, LAL series, LOA series, LGB series, the main difference is the time of each different program steps. The above is an important part of three gas hot water boiler. Gas hot water boiler manufacturer which is good when the next issue each family at the time of purchase will encounter, in fact, for this issue after reading this article may be an integral part of consumers based on the above three gas hot water boiler quality of the merits to determine whether it qualified as a selection criteria.
The szs series and wns series of oil and gas boilers produced by ZG boiler are the most widely used. In a big way, it can be widely used in heating, industrial steam and hot water supply, and the company has its own power station. Such as school heating, hotel bath hot water supply, food factory industrial steam supply. These two oil and gas boilers are all fast-assembling boilers with low capital investment and high degree of automation. Customers can choose according to their needs.
As a leader in the fast side condensing gas boiler, in recent years, provide a clean boiler to Beijing multiple office units, was well received. I units through the preliminary investigation and contrast, select fast boiler, it turns out, party fast product does have quite a good cleaning environmental performance, in line with the Beijing municipal government requirements for air pollution emissions, the use of very at ease. --customer feedback
