bono steam boilers italy
Furnace explosion of the causes of ordinary gas boiler bono steam boilers italy gas burned in open flame and furnace process, if the following three conditions appear, it is easy to attack blast furnace accident. 1, open burning furnace, furnace residual gas content limit to reach the fire. 2, open incinerator, several points Eventually, the content of the furnace gas reaches the ignition limit, and then incinerated. 3, halfway flameout, fuel discharge series, spontaneous combustion of the fuel in the furnace temperature can change, so that the gas reaches the ignition limit of the content, and then incinerated. Forming flame halfway reasons are as follows: 1, gas is not supplied in succession. 2, during the adjustment, the valve opening degree increases or decreases suddenly. 3, lean fuel-rich flammability limit narrow. In order to avoid the onset of blasting incidents of burning fuel gas-fired boiler initiative and flame monitoring protection devices should be installed.
Because such gas boiler equipment belongs to gas energy, so the cost is relatively low, especially compared with coal-based boiler, in the cost have been reduced, has become among the many companies will attention to the point. Not only that, now the manufacturers, because in the production of technical improvements, so this device, you can have a system of automatic control, added safety protection devices, etc., so when during use, do not worry about the safety of one of the problem.
We all know that boiler scaling will bring a variety of problems to the boiler, such as reducing the service life of the boiler, increasing unsafe factors, making the boiler metal brittle, virtually increasing maintenance costs, and so on. So we have to regularly clean the boiler maintenance. So what are the methods and techniques of Fangkuai boiler descaling? The editor will list for you one by one: first, the artificial scale removal method, loosening the bolts on the boiler sewage outlet is generally common at both ends of the boiler horizontal tube, and we can see the scale on the inner wall of the boiler horizontal tube. Then use a small shovel and other tools (no hard requirements, can remove the scale from the boiler and The scale is scraped off or shoveled off, then rinsed the inner wall with water to flush out the waste, but this method is more energy-consuming to our production staff, the second is chemical scaling, This is a convenient and quick method of scale removal, chemical descaling process: clean water washing boiler cleaning agent, clean water rinsing passivation treatment; Before cleaning, we should disconnect other systems that have nothing to do with the boiler, connect the cleaning tank, the cleaning pump and the boiler into a cleaning closed loop; rinse once with clear water, wash out the large particles of dirt, and then put in the scale remover for circulation cleaning Wash and decontaminate, the process is usually 2 hours, then rinse again, clean up the residue, put in the passivation agent, maintain. These are two methods used at present. For boiler scales, we can pay attention to the treatment of boiler water at ordinary times, specifically lime soda softening method. In the water to be put into the boiler, we can use lime soda soften water. Reduce the minerals it covers, or put chemicals into the boiler to soften the water.
Recently, the Government Office of Hebei Province issued the "Hebei province coal investment projects coal alternative management approach", mainly to strengthen air pollution control, the implementation of total coal consumption control target. The new "management approach" referred to new construction, renovation, expansion project of coal, coal should carry out the same amount of reduction or substitution (hereinafter referred to as a substitute for coal). Coal substitute coal should be completed before the project goes into operation.
These measures apply to administrative areas in Hebei coal for direct consumption of fixed asset investment projects. It refers to the direct consumption of coal raw coal, washed coal, other coal washing, coal slurry, coal, coal and other raw materials or fuels production and processing or combustion, its coal facilities (facilities, tools) including boilers, furnaces , gasification, blast furnace and so on.
Coal alternative pathway includes the following four aspects: the elimination of backward production capacity, excess capacity and Yajian enterprises closed down, converting reduce coal consumption; the implementation of central heating, reduce coal consumption saving technological transformation or removal of equipment out of coal-fired boilers and other equipment coal consumption; use of renewable energy, natural gas, electricity and other clean energy alternative to coal consumption; the other to meet the requirements of coal consumption reduction approach. Replacement of coal coal project supervision and management, energy conservation authorities responsible for co-ordination at all levels.
