Gas steam boiler Gas steam boiler faults and fix problems economizer heat what is the reason? Acoustic cleaners using main function is used to remove fouling the heating surface of each gas-fired boiler, has the advantage of traditional mechanical cleaning, sootblowing steam and ash ball, etc. can not be compared, in the electric power, petrochemical, and other fIELD used widely, part of the solution superheater boiler system, the new non-contact heating surface cleaning method of cleaning economizer, an air preheater and a waste heat boiler, a heat pipe heat exchanger. Gas cylinder steam boiler Branch Church of the trap in what place? Gas-fired steam boiler cylinders trap points at the bottom of the cylinder, which is a standard valve, are design specifications. Horizontal Horizontal gas steam boiler and gas steam boiler how much money each one, with a good restaurant to what kind of horizontal gas steam boiler, the price is no way to determine because the size depends on your power ! And because different manufacturers offer different quality and technology will be different. So, boiler safety accessories must be required to regularly check. Gas-fired steam boiler itself flawed: When the pressure component aging, strength weakened, or leakage, corrosion, deformation, scale and other defects, not timely maintenance in order to eliminate hidden dangers, but let boiler "sick to run," and so on. Therefore, the boiler must be regularly tested according to national requirements. Poor management, fireman officer is not responsible or low levels, lead to misuse. So fireman must obtain operating permits required. Four gas steam boiler safety accessories limit how often examined once? Four steam boiler safety accessories means that safety valve, pressure gauge, water level gauge, thermometer. General safety valve check once a year. General pressure gauge check at least once every six months. Water level should be washed once per shift. After checking with the thermometer mounted least once a year. How to change the temperature of the steam boiler the steam pressure of the gas changes.
In the national standard of water quality standard, the water quality index of 2 ton hot water boiler stipulates that the total hardness of water supply for chemical treatment outside furnace is less than 0.6 mmol / L. In recent years, in order to reduce the operating cost of heating units, some hot water gas-fired steam boilers have been overloaded due to the use of class Ⅲ bituminous coal as fuel instead of class Ⅱ bituminous coal designed to replace the designed type Ⅱ bituminous coal. During the maintenance in summer, it is found that the overloading boiler water wall tube fouling problem is more prominent, some boilers even occur tube burst accident. Why is heating hot water boiler overloaded, scale and even burst tube? Because the calorific value of class Ⅲ bituminous coal is higher, the type Ⅲ bituminous coal of the same weight is burned instead of the designed class Ⅱ bituminous coal. Bituminous coal increases the circulation of boiler riser is not absolute equilibrium, the geometric difference of riser and the heat load are different, so there is inevitably the deviation of flow rate between the risers. Due to the overloading operation of the boiler, some riser tubes are easy to overheat boiling because the flow rate is small, and the wall temperature is higher than the designed wall temperature, so that the scale and even the tube burst are easy to occur. How to prevent the boiler from scaling when overloaded? The heating hot water boiler operates under overload because of the scaling after the superheated boiling. Steam is produced in the process of superheated boiling. The water quality requirement of gas steam boiler is less than 0.03 mmol / L, which is much lower than that of hot water boiler. Water quality requirements. Based on the above reasons, the feed water hardness of heating hot water boiler is reduced, and the scaling phenomenon is eliminated by reducing 0.6mmol/L to 0.03mmol/L.
Atmospheric gas 2 ton hot water boiler several parallel operation policy in general, for a single heat atmospheric gas hot water boiler is relatively small, in order to meet the large heat load operating conditions, you need to run more than one parallel, then the two Taiwan atmospheric gas hot water boiler Weili, a simple energy-saving operation policy resolution. (1) temperature is below the water pipe network two temperature control curve setting value, to ensure a water supply pipe network without changing the temperature, by increasing the flow rate of a network to increase the heat supply until the electric control It is increased relative to the valve opening degree of 100%. In this process, by increasing the heating capacity of each atmospheric gas hot water boiler to meet heating needs. (2) Conversely, if the water temperature exceeds the pipe network two thermostat setpoint curve, at a constant temperature of the water pipe network of the premise, to reduce network traffic by reducing a heat supply pipe, in which the case, each sub-volume pressure hot water boiler heating by reducing the heat input per gas hot water boiler pressure and thus reduce the temperature of the water pipe network two. (3) When a plurality of atmospheric gas hot water boiler select start and stop the object by running the length of the cumulative duration is determined, the accumulated run time of the shortest atmospheric gas hot water boiler startup priority. In short, during the development of atmospheric gas hot water boiler operation strategy of several parallel, taking into account the issue of energy-efficient operation, during which the comparative analysis to be certain, and merit-based election.
