oil and gas hot water boiler in korea

In food factories, heat source equipment is essential. In the process of food processing, the process of disinfection and ripening of raw materials is inseparable from the application of boilers. The oil and gas boilers produced by ZG boiler can provide industrial steam or hot water for food processing to transfer heat.

Recently, Shaoxing, Zhejiang Province, the municipal government issued "on the issuance of Shaoxing new coastal air quality standards carry special action program" (the "Notice"). "Notification" is mentioned: a ban on new biomass boilers, nine companies continued to promote the transformation of low-nitrogen gas boiler.

4. The built-up area to carry out bulk coal campaigns to strengthen the use of bulk coal production and life behavior of businesses and residents a comprehensive investigation and persuasion, to ban briquette production and sales, and increase legal coal quality supervision, strict penalties for substandard coal burning behavior.

2. carry out an intensive investigation, the establishment of various types of industrial furnaces inventory management, development of industrial furnaces depth remediation, complete elimination of the task assigned by the city. Strictly implement the relevant emissions regulations, can not reach the relevant requirements, the implementation of cut-off regulation.

3. Conduct brick kiln depth remediation, strict implementation of emission standards, enhance on-site inspection of law enforcement, monitoring, focus on examination of the "three simultaneous" implementation and pollutant emissions, on-site monitoring of the discharge port sulfur dioxide, nitrogen oxides, particulate matter and other pollutants .

In general, there are many factors that affect the price of the boiler. ZG boiler 10 tons oil and gas water tube boiler is a very popular boiler in many industries such as food factories, paper mills, hotels, planting greenhouses. In many industries, the use of steam boilers is the equipment that is required for many processes. Heating boilers are also a demanding device. After statistics, the 10 ton boiler can adapt to many environments. The price of 10 tons of oil and gas boilers is a concern of many customers.

Improve the thermal efficiency of the process wns gas boiler, oil-fired boiler which chemical incomplete combustion heat loss and mechanical incomplete combustion heat loss. Because almost no ash after combustion of the gas boiler, solid and liquid fuels without mechanical incomplete combustion, there is no need to consider the mechanical incomplete combustion of the gas boiler heat loss. In all heat losses, heat losses have tremendous proportions, when the high thermal efficiency of boilers, heat losses so the total loss of the main heat losses of fuel gas-fired boiler flue gas heat loss is the exhaust gas temperature and For air excess factor. When the exhaust gas temperature decreases, high thermal efficiency can be obtained, for example, a conventional three-pass steam boiler, furnace used in the past straight and smooth smoke tube, must increase the heating surface is arranged to make the exhaust gas to an acceptable degree, the theoretical discharge around the smoke heat loss. Potshell causing significantly increased diameter, wall thickness increased, greatly increased metal consumption, thus further reducing the exhaust gas temperature should be greatly restricted. From the aspect of heat transfer is not only now consider only the heated area, the use of new technology enables heat transfer performance significantly increased, the difference between the heat transfer overcomes the disadvantages of the past performance of the boiler, so that the exhaust gas temperature decreases, the structure is more compact. Center back boiler combustion boiler is preferably small foreign structure, although the two-pass boiler, the heated area is small, but the use of the turbulator charming, the purpose of enhancing the turbulence of the flue gas, disrupt laminar flow boundary wall, reducing the thermal resistance, increasing the heat transfer coefficient, a smaller heating area to achieve the same high thermal efficiency. Lower exhaust gas temperature limit in theory, the exhaust gas temperature can be reduced to very low or even close to the ambient temperature, for maximum thermal efficiency. However, in practice, due to the reduction of the exhaust gas temperature, low temperature corrosion will cause, therefore, the exhaust gas temperature can drop too low, in order to ensure that the wall temperature is higher than the main boiler heating surface flue gas dew point temperature. Therefore, low-temperature corrosion has become a major obstacle to reduce exhaust gas temperature and improve the thermal efficiency of the boiler. Tail auxiliary heating surface increases, further reducing the exhaust gas temperature, fuel gas wns improve thermal efficiency of the boiler as the oil, gas fuel burn easily wns type gas boiler air preheater generally not disposed. The economizer means is a common energy, which can be recycled flue gas was able to effectively reduce exhaust gas temperature. Separation type condensing gas boiler is out of the main boiler heating surface, the installation of the condensing heat exchanger. In one aspect of the flue gas absorption can significantly reduce the smoke temperature, reducing heat losses, on the one hand the absorption of part of the potential condensing water vapor released, increasing the effective use of heat of the fuel. Ash cleaning, to ensure that the heating surface of the scale wns boiler thermal efficiency of the boiler, the presence of soot fouling and heat transfer resistance increases, reducing the heat transfer effect. The thermal conductivity of the scale and soot is almost of the same order of magnitude, with the increase in scale, soot, the exhaust gas temperature rapidly increases, the thermal efficiency is significantly decreased. So, keep the boiler heating surface inside and outside clean, efficient heat transfer, thermal efficiency and to ensure the safe and economic operation of boilers, boiler fuel gas-fired boiler ash cleaning is required.
