Low Emission Stainless Coating Gas Fired Hot Water Boiler

Biomass low emission stainless coating fired hot water boiler for heating company fueled with the biomass grain fuel,which is abandoned as agricultural straw waste instead of the fossil fuel.this fuel is easy to get and extensive sources, the fuel costs are lower than the original coal, oil and gas, which is a great way to reduce investment cost for biomass boiler used enterprises.

There are reasons for chemical plant boiler water wall high temperature corrosion which causes of high temperature corrosion chemical plant boiler water wall What are the causes of high temperature corrosion chemical plant boiler water wall which 1, raw coal sulfur compounds according to relevant statistics analysis shows that coal inorganic sulfide occurrence sulfur-based, accounting for 60% to 70% of the total sulfur content, the remaining 30% to 40% is organic sulfur. Occurrence majority of the inorganic sulfur in the form of pyrite, sulfate, only a small fraction of inorganic sulfur content of the sulfur in coal measurement results shown in Table 2. The morphology of pyrite by more slagging and corrosion of boiler serious implications, and therefore subject to people's attention in the course of practice, but often ignore the corrosive effect of sulfate on the Wall. Thus, in practice it is necessary to form during combustion of sulfur in coal is measured. 2, the chemical analysis of coal coal boiler is 50% to 50% of anthracite and bituminous coal, coal testing seen from the data of research institutions, the volatile coal employed in the chemical, crystalline water, CO2 and other non-combustible or higher levels of flame-retardant component, low CH4, H2 and other combustibles content, higher temperature requirements volatile release, slow release, long time to burn coal, high ash content of the combustion, appears likely to cause the waterwall reducing component. 3, the size of the inscribed circle boiler chemical analysis boiler designed to be used with pre-mixed coal, to achieve the purpose of enhancing combustion, therefore the design Tangentially Fired large, will cause a large inscribed circle after the formation of the combustion of coal pulverized coal, gas and other substances appear high temperature corrosion. Related experimental results also shows that, when the circle diameter of the boiler in the range of 8 ~ 8.3m, after leaving a nozzle air flow deflection under the action of mixing the secondary air mixed gas stream is significantly down and floating inscribed circle than the other Big. 4, when the airflow and dual channel burner boiler design analysis consider using bituminous coal and anthracite mixed, the use of a secondary higher wind speed, a wind speed is low, the size of each of 43.5m / s, 22.5m / s, a , the second big difference wind speed caused the jet rigid significantly different. Due to the impact of differences in conditions and the gas stream upstream sides of adjacent angles of qi, when a secondary stream ejected from the burner, the air flow occurs toward the back direction of the flame to the water wall offset time smaller jet velocity Merry occurs a more obvious than the secondary airflow offset such that once the separation between the secondary air flow significantly. By using correlation analysis tests like long streamers understood, a significant portion of the air flow downstream of the boiler walls against movement, so this part of the secondary air flow departing from the airflow direction, coal and other combustible materials in the combustion under insufficient oxygen supply, a certain amount reducing gas component. Because the use of the two-channel burner design, a secondary air flow separation phenomenon of increasing offset, to some extent, when a relatively strong reflux in the boiler, the flue gas, the better the effect of reflux, the more obvious the effect of fuel combustion, but it can also lead to increased attenuation of a romantic reflux stronger. Dual-channel design such that the outlet area of ​​the burner than traditional single channel many large exit area, but also makes the primary air flow greatly reduced exit velocity. The foregoing analysis, and a dual channel design, the secondary air flow speed difference, so that a significantly reduced stiffness airflow, airflow offset serious, prone to high temperature corrosion in the waterwall. Analysis of coal pulverizing system thickness 2.5 coal boiler is based on coal and coal burning coal designed, when using low-quality coal, pulverizing system load increases, reducing the separation effect, resulting in coal particle size increases, the thickness of the pulverized coal has a significant effect on high temperature corrosion of the boiler, coal particles increase when the torch burning in a boiler long prone to decrease the effect of the combustion of pulverized coal, coarse coal particles are not completely combusted powder boiler water wall in the vicinity of the bond, so that high-temperature corrosion intensified.

Qiaqia Food adhere to "create quality products, spread happiness taste" for the mission, after two years of concentrated operations, increasingly rich product line gradually improve production management system, and improve product awareness, economic and social benefits increase year by year. 2018, Qiaqia plant selector fast fuel gas steam condensing boiler for the production of overseas projects. Fast condensing side fuel gas steam boiler with a blue appearance color used, overall nice; also has energy saving, small footprint, easy operation, long life and other advantages. For the convenience of local plant operations, specifically on the fast side of the operation panel adds English and the local language (s) in the production of boiler Shihai contact contact order.

Electric boilers and power consumption advantages and what about the gas boiler: the boiler, it contains content knowledge, there are many, and, associated with difficult problems, but also have a lot, so below, you may wish to adopt a question answer this form, answering questions for everyone, and thus, there is a good learning effect, this also allows us to own, from a new harvest, and to make progress and development. 1.70MW and boiler 100t / h boiler, which is the same as you? This problem, in the boiler manufacturer boiler box appears, is not difficult to answer, so they give specific answers, is: 70MW boiler 100t / h boiler, two boilers, if, from a conceptual point of view, then then, they are the same, because the total for the heat, is the same. However, for the type of boiler, there may not be the same. The former, there may be low emission stainless coating fired hot water boiler, while the latter, there may be a steam boiler.
