natural circulation waste heat boiler

Gas-fired natural circulation waste heat boiler feed pump selection method! Water pump is the main equipment of gas-fired boiler, which is mainly used to replenish water of boiler to meet the normal water demand of boiler. The type selection of water pump mainly determines its flow rate and head. The specific introduction is as follows: 1, the flow calculation of feed pump: Q = k (Q1Q2): the flow rate of Q-boiler feed pump, m3 / h; Q1-Total water supply at maximum steam load for boilers, m3 / h; Q2-other water consumption, such as continuous discharge, periodic discharge and thermostat, m3 / h; k-standby factor 1. 1 ~ 1. 2.2, calculation of feed pump head of gas-fired boiler: h = H _ 1 H _ 2H _ 3H _ 4: h-boiler feed pump head, m; H _ 1-boiler opening pressure of safety valve under designed pressure, MPa; Resistance of H _ 2-economizer and water supply pipeline system, MPa; H _ 3-difference between the highest and lowest water levels of the water supply system, MPa; H _ 4 & mdash The other. 3, the gas-fired steam boiler feed pump shall be provided with a reserve, and when the maximum feed pump stops operating, the remaining total flow rate shall be able to meet 110% of the water supply required by all operating boilers at the rated evaporation capacity; When the boiler room is equipped with a dewarming device or a heat accumulator, the total flow rate of the feed pump shall be included in its water consumption. 4. One or more boilers with the same steam pressure may choose to operate side by side with two or more feedwater pumps, if the main pipe is used for water supply, Then you can choose two pumps and one backup, then frequency conversion water supply, which not only reduces the consumption of electric energy, but also makes the water supply pressure stable, although the one-time investment is relatively large. However, by means of frequency conversion and energy saving measures, the investment cost can be recovered in 3 years and 4 years. 5. Gas-fired steam boilers use steam-driven feedwater pumps as accident backup pumps. Its flow rate should be able to meet 20% ~ 40% of the water supply required by all operating boilers at rated evaporative capacity. Only when the boiler room with the first-class electric load and the feed pump stop running will not cause the boiler to be short of water, the steam-driven feed water pump may not be installed, and the non-power boiler room of the general industrial enterprise does not have such conditions, so it must be set up. Boiler selection has a direct impact on the boiler water supply system, it should be carefully selected.

Interpretation gas steam natural circulation waste heat boiler and advantages of the main features is the use of gas steam boiler steam boiler heated by a gas burner. Vertical steam boiler combustion engine underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency of the boiler, reduce user costs; horizontal steam boiler shell type three return all wet back downstream pyrotechnic pipe structure, large combustion flame in the combustion chamber a slight positive pressure, fully extended, low combustion heat load, the high heat of combustion efficiency, effectively reducing the exhaust gas temperature, energy saving, more economical, and a waveform furnace threaded pipe structure, i.e. increase the strength of the heat absorption of the boiler, but also to meet the needs of thermal expansion of the heating surface, scientific and rational, and durable. Select gas steam boiler and to consider the dimensions and the aesthetic appearance of the consideration of the size of the effect, when the selected white color packaging purchase natural gas boiler, it is not only elegant, but also white colored plate package having a good insulation effect. There is also the issue of natural gas boiler size. You need to put in place the location is very important. If the purchase amount is too large or too small, it will cause unnecessary trouble. Gas steam boiler explain the main features and benefits: First, we should know that the main role of natural gas boilers for heating them. Therefore, in the purchase of gas-fired, you should expect to see the packaging of raw materials. When selection time, to select a body made of glass wool, glass wool insulation as very good, very light weight. In this way, there would be no boiler heat loss. Once the heat boiler quickly disappear, it will not provide more energy for us. Productivity will decline rapidly, more will be destroyed. gasoline.

When using the steam natural circulation waste heat boiler should be noted that the scope of matters steam boiler is wide for all to see, as long as it can be used in place basically have to use steam to the steam boiler. And when using steam boilers where we should pay attention very much, on the next following three aspects do a brief introduction: 1, the installation, the installation of step-outs is very important, because the purchase is not the time to steam boiler as a whole, the seller will many parts of the steam boiler and then transported home in a professional staff responsible for the installation of a steam boiler. If the installation work not done, then there will be a lot of problems in the use of the back, so that a small screw into a large boiler requires very seriously at the time of installation. 2, maintenance, use any machine in the process required in both their professional and do maintenance work, especially for the usual cleaning various parts inside the boiler and machinery, dust removal work must be done, otherwise the impact is first re-appearance who is, will affect the normal operation of the machine, affecting work at the same time it is likely to be hazardous to people's health. After 3, repair, no matter how reliable machines in use for some time it is likely to cause a variety of problems, which use errors when users use is also a problem of placement. For steam boilers same is true for a lot of people use the time did not follow the correct way to operate a steam boiler will lead to emergence of a variety of injuries, something has gone wrong will be able to ensure timely maintenance of normal steam boiler operation.

China Dunhuang International Hotel relevant responsible person said, party fast or aftermarket both in pre-sales, remained consistent patient service, we have solved many difficult problems, with fast natural circulation waste heat boiler, we are assured. --customer feedback
