low nox emission 3 pass gas fired combi Boiler
3 ton oil gas low nox emission 3 pass fired combi boiler for concrete mixing plant
The product of this project is the CBM wns series oil and gas steam boiler with a boiler capacity of 3 tons. The boiler is used in a building material factory in Russia to provide steam for concrete production.
Dongguan City, Guangdong Province in phasing out coal-fired low nox emission 3 pass fired combi boilers to replace the environmental transformation, biomass boilers in industries packaging, leather, clothing, textile and other widely used. However, biomass boilers still present drawbacks: If insufficient biomass combustion, typically generate a lot of dust, nitrogen oxides and other pollutants, improving PM2.5 concentration, air quality.
Dongguan City Atmospheric Office official said that since the Dongguan started Blue Sky Battle since, the city ton output capacity the courage to decisively eliminate those high pollution and high emissions industries and enterprises, won the majority of the masses of people, as well as many businesses family support; many enterprises to actively upgrade and elimination of outdated equipment and production capacity. In the eco-friendly background, out of high pollution equipment is the trend.
Transformation and upgrading of enterprises demand, government support policies have, inside and outside the echo, Dongguan out of biomass boilers into the fast lane. As of January 10, a biomass boiler out of the task of the city within 31 town street in Shilong, South City, the nave, Ma Yong, Hou Jie, stream, Feng Gang, Xie Gang, Chang Ping, Shek Pai, Chashan 11 Towns in the completion of the task of eliminating all living matter within the jurisdiction of the boiler. In addition, Long, Qi Shi, Tangxia, Sha Tin Kau five towns out of the completion of more than 90%, the remaining 15 Towns also have the confidence out of the task in the year 2019.
While out of the biomass boiler, Dongguan City, accelerate the pace of construction of gas pipeline to provide clean energy for the needs of the enterprise.
Atmospheric Office official admits:. "A few years ago, the city lags behind the construction of the gas pipeline, laying of pipe network coverage area of a small number of enterprises in the coal phase-out of high-polluting fuels, the use of biomass boilers as an interim energy supply equipment, there are also often allowed to change the fuel business, steal burning coal. "but now, due to the environmental protection departments to actively coordinate the town street, village (community), industrial areas, and vigorously promote the construction of natural gas pipeline, starting from the source to provide clean energy for businesses, stealing burn the behavior of coal is greatly reduced.
Over the past year, the city has a new natural gas pipeline 256.6 kilometers, 530 companies have security using natural gas. The city urban management department based on the actual distribution of useful gas needs of enterprises to develop business for the city's more than 600 natural gas pipeline construction plan and coordinate the new Austrian, Xinghua, often positive and three gas pipeline company to carry out construction work to ensure that the natural gas pipeline construction project smoothly, so that more companies access to clean energy as soon as possible.
According to statistics, date, Dongguan City gas pipeline or central heating station accessible area of 660 biomass boilers, has eliminated 572 units, 41 enterprises have to apply for the boiler out of subsidies.
1. oil and gas steam low nox emission 3 pass fired combi boiler system
A complete gas boiler system mainly includes the boiler body, burner, control system and other auxiliary structures
Temperature protection device during the fuel steam low nox emission 3 pass fired combi boiler over temperature to regulate protective effect of temperature protection is an important procedure fuel steam boiler safe operation is particularly important for the regulation and protection of the boiler temperature of the fuel vapor; at the same time to regulate in the fuel steam boiler overtemperature Protective effects. Conventional boiler temperature protection means is a bimetallic temperature controller. Flame protection: prevent explosion of the furnace, steam boiler fuel flame protection means must be provided, is a function of combustion (including ignition, combustion or misfires when halfway off, typically within five seconds reignition monitoring the furnace, a second the run off into the oil (gas) solenoid valve, and turns on and audible alarm signal, when the blower continues to operate, the residual gas was purged of combustible furnace, after 20 to 30 seconds purge, automatically cut off and various auxiliary blowers supply the boiler operation stops. role is to monitor the flame signal the presence of a flame or an interrupt control apparatus mainly using a photomultiplier tube, a photovoltaic cell and photosensitive resistance, they have an infrared type or ultraviolet type a photoelectric conversion element, the working principle of the light converted to the corresponding strength of the radiation strength of current and the linear output state, sometimes weak induction current, through amplification, in order to have an effect on the controller.
