Why boiler always pay? Phenomenon: the pressure gauge shows the value of frequent falling, falling. Normal water pressure of the boiler must be greater than 0.8bar, replenishment cycle in 3-6 months or more. The boiler is connected to the cooling system in the room together to form the heating system. Pressure gauge is displayed on the boiler pressure value of the entire heating system, so that the replenishment is the replenishment of the entire heating system. Therefore, in most cases often pay a heating system problems that may arise, not the problem of the boiler. One reason: in the pre-commissioning of the new system heating system commissioning new air heating system more automatic exhaust valve release system results in reduced pressure, requiring multiple replenishment. Two reasons: heating system for leaks out pipe heating system or ground heat sealing leakage may occur at the interface and the leaks little leakage, since the heating boiler is in the state of the whole system is hot, so the leakage the rapid evaporation of the water is difficult to find the leak by the naked eye. If the pressure off the boiler and can not appear to find the leak, we recommend that you check the boiler leaks. Inspection method: After stopping the boiler operation, close the bottom of the heating boiler supply and return valves (the valve can ensure shutting), disconnected from the system directly to the boiler, the boiler supply water to an integer value, a period of observation to see if there are fluctuations in pressure gauge . This method may be simply determined to be a problem after the boiler or heating system piping valve leakage problem. Reason Three: The expansion tank expansion tank failures would result in failure of the boiler heating system pressure exceeds 3bar the boiler drain valve protection. Contact your dealer for a replacement. Four reasons: replenishment valve closed lax if replenishment valve closed lax and low pressure water pipe network, the system will fall in pressure when using hot water. Solution: If frequent replenishment of the situation, need to contact the service provider, check the heating system as soon as possible to avoid long-term damage to the boiler caused by replenishment.
Superheater tube boilers and boiler superheater its two operating state, if the squib phenomenon, then what specific reasons? And what is the dry and wet operation of the boiler? The main purpose of the two issues raised, in order to be a good and comprehensive solution, so we will be able to have a thorough understanding of, and at the same time, let's deepen their understanding of the boiler. Cause Analysis 1. Boiler Superheater tube. Boiler, if superheater appear squib phenomenon, its specific reasons, the analysis and summary boiler manufacturer box boiler, the conclusion is: One reason: superheater tubes, long-term operation in the over-temperature condition, even if overtemperature modest, but also the mechanical strength of the pipe material will be lowered, and so the creep speed, then there a thick bulging phenomenon, until the burst. Two reasons: the presence of foreign matter superheater tube, and a blocking phenomenon has occurred, so that the boiler combustion becomes unstable, so that the deterioration of the heat transfer pipe, the local temperature is too high, and further, the high temperature squib. Dry and dry-wet operation of the boiler 2. The boiler operation: this, in block boiler manufacturer boiler opinion, is that when the boiler load is above 35%, since the generated automatic steam boiler for dry cleaning machine is larger than the flow rate of the water wall, such that the superheated steam flows through the steam trap, but this time there is no water in the steam separator, so called boiler runs dry. Wet boiler operation: For this, according to the boiler block boiler manufacturers introduced the dry run is the opposite. Which means that when the boiler load is less than 35%, less than the steam in the boiler water wall flow, then the steam separator in the water. Therefore, this condition is called wet operation of the boiler. In fact, these two states boiler can be interchangeable, and will be affected by burn rate. If the steam flow through the steam trap becomes superheated steam, together with the effect of the temperature controller, and an effective control of the boiler feedwater flow it is correct and can achieve a smooth transition of the state.
