condensing light oil fired vertical water boilers

7MW WNS series gas-fired hot condensing fired vertical water boilers project for Sinopec Beijing Design InstituteA hot water boiler is an important heat supply equipment in the national economy, there are two main functions: supplying bathing water and heating water. Sinopec Beijing Design Institute (BDI) is the first design institute specializing in chemical and petroleum refining engineering since the establishment of PRC; it was restructured and amalgamated with former Sinopec Engineering Incorporation (SEI) and Beijing Petrochemical Engineering Co., LTD. into New Sinopec Engineering Incorporation, affiliated with Sinopec Group. The major job of New Sinopec Engineering Incorporation is oil refining and petrochemical design. Chinese government boosts the "coal to gas" or "coal to electricity" projects to protect atmospheric environment and promote energy transformation. BDI decided to eliminate hot water boilers that cannot meet the emission standards and introduce energy-saving and environment-friendly ones to support the development of environmental protection; they decided to use the natural gas as fuel. ZOZEN stood out from the fierce competition of boiler market and gained the favor and trust of BDI, ZOZEN provided BDI with 4 sets of 7MW gas-fired boilers (WNS7-1.0/115/70-Q). This series of boilers is the typical environmental protection and energy saving product, full automatically running is safe and reliable; the thermal efficiency is over 98%. All figures of the boilers are above the design requirements and have reached the international advanced level.

Pressure fire operations and precautions Henan fast boiler's steam boiler Xiao Bian told you about the operation of steam boilers and pressure fire precautions and stainless steel high temperature magnetic pump structural characteristics 1. pressure steam boiler fire steps of (1) to reduce boiler load, according to the length of time of shutdown, the seam thicker, the thickness is generally not more than 200 mm, suitable to accelerate the speed of the grate. (2) to the slag is thickened seam about 1 mm from the stop grate rotation, the drum is stopped, the operation of the induced draft fan, blowing off a small segment of the regulating plate stopper and dampers qs, relying on natural ventilation to maintain coal the lean-burn, the sewage, boiler water level will rise to the maximum allowable level. If the fire burn coal gate, grate can be switched on again, the coal-fired back, a distance. (3) the recovery boiler needs to run, as long as the opening lead, a blower, to adjust the smoke, and the wind baffle plenum segment adjusting the opening degree of the shutter, the adjustment of combustion steam boiler seam thickness to be normal, start grate, can be restored run. 2. Note the use of a steam boiler (1) before starting Check power supply voltage, there are unusual circumstances water, close the drain valve opens the water supply valve, check whether the pump stuck, stuck if the pump, remove the fan cover, rotation of the motor shaft to the flexible state to boot. (2) When the steam boiler maintenance or replacement of parts, turn off the power to avoid live work dangerous. (3) electronic control box, pump motors and other parts should avoid damp water to prevent burning boiler should pay attention to keep clean. (4) steam boilers in accordance with quality requirements, when using the apparatus sure to install a water softener, the water softener is not used because the boiler may cause fouling, may cause serious squib, shortening the life of the boiler. (5) Please note that when using sewage. And at least once a day with a discharge pressure of between 0.1MPa to 0.15MPa discharge may be prevented clogging of pipes, sewage should be properly connected, to guard against burns. Stainless steel high temperature magnetic pump structural features: a sliding bearing magnetic pump sliding bearing materials impregnated graphite, PTFE and engineering ceramics. Because of engineering ceramics has good heat resistance, corrosion resistance, abrasion performance, so the sliding bearing magnetic pump more use of engineering ceramics production. Because of engineering ceramics are brittle and expansion coefficient, so the bearing clearance is not too small, so as not to hold the shaft accident. Since the magnetic pump in order to lubricate sliding bearing medium conveyed, it should be used depending on the medium and conditions, making use of different materials bearing. 2. Cooling lubricating fluid flow control pump operation must be flush cooling internal friction annulus region between the sliding bearing and the magnetic rotor and the containment shell with a small amount of liquid. Coolant flow rate is typically 2-3% of the design flow of the pump, the annulus area between the inner magnetic rotor of the eddy current generated spacer bush high heat. When enough cooling lubricant or flushing holes poor, clogging, the medium will result in a temperature above the operating temperature of the permanent magnet, the inner magnetic rotor gradually loses its magnetism, the magnetic force actuator failure. When the medium is water or water-based liquid, the temperature rise can be maintained in the annulus region of 3-5 deg.] C; or when the medium is a hydrocarbon oil, allows the annulus region of the temperature was maintained at 5-8 ℃.

