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.
Ningde gas oil horizontal 2019 hot selling wns 10 ton diesel industrial steam boiler steam boiler in the process of selecting our chosen medium, many questions will be met. Here, we have to talk about with small series. Main steam boiler steam boiler cost expenses, and costs burner, random (circulation pump, control panel, valves) the cost thereof. Determine the cost of steam boiler reason, the main cause for indulgence: product, respectively, factories, skills development, testing, planning, selection and other steel products. Among them, the best should pay attention to the following reasons: ⑴ strength of the manufacturer's plant productivity, it is likely to decide the quality of the product. Because all a productive company, excluding occupy a larger market share, release the right amount of experience. Han, secondly, the power of professional design products. Planning strength size for product quality implications are enormous. A direct impact on the product in the future with stability, energy efficiency, safety, and good operating standards. ② selection of quality metrics steel, steel is the core product development. Professional authoritative standard steel steam boiler is to ensure effective sealing of the firm. There are some small factories with substandard or use non-standard steel products will result in steam boilers, poor stability, high operating costs, in addition there is a certain security risk for customers, when even save enough to get the money, but worth the candle. 3 Development of an automatic steam boiler standards development process, cutting, plate bending, cutting, should pay attention to the best skills. These three techniques, the comparison must be to, manual control, the use of automatic development, highlights prominent relatively common. Because ISO production, with advanced precision, minimal mistakes. This is also the key reason for the large steam boiler products product, far better than small products. Because it, the results of research, planning and more closer connection strength, together with good access to authoritative standard setting. d detection criteria many factories in China, a lot of time there will be no steam boiler products through rigorous factory part of the evaluation assessment. Pressure to complete, even if the professional products. This is certainly a very fulfilling responsibilities. Professional detection criterion must probably comprising: a pressure test, the test inert gas, welding gap detection, detection of the seal, and the test run. Can be neglected, balanced. The only way to ensure that customers have a grasp of professional products to customers in the future when used to eliminate non-compliant products have generated, the impact to the customer's daily production and business activities. ⑸ quality after-sales 60% of small factories, there will be no after-sales. After-sales support are entrusted proxy to master. However, 60% of agency staff, there are few professional standards of the strength of the team. After generating non-compliance, it will have dragged on, or use the results often can not be solved. To sum up, that is, the cost of a steam boiler, the influence of reason. Normal in terms of strength, good steam boiler product cost, plus the steam boiler burner, the basic, 700KW, 10 million and decided.
Subsequently, the delegation visited the company's boiler cleaning laboratory, technicians demonstrated to the delegation of the company's latest product boiler operation, and use of DCS control system in the laboratory trace data. Mr. Liu to our boiler products to achieve nitrogen oxide (referred to as NOx) emissions below 18 mg or less, is widely used in Beijing APEC venue, the Central Authority and other countries prefix institutions and other international occasions expressed a high degree of praise and encourage.
Steam boiler fuel gas composition changes so the General Assembly cause flameout: fuel gas 2019 hot selling wns 10 ton diesel industrial steam boiler pressure off the fire caused by a sudden rise, the solenoid valve malfunction the gas supply interruption, the gas composition has changed so much moisture content is too high and so on. Blower, fan failure, the load is too low furnace pressure is too large excessive leakage and other excessive wind, so that the furnace temperature is too low can also cause steam boiler fuel flame. Causes fuel steam boiler flameout are: oil pump failure, the oil surface is exposed inhalation tube, clogging of the oil filter or oil supply pipe, a solenoid valve malfunction or misoperation caused by oil running intermittently. During transport the fuel with steam by heating water; inappropriate position inhalation tube with the pumping of water; improper contaminated oil floating on the water; poor dewatering tank drain plug such that the fuel with water.
