gas boiler manufacturers in india
The fuel of the oil-fired boiler manufacturers in india is the fuel (such as diesel oil, kerosene, etc.), the fuel of the gas-fired boiler is gas (such as natural gas, city gas, biogas, etc.), depending on what fuel the boiler burns, the equipment is called the burner. The boiler with gas burner is called gas boiler, the boiler with oil burner is called oil fired boiler. The difference between oil fired boiler and gas fired boiler is what fuel burners are used.
Fuel gas control step and the blowing process air volume of the total fuel gas steam boiler manufacturers in india steam boiler is achieved by adjusting a liquid coupling scoop blower. Organization fuel gas steam boiler combustion, is to make a, air pressure, air flow of secondary air with the good. Adjusting the amount of primary air should meet it carries the fuel into the furnace ignition of volatile oxygen required, and to maintain a certain speed, and without clogging the fuel discharge pipe of the jet having a certain rigidity. Primary air volume is too large and too small, the wind speed is too high and too low, should be avoided. In addition to adjusting the secondary air of combustion of the fuel should ensure that the oxygen demand, but must maintain a certain wind speed and primary air is mixed with the master time should have a strong stirring and mixing coke penetrate "the Gray" kinetic , which requires the case may be, each layer of the secondary air flow rate, in order to achieve stable combustion and flue gas excess oxygen appropriate destination. Fuel gas steam boiler, secondary air with what is better? Primary air volume air volume of the total share is called the primary air rate. A small air fraction, pulverized coal is heated to at least the heat required for the ignition point, fire faster, but the amount of primary air to satisfy the principle of combustion of volatiles. Secondary air mixed with the primary air time to the right. If it is mixed before ignition, means an increase in the amount of primary air, so that the ignition delay; hypoxia combustion secondary air if mixed will make late after ignition; if secondary air is mixed all at one position, since the secondary air temperature well below flame temperature, the flame temperature decreases, the combustion slows down, causing the fire. Therefore, the secondary air mixed with fuel should be based on the nature of the combustion zone as required timely sent, so that the combustion of oxygen, and will not reduce the flame temperature to ensure complete combustion and ignition stability. One or two wind speed with what is better? Fuel gas steam boiler once the wind speed is high, the fuel gas stream will catch fire in places far away from the burner, the ignition point postponed; once the wind speed is too low, it will cause a blocked ducts, and ignition point is too far forward, the burner will burn , but also easy to coke near the burner.
17.5MW YQL thermal oil heater for oil refining industryThe thermal oil heater is an essential equipment in oil refining industry, providing heat energy for rectification, hydrogenation, catalysis, gasification and other production processes. Dongfang Hualong Group is a large enterprise engaged in processing and sales of petroleum, main products include gasoline, diesel, propylene, liquefied gas, slurry oil, petroleum coke, petroleum machinery, etc. With the global green development trend, oil refining industry will adjust its industrial structure on a large scale. Dongfang Hualong Group seized the opportunity to accelerate transformation and upgrading and vigorously develop the circular economy. As an important part of production line, the thermal oil heater takes the lead in achieving equipment innovation. Hualong Group planned to purchase several energy saving and environmental friendly thermal oil heater to meet the needs of the production line. Quality has always been ZOZEN’s lifeline. In the pursuit of product quality, “never compromising to quality” has always been the principle that ZOZEN carries through, this kind of craftsmanship spirit successfully earned Dongfang Hualong Group's trust. The sales manager of ZOZEN provided the company 4 sets of 17.5 MW gas/oil-fired thermal oil heaters after learning about their actual demands. The thermal oil heater has wide adaptability of fuels, is suit for natural gas, coal gas, marsh gas, diesel, light oil, etc. The heat exchange surface adopts three-pass round coil tube structure, which features more sufficient heating surface. It is also equipped with an advanced burner to ensure the NOx emission below 30mg/m3. The waste heat boiler manufacturers in india, air pre-heater and economizer are installed on the tails of the thermal oil heaters to effectively improve thermal efficiency, which can reach above 98%.
Fangkuai Company has a fully-automatic PLC intelligent control system designed and developed by itself with complete intellectual property rights. It adopts a combination of mechatronic control equipment and a programmable logic controller (PLC). Take the advanced programmable logic controller (PLC) as the "central processing unit" of the control system. The control system is operated through the touch screen, which greatly improves the degree of automatic control and operation reliability of the boiler manufacturers in india, and the operation is simpler and more intuitive.
