hot water boiler used in greenhouse

Around the 1940s, the war promoted the development of technology, and in the case of urgent military and economic needs, led to the development and successful application of marine oil-fired boilers.

Selection of industrial boilers depends on what issues now in order to begin purchasing production development of low nitrogen boiler requires a huge supply of thermal energy, and industrial boilers can be used to provide heat. Our usual electricity, water, food, drink, wear life industry involved, as well as heavy industry requires its abundant supply of energy. So for businesses, the choice of a good boiler is particularly important, so we have chosen high quality and durable industrial boilers depends on what issues? First, look at the quality of the pros and cons of general industrial boilers, high-quality industrial noise will be relatively small boiler, the boiler will reduce its own noise vibration, let the system is relatively more stable, which can make it a longer life . The main material quality industrial boilers will be very thick and strong resistance to stress, and external boiler will be embalmed, so that its life will be longer and more secure. So we can see the merits of its quality in the choice of the boiler and then make your selection. Second, look at the strength of the energy performance of industrial boilers industrial boilers in operation will consume huge amounts of fuel and produce a lot of waste discharge, which consume a large amount of money but also cause environmental pollution, industrial boilers and domestic professional in raw material savings and reduce carbon technical level of emissions is more the color. So we choose, we can understand more about whether the province boiler fuel is environmentally friendly and energy-saving technological achievements boiler manufacturer to master, and then compare selected. Third, look at the quality of its after-sales support services in the choice of a good industrial boiler manufacturer after-sales support is a very important issue, then why is it important? If you choose to manufacturers provided us with a good service, then we can reduce unnecessary waste of human and material resources consumption, there will be a better experience for the boiler. There are many factors in the choice of the industrial boiler when the need to consider, we can mainly from its own good or bad quality and the strength of its energy performance, and make the appropriate selections from the manufacturers of after-sales service are in place to protect these three important aspects in general, high-quality industrial boilers will advantage both of these three conditions.

July 26, 2016, Beijing, China Everbright Paper Co., Ltd. and the company signed a "split 6 tons of steam condensing gas steam boiler contract" by the company responsible for the WNS6-1.25-YQ split condensing gas boiler steam to all production, installation and commissioning work. The product is the use of condensing technology, effective emission of harmful substances SOx, NOx, COx, is industrial boilers efficient and environmentally friendly solutions.

Gas boiler is operating at low load, how to do the boiler load is the ability of a boiler to generate steam in a unit run time, from another point of view, is acting within the boiler work, the more shows that the boiler unit of time in a high-load condition, the unit of time It indicates that the boiler is acting at least low load conditions. To ensure normal operation of boilers, combustion systems and circulation system should remain stable state, according to the operational standard in terms of the boiler, the boiler should not be a long period of evaporation to 50% or less of rated load. 1 harm low load operation, affect the normal operation of the boiler: the combustion unstable, difficult to adjust the control returns, may cause a sudden turn off the boiler. 2, affecting the life of the boiler: low load combustion gas and smoke emission inputs unbalanced situation may occur, so that uneven heating of heat exchange tubes, pipes easily lead to local overheating, causing overheating of the wall, will increase the long-running the probability of occurrence of burst pipes. 3, could easily lead to pipeline corrosion long-term low-load operation, the exhaust gas temperature will decline, increasing the low-temperature corrosion of heat exchange tubes arranged in the tail of the probability of occurrence. 4, affect the boiler thermal efficiency: low load operation of the furnace will reduce the temperature will result in incomplete combustion, boiler efficiency. Low load operation handle 1, gas boiler is found to always pay attention to changes in boiler pressure lower loads, fire control, and air volume ratio, so that it is operated at a predetermined pressure, over-pressure, over-temperature operation will not recur . 2, fireman should open the recurring pressure gauge, pressure gauge flushing the trap, to prevent clogging; Rinse once per shift pressure gauge, to prevent false water level. 3, always pay attention to changes in boiler water level to keep it at a normal level, prevent the emergence of the boiler dry. 4, the protection of the safety valve is the last line of defense after the failure of all automatic protection instruments must be checked regularly, once every two weeks to manually open the vent to prevent rust. 5, when in the low-load operation, but also noted that the use of gas, to increase or decrease the amount of gas introduced into the actual situation, to ensure full combustion of gas.
