Heating and hot water daily is an important basis for maintaining the northern region of the normal operation of enterprises; for Legal Daily organs and units, the hot water residential hot wate boiler is one of the indispensable energy equipment. Currently, work is facing north Heating equipment and facilities aging, increase energy conservation and environmental protection requirements and other issues. Daily logistics-related legal person responsible for improving the overall level of heating units, and the response advocated by the national energy saving, plans to purchase energy-efficient heating boiler. Considering the increasingly stringent environmental policy, Legal Daily authorities decided to use natural gas as boiler fuel. Fast boiler for 20 years, specializing in the production brand boiler, which had been successfully assisted more than Beijing enterprises and institutions, to provide clean heating. The party technical consultant fast boiler based on actual usage Legal Daily units, providing commercial condensing units 99KW vertical 1 hot water boiler.
Boiler and specify different holes for residential hot wate boiler corrosion, the following is mainly to answer some specific questions, which mainly are: the boiler furnace in the manholes and hand holes, which specifically refers to what? In addition, for low and high temperature boiler corrosion, how should it be understood? These are the problems associated with the boiler, therefore, let's learn it. 1. boiler furnace in the manholes and hand holes in the boiler, manholes, which refers to access for people in the sewer, etc. in order to carry out maintenance work. And thus it can enter and leave Pai Road, boilers and water pipes and other such facilities. The hand hole, which can be considered to reduce the manhole. Mounting object thereof is to facilitate the installation, removal, cleaning and maintenance work, namely, to facilitate the work of some of the internal device boiler. These two, is basically the same in structure, and is a short tube section of blind plates. In diameter, hand hole is 150-200mm, and there DN150, DN250 both nominal diameter. The manhole is in the 1000mn above. 2. The low temperature low and high temperature corrosion of boiler corrosion boiler: heating surface in the rear of the boiler, such as an air preheater and economizer, etc., if present, and sulfuric acid, then combine with water vapor to form sulfuric acid vapor, together with the temperature is not high, the sulfuric acid vapor will condense on the heating surface, thus forming the sulfuric acid corrosion, that is, low temperature corrosion. And, it is mainly found in the air preheater, but again there will be the economizer. High-temperature corrosion of the boiler: the boiler at a high temperature state, an alkali metal sublimation, and the flue gas is reacted with sulfur trioxide to produce a composite sulfate, then, have a heating surface tubes and boiler wall, causing corrosion. So, these one corrosion, known as high-temperature corrosion. Also, pay attention to that which is generally repeated, if not promptly treated, then the wall will gradually thinning, the worst case, there will be burst pipes phenomenon.
Mainly use electric pipe washer, flat shovel, steel wire brush and hand hammer and other tools for mechanical descaling. This method is simple, low cost, but large labor intensity, poor scale removal effect, easy to damage the metal surface, only suitable for small residential hot wate boilers with small scale area and simple structure, which is convenient for mechanical tools to contact with scale. In recent years, due to the application of high pressure water gun for cleaning, the mechanical descaling of hydraulic flushing developed rapidly. The effect of this kind of high pressure hydraulic descaling has been greatly improved compared with the original mechanical tools, and it is more safe and convenient. But.
Dengzhou gas hot water residential hot wate boiler which company is good for the present, domestic gas hot water boiler supplier, depending on the load, each with their own strengths sample gas hot water boiler. Do not save people ask questions to determine whether the gas hot water boiler in question covers what professional standards. Generally in order to accurately choose suitable for use in our company's gas hot water boiler, such as the number of navigation which should know the following: First, the thermal efficiency of gas hot water boiler Second, gas hot water boiler began to contribute to the speed of three gas hot water boiler rated load four, a group of several types of navigation above the gas hot water boiler, gas hot water boiler is enough to get most of the usual non-compliance, and most certainly not up to thinking, from a number of navigation, can understand 1 gas hot water boiler set whether or not there is stability problem, obviously, gas hot water boiler election day, pick a most suitable to our company, the high cost of gas hot water boiler is the main thing.
