cheap environment friendly steam boiler
B, conventional gas boiler
The security measures mentioned above will need to invest a lot in research and development and manufacturing costs, many boiler manufacturers in order to save costs will reduce the number of security warnings probe, for users, this is a big risk.
Fangkuai Boiler has more than 200 after-sales service outlets across the country. Each after-sales service outlet is equipped with a professional boiler technical engineer, providing 24-hour emergency repair services, and has sufficient spare parts and wearing parts all year round, convenient. Customers change in time.
Where steam is used in the poultry feed process, a cheap environment friendly steam boiler is needed. A pellet mill with a capacity of 1.0 – 1.5 Tons Per Hour of pellets would require a steam generation plant capable of producing about 60-90 kg./hour of steam at 100 – 150 psi.
Low nitrogen gas boiler, as the name implies, refers to the use of natural gas as a fuel, and a series of measures, such that the major air pollutants - nitrogen oxide (referred to as NOx) emissions decreased down to within the range of emission standards. Nitrogen gas boiler low NOx generation type can be divided into thermal NOx (ThermalNOx), flash type NOx (PromptNOx) and the fuel type NOx (FuelNOx). 1, since the amount of nitrogen gas is lower, and therefore, the fuel NOx is not a major type of control. 2, thermal NOx refers to NOx combustion air at a high temperature oxidation of N2. On the thermal NOx formation mechanism commonly used in the Czech Popovich channel mechanism: When the temperature is lower than 1500 ℃, the heat generation amount of NOx is small; Above 1500 ℃, the temperature is increased 100 ℃, the reaction rate will increase 6 to 7 times. In the actual combustion process, since the temperature distribution in the combustion chamber is not uniform, if there is a local high-temperature region, the NOx generated in these areas will be more, it may be the entire NOx formation in the combustion chamber plays a key role. 3, in the case of prompt NOx in the combustion of hydrocarbon fuel and fuel-rich reaction zone quickly generate NOx. Various factors alone changes in the actual combustion process, a number of parameters are in constant flux, even a simple combustion of gaseous fuel, the fuel and air should be subjected to mixing, combustion fumes, until leaving the furnace. The degree of mixing temperature of the furnace fuel and air, flue gases in the furnace and residence time of these parameters have a great effect on NOx emissions are in constantly changing.
