wood based panel industry gas fire tube boiler

Burner fuel gas selected selection principles which fuel gas wood based panel industry fire tube 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.

New coal fire late, often appear off the fire bed fire, fire away from coal gate about 0.6 ~ 1.Om, burning furnace is not strong, high ash carbon content. For existing furnace arch structural problems, from improving fuel fire conditions, improve furnace temperature begin to transform the wood based panel industry fire tube boiler. After the furnace arch after the transformation, the people stove fuel from coal gate 0 · 3mRP fire, the fire bed combustion intense flame full of good, strong rotation. Since lowering the front arch, the arch extended, reduced to about 1 2 throat formed between the arch of the original pitch. Where the enhanced mixing flow disturbances, reorganized stream, enhanced combustion furnace, to effectively improve the temperature of the entire front region and the arch of the furnace, to reach 1400 degrees, the condition of the fuel to improve ignition. 2. The ignition point of coal in advance, the temperature of the furnace to improve the ash carbon content decreased. Smoke swirling mix and strengthen the separation of coke particles in the flue gas, so that it falls on the fire bed and the new layer further fuel burn. Flue gas also strong swirl in the flue gas CO, H2, CH4 and other combustible combustion gases, thereby improving the thermal efficiency of the boiler is more than 4%. But also improve the boiler output to meet the needs of the production of steam, reducing environmental pollution, expanding the scope to adapt varieties of coal.

The 5 ton natural gas wood based panel industry fire tube boiler used in the tea factory is the wns series oil and gas fire tube boiler. It has long been known that where a supply of steam is required for process work in any industry. In the tea industry, the 5 ton wns series natural gas steam boiler is used for heating the air required for the tea dryers and withering lofts. WNS series oil gas steam boiler is horizontal fire tube boiler. The boiler has steady temperature and high coefficient of heat transfer. And adopts specially designed combustion chamber for a better combustion efficiency. Advanced burner and proper sizing of furnace to minimize nitrogen oxides and other contaminants from forming during the combustion process. Electric control cabinet contains some buttons of burner, feed-water pump etc.

Recently, Heze City, Shandong Province issued the "implementation of Heze City plan" (the "Program"). "Plan" based on the optimal adjustment of the structure of industry, energy, transport and land use, in order to promote clean heating, public transferrin, enterprises mentioned standard provincial reconstruction focus, to further promote the autumn and winter air pollution in the comprehensive management of crucial action; fully completed in 2018 air quality improvement goals.

1, adjust and optimize the industrial structure, strictly control the "two high" industry capacity. And resolutely put an end to "scattered dirt" projects and has been banned "scattered dirt" off-site transfer business. Since October 1, 2018, thermal power, petrochemical, chemical, carbon, industrial boilers and cement and other industries, the implementation of air pollution emission limits in particular, to promote pollution control in key industries.

2, speed up the adjustment of energy structure, promoting clean efficient heating. The pooling of resources and vigorously promote the coal for governance, before the heating period in 2020 basically completed the life and motivations of heating coal for alternatives to achieve the task of clearing the loose coal. Is expected before the end of December 2018, the urban built-up areas out of 35 steam tons / hour coal-fired boilers, encourages other regions to advance out of 35 steam tons / hour coal-fired boilers. At the same time accelerating the transformation of low nitrogen gas boiler NOx emission after the transformation shall not exceed 50 mg / cubic meter.
