food natural gas atmospheric boiler manufacturers

Coal to natural gas operations bunch of factors that vertical pressure steam food atmospheric boiler manufacturers energy consumption indicators of the country are carried out in a big way, the choice of vertical steam boiler, to a large extent minus the pollution of powder, together with nitrogen oxides and other dangerous gases the press has been discharged. Energy consumption indicators is an important rule to measure vertical steam boiler, to discuss the next bunch of factors under pressure vertical steam boiler energy consumption indicators. By analyzing the relevant departments, vertical steam boiler heat loss occurs mainly includes two aspects: the proportion of non-standard sufficient combustion air with exhaust heat loss. Weaken the heat loss can be retrofitted in the vertical steam boiler chimney terminal latent heat of re-use form, or in the selection of better boiler system FGR. Combustion air ratio is not sufficiently decomposed inappropriate criteria: ordinary vertical ejector-type steam boiler burner based, air-fuel ratio can not be formed in the active mobilization. More vertical steam boiler based on a mechanical blower burner, air-fuel ratio due to the following standards several factors: air-fuel ratio standard comprises two situations: when oxygen is excessive, the excess will be an infinite cryogenic air by heat conduction, caused by rising energy vertical steam boilers, low energy consumption vertical steam boiler index; when there is insufficient oxygen, there will not be sufficient to ignite the situation, leading to low energy consumption indicators vertical steam boiler.

Coal-fired food atmospheric boiler manufacturerss to gas boilers benefits and precautions With the rapid development of national energy-saving environmental protection, the traditional coal-fired boiler can not meet the needs of the times. Therefore, the coal-fired boiler biomass boiler or gas boiler has become in many boiler user's choice. Before the transformation, to understand the difference between .1 and gas boiler fired boiler. Circulating fluidized bed combustion boiler fired by coal crushing device fluidized combustion process, the coal by crushing device percutaneously into the bunker through a the spreading coal coal injecting air into the furnace; circulating ash by heating, fluidized combustion process. When the coal into a gas fuel is injected directly into the combustor for combustion. 2. Combustion of Coal is mainly composed of C, H, O, N, S, ash and moisture and other elements. Generated when coal SO2, SO3, NOx ash and moisture, and SO2, SO3, NOx from flue gas emitted into the atmosphere, pollute the environment and cause harm to humans. The main components of the exhaust gas and coke are CO and H2. The main produce CO2 and H2 post-combustion, much lower than coal-fired boiler SO2, SO3 and NOX emissions. 3. Ventilation pressurized combustion coal combustion boiler used in a combustion mode. The bottom of the combustion process through the induced draft fan with fan and completed. In the combustion of coal, it requires a lot of air. Gas under a slight positive pressure in the boiler or burner slightly negative pressure, which requires less airflow. Burner air may be pre-mixed with natural gas. 4. coal boiler control reasons, material thickness, amount of wind, the wind volume, wind and other than coal, coal-fired boiler is difficult to automatically adjust the operating parameters of the boiler according to the load. However, fewer factors gas boiler, the burner valve can be adjusted according to the size of the load, easy to implement automatic control. Coal-fired boiler to a gas boiler Notes: Main results are as follows: (1) small boiler, the coal-fired boiler to a gas boiler, i.e. the negative pressure of combustion from the original to the current combustion slight positive pressure, and must pay attention to the furnace wall structure sealing problems. Closely related (2) selection and arrangement of the burner and furnace, the degree of filling of the flame in the furnace is preferably not formed dead air, to avoid the interference of adjacent flame burners, to avoid interference from adjacent burner flame. Unburned gas - air mixture should not be in contact with a heated surface, in order to avoid incomplete combustion. Gas combustion. Gas burner arrangement disposed conduit and ducts should be considered reasonable gas pipe and duct arrangement, ease of operation, inspection and maintenance. (3) the transformation of coal-fired boilers is mechanized layered gas boiler should be removed before the arch and the arch, and the bottom heating surface increases, in place of the grate, the grate to prevent overheating. Gas Velocity (4) on heat transfer surface of the fly ash is not restricted abrasion conditions, convection heating surface heat transfer coefficient is increased, increasing the pressure in the boiler where H is unduly increased. Boiler erosion surface. At this time, the capacity of the boiler should be noted that the steam separator to ensure the quality of the steam.

The beverage plant needs steam in its beverage degassing ,sterilization, and packaging process. 3 ton steam requirement per hour came from beverage plant steam requirements in all process. Then, why there must be WNS series, any other choice here? WNS series steam capacity is from 2 ton to 10 ton, more suitable for lower capacity steam food atmospheric boiler manufacturers. Of course, we also have SZS series which capacity is from 4 ton to 30 ton. To larger steam requirements, industrial gas oil fired power plant boiler is also available. If you want to use other gas fuels like lpg gas, bio-gas or liquid fuels like diesel oil, heavy oil, light oil, our WNS series steam boiler also can burn them. But, like our advanced engineer said before, each boiler is specialized for one designated fuel, this WNS series 3 ton steam boiler is manufactured to burn natural gas. Although it can burn other fuels, it can reach highest thermal efficiency when burning designated fuel natural gas.

Recently, we learned, Zhangbei County, Hebei Province to speed up the transformation of low-nitrogen combustion, gas-fired, Zhangbei County Environmental Protection Agency issued the "Notice on nitrogen oxide gas food atmospheric boiler manufacturers governance", the transformation of the way around the gas boiler, the transformation of technology formalities to conduct a comprehensive explanation of propaganda, mobilization of Zhangbei above a certain size gas boiler units to actively participate in low-nitrogen transformation.

In order to ensure the smooth progress of work, the EPA developed a grasp of leadership, and a series of regular briefings on the system, arrange for the transformation of real-time tracking progress, personally led by the leaders in charge of the transformation of the construction-site supervision, to solve various problems during installation accelerate the transformation progress of the project. To date, more than 10 tons of steam Zhangbei natural gas boilers have been completed the transformation and detection of nitrogen oxide emissions, emission concentration all the stabilizing reached 30mg / m³ or less, over-done.

To protect the subsequent reconstruction work in depth, Zhangbei County township organization, the relevant units of the county with a comprehensive Mo Pai, gas-fired, gas-fired boilers for each specific model boiler unit, whether used and other basic information has been verified, the establishment improve the work ledger; to ensure that the base number is accurate, targeted work, Zhangbei arrange strengthen docking with the gas company, promptly verify the perfect new gas boiler archives, ensure the follow-up task of transformation clear, exhaustive renovation project. At the same time, combined with the actual development of the Zhangbei gas boiler compliance programs to lay a solid foundation for the comprehensive promotion of this work next year.
