gas fired hot water boiler supplier in thoothukudi

In mid-June this year, Hebei Province issued a notice regarding the development of gas-fired boiler nitrogen oxides (referred to as NOx) governance, in order to further deepen the boiler pollution control, reduction of nitrogen oxide emissions, improving air quality, will gradually nitrogen oxides exceeded boiler discharged for investigation and control work, high nitrogen oxide emissions from the original (150mg / Nm3 or above) is reduced to 30mg / Nm3. City, Hebei Province is located in the Yili Dairy Co., Ltd. to respond positively to governance EPA gas boiler NOx reduction, and led the way, three of the company's existing 15 steam tons / hour (t / h) gas steam boilers for low-nitrogen emissions transformation.

First, the advantage of low nitrogen fuel gas condensing boilers due to the low nitrogen fuel gas condensing boiler is more environmentally friendly, low nitrogen, low in nitrogen transformation, select the replacement condensing boiler has become a trend, we take a look at low condensing nitrogen gas boiler fuel What are the advantages: 1, high efficiency fuel gas condensing boiler thermal efficiency than ordinary fuel gas boiler 20 to 30%, the boiler efficiency heat of condensation water up to 109%. 2, the fuel gas condensing boiler flue gas temperature is low condensing boiler exhaust temperature is low, the exhaust gas temperature is less than 60 ℃. 3, water temperature adjustable range of large oil or gas condensing boiler owned the world's most advanced, highest quality water temperature control system and unique structure and combustion. Adjustable water temperature: 30 ℃ ~ 95 ℃. 4, more environmentally friendly fuel gas condensing boiler nitrogen oxide (NOx) emissions of only 30 ppm or, below the European standard grade 5 56ppm. Carbon monoxide emissions significantly lower than the general emission standards for boilers. Due to the high combustion efficiency, much slower than that of carbon dioxide generated gas boiler. Operating noise of less than 40 dB. 5, safer fuel gas condensing boiler with forced circulation, indoor air may not burn (Normal room air combustion boiler must, for safety need to increase smoke alarm system). 6, install the small size of the fuel gas condensing boiler covers an area smaller than a conventional boiler, saving boiler room area. 7, district heating control system provides complete control of district heating systems, intelligent control of all major equipment in the heating network, rational use of the entire district heating, more energy-efficient. 8, the fuel gas condensing boiler technology unique condensing fuel gas condensing boiler unique condensing technology, maximize the use of the heat produced by the combustion, the use of advanced technology sufficiently mixed fuel and air, combustion of the fuel supplied to the boiler adequate power, while the heat in the flue gas to maximize the recovery of exports. Exhaust gas temperature can be reduced to below 60 ℃ (usually 40 ℃). 9, the latest concept of modular design using the latest condensing fired hot water boiler supplier in thoothukudi concept of modular design, according to the actual needs of users, providing various types of fuel gas-fired condensing boiler models of different specifications.

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.
