How to improve the thermal efficiency of gas steam energy saving diesel boiler steam boiler to improve the thermal efficiency of gas is a problem many users are taken, I believe this issue is the direction of each used in the production of various types of gas steam boiler manufacturers have been in the study. Many users at the time of the gas-steam oven operates, often in the actual production process, we found some new problems, but all the problems, the most vexing is the high temperature exhaust gas steam boilers, thermal efficiency than low phenomenon that a serious impact on our work, then how should we do to improve the thermal efficiency of it? need to know this is the best way to meet the low-temperature properties of gas and steam comes as synthetic gas steam. However, the vast majority of synthetic gas and steam biphenyls, benzene derivatives of both components of the complex, or a vapor of volatiles has strong carcinogenicity, it is strongly recommended that the client select the type of mineral oil vapor product gas. Second, gas and steam products to meet the low temperature performance process, but also have a relatively high flash point required. In general, gas steam engineers suggest, low temperature gas steam flash point not lower than the opening 200 ℃. After a professional manufacturer of continuous research and improvement of its equipment, in order to improve its thermal efficiency was found to be increased tail gas steam boiler heating surface of, say, air preheater and economizer. But when organic heat carrier furnace return temperature is high, you can not set the economizer, air preheater can only be set to alleviate the situation. So if no gas steam boiler and other heating systems for low temperature heat exchanger, then the only way to improve the energy efficiency is adding air preheater. After adding air preheater can be a corresponding increase in gas flow rate of steam, gas steam boiler in order to ensure safe, reliable and stable work, the thermal efficiency of gas-steam boiler plant will be a corresponding with the increase.
Boiler burner selection techniques to select the type of burner nozzle atomization or gas burner and furnace energy saving diesel boiler performance according to the structure, which is the most important point. Today we take a closer look. Burner output should match the rated output of the boiler, choose a good shape of the flame, such as length and diameter so as to adapt the furnace structure. The required combustion air is supplied from the root flare fuel gas and air or oil mist uniformly mixed rapidly, to ensure complete combustion. The rated output of the boiler and boiler efficiency is determined, the fuel consumption is calculated, and then selected according to power a single burner arranged to determine the number of burners. Increase the number of burners, in favor of the atomization quality assurance wind oil mix, but too many, and not easy to operation and maintenance, will give burner arrangement difficult. Adjusting the burner to a large extent, be able to adapt to changes in boiler load, to ensure complete stable combustion under different conditions. Fuel atomization less energy consumption, adjusting the wind resistance of the device to be small. Effects of smoke and noise emissions must comply with environmental standards, the main emissions must be below national requirements, should use low-noise and low burner. There are integral and split two ways boiler burner assembly. I.e. monolithic burner body, the burner and a combustion air blower system (including an oil pump, a solenoid valve, a servo motor or the like) into one; split i.e. burner body (comprising a combustion head, oil or gas systems), fans and combustion burner control system (including the control box, fan thermal relay, AC contactor, etc.) are each independent three-part system, according to the specific requirements of the boiler and user choice. We should use a simple structure, reliable operation, easy to adjust and control the repair, easy to implement automatic control of the combustion process in the burner. Respond burner brand, performance, price, and service life of comprehensive comparison. In addition to the burner air pressure to be considered to overcome the resistance of the outer boiler, economizer and also to overcome the resistance of the flue gas system.
Burner and flue installation and electrical installation and the fuel supply system of the burner 1, burner 1) before installation read "burner manual", according to the installation requirements. 2) Burner mounting flange, the middle requirements, to ensure the burner to the energy saving diesel boiler flue gas does not leak at the interface. 2, the installation of fuel supply system (see schematic) Note: To prevent a fire caused by generation of static electricity in the fuel tank, the tank should have a good grounding. 1) supply system tank top tank top-feed system suction recommended distance between the back plane and the tubing inside diameter of the oil pump axis, the total length of the suction pipe Hm, m, no greater than DL6-34DL40-75DL100-250Di = 10mmDi = 14mmDi = 16mm0.51.03030401.535452.03535452.540503.0404050 Notes: (1) when there is an elbow or valve on the suction pipe, each of the length of the suction pipe to be minus 0.25m. (2) Di recommended internal diameter suction pipe and return pipe. 2) the distance between the bottom of the tank bottom of the tank supply system supply system pipe inner diameter recommended oil pump axis and a plane, the total length of the suction pipe Hm, m, no greater than DL6-34DL40-75DL100-250Di = 10mmDi = 14mmDi = 16mm1.03030401.535452.03535452.540503.04040504.045 Notes: (1) when there is an elbow or valve on the suction pipe, each of the length of the suction pipe to be minus 0.25m. (2) Di recommended internal diameter suction pipe and return pipe. 3, gas pipe installation requirements Burner gas line itself has been connected, the intake port, the intake pipe bends should be minimized and good sealing performance requirements, to prevent leakage. (Iv) a chimney installation, to prevent leakage, the leakage of smoke, to prevent smoke inhalation chamber. 2, a vertical mounting, a right angle bend bends should be avoided. 3, the top of the chimney must be water-resistant measures. (E) mounting a power switch with electrical connection box 1, the power switch should be considered easy to operate, away from heat, fixation, meet the design requirements. 2, the use of 220V (380V), 50HZ power source, and a ground line. 3, voltage instability in the region use, should be safe regulators. Or affect the normal operation of the combustion engine. 4, the power cord to the electrical box must be connected in strict accordance with the requirements, otherwise, there will be dangerous!