How to reduce the scale of known gas steam boiler steam boiler heating surface of the machine is the primary supply of high quality steam. Past, steam appeared to mankind brought great changes. The emergence of the steam era of human civilization introduced the modern era. Now there steam boiler once again that human potential is unlimited, it appears there are a lot of people to help. Steam boilers plays an important effect on people's day in. It's like bathing, eating, and other industries. It is said that the local demand for steam boiler steam demand. Steam boiler steam supply is the primary tool. Industrial production in the steam boiler to supply steam for the people, with the production of human power supply, making it easier to produce in the production. In the days of steam boiler supplying steam can help people make food, why we can take a bath with a steam boiler in the cold winter. These are to help supply the steam boiler. Steam boiler steam can easily supply better for us to make our life easier and more convenient. About steam boiler, we should be careful when they use their maintenance work, so that it can help us longer. Steam boiler in direct contact with the heat exchanger, the high heat recovery, contaminants in the flue gas are also removed, but acidic water quality, which is not convenient for the hot condensing fired vertical water boilers. The so-called direct heat exchangers is that we often call for means for recovering heat from the flue gas condensation. Now, more and more people choose to use the steam boiler, the share of the market share continues to add. Flue gas discharged from the steam boiler containing a lot of water vapor, is condensed through the release of a lot of the latent heat of vaporization, which is more than a coal-fired boiler. a lot of. This boiler better selection of direct heat exchanger. Industrial production is the primary driving force of the world expanded, is very important for the expansion of the world. Therefore, we need to use steam boiler supplying steam better for us, because of our human expansion needs of these sophisticated machines help. No machine age is primitive society. When humans learn to use tools, it marked the beginning of civilization has already begun. Steam boiler is a tool we humans can do to help expand. No matter how preparedness, gas steam boiler, after working long hours, more or less will have some scale. Gas steam boiler is in operation, the furnace will be a series of chemical and physical reactions, the application process, will form a strong and fine scale on the heating surface, which would lead to a direct heat exchange efficiency of the boiler decreases; and by the effects of corrosion under the scale, will lead to reduced water wall furnace heat absorption gas steam boiler, then dropped thermal efficiency, waste of capital investment. The necessity of finishing scale there is little that is durable stable job and let the boiler down. As long as the thermal conductivity of the scale of one percent of the steel, once the heating surface fouling, so that the heat transfer will be impeded, in order to maintain the boiler must be output in the use of the process, it is necessary to progress the fire-side temperature. Process outlet temperature of the furnace gas steam boiler making added, so it will make the loss of added gas steam boiler, reducing the heat transfer effect that it would be useful after fouling equipment in the water wall, so it is very likely Add water wall tube wall temperature can cause lead to burst pipes water wall. Cleaning the boiler becomes particularly important. Performing the cleaning process, you can use efficient, environmentally friendly and non-corrosive cleaning agent, so that the device will reveal the original metallic tube, down to fouling. Secondly, in the incinerated gas steam boiler, furnace needs careful investigation smoke temperature and the temperature of the main steam changes; when the main steam pressure in the rising condition, if the boiler burning smoke temperature rise speed or does not rise significantly Pianman, immediately Check the oil gun fire situation.

Recently, Shaanxi Province issued a notice "issued four Battle 2019 program of work".
