Gas oil-fired china 5 ton vertical fired boiler room ventilation system designed along with economic development, energy supply and demand changes in the relationship between environmental protection requirements increase, electricity and oil and natural gas in recent years, increasingly used gas oil-fired boiler. The gas oil-fired boiler room design related to people's life and property security of the country, but also can ensure the normal operation of critical boiler. In addition to the location of the boiler room and capacity to meet the relevant specifications, the design of the ventilation system which is also an important element in the design of the boiler room. However, due to the content of conventional ventilation and manual specification relates to small, there is no specific calculation method is given, designed to bring some difficulties. In this paper, problems in this area, combined with engineering experience of the author, make some analysis, calculation and discussion, put forward their views, for your reference. 1. Design Principles gas fuel boiler room ventilation system
With the development of economy and social progress and the improvement of people's awareness of environmental protection, coal-fired china 5 ton vertical fired boilers are gradually out of sight because of serious pollution. Instead, they are replaced by new types of environmental protection digital boilers, such as electric heating boilers, oil-fired boilers, gas-fired boilers, and so on. The operation of electric heating boilers is the most expensive, and gas-fired boilers need to be opened with gas pipelines. Then, if there is no natural gas pipeline and the operation cost of the boilers is expected to be low, only the fuel-fired boilers are heated through burners, and the fuel-fired boilers are heated through burners. Fuel atomization effect is good, fuel combustion is full, chimney can not see black smoke, so fuel-fired boiler green environmental protection, efficient and energy-saving.
Henan miss you Jujube Industry Development Co., Ltd. is mainly engaged in dates, nuts and other healthy food research and development, procurement, production and sales operations; jujube industry's first listed company. I miss you date industry is committed to providing health and hygiene products for people to date, in 2017, I miss you date industry decided to buy a few new clean and green, can provide high-quality steam china 5 ton vertical fired boiler steam. Carefully selected is determined in cooperation with the fast boiler, signed two separate 10 tons of steam condensing gas steam boiler (WNS10-1.25-Y.Q).
Burner fuel gas selected selection principles which fuel gas china 5 ton vertical fired boiler burners should be based on structural features and performance requirements of the boiler body, in conjunction with user conditions, making correct comparison, several general principles according to the following options: 1) according to user selection of used fuel type, liquid fuel kerosene, diesel oil, heavy oil, residual oil and waste oil, fuel gas city gas, natural gas, liquefied petroleum gas and biogas, fuel should have the necessary analysis of data used: ① kerosene, diesel should have heat and density. ② heavy oil, residual oil and the viscosity should, heat, moisture, flash point, mechanical impurities, ash, freezing point, density and the oil temperature. ③ should calorific gas, gas pressure and density. 2) to select the type burner nozzle atomization method or the gas burner and the furnace structure according to the performance of the boiler. 3) the 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. 4) adjusting the burner to a large extent, be able to adapt to changes in boiler load, to ensure complete stable combustion under different conditions. 5) fuel atomization less energy consumption, adjusting the wind resistance of the device to be small. 6) Effects of noise and smoke emission must comply with environmental standards, mainly emissions S02, CO and NOx must be lower than the predetermined country, should use low NOx burners and low noise. There are integral and split two 7) a burner assembly embodiment. 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. Simple 8) should be used in construction, reliable operation, easy to adjust and control the repair, easy to implement automatic control of the combustion process in the burner. 9) to deal with the burner brand, performance, price, and service life of comprehensive comparison. 10) In addition to the burner air pressure to overcome the resistance of the boiler body considered, but also to overcome the resistance and flue gas economizer system.
