horizontal factory price oil steam boiler
2. szs series oil/gas boiler
The SZS is a modern D-type water tube boiler design, with gas tight membrane wall construction for all furnace walls including the front wall to maximize heat transfer. Tube manipulations for burner and man door penetration maintains optimum circulation. Two stage separation within the steam drum ensures high quality steam.
Boiler cleaning the necessity and significance of the boiler after a long run, the inevitable emergence of scale, corrosion problems, these problems are due to the generation of scale, so that the heat transfer deterioration, resulting in reduced efficacy boiler. It is difficult to achieve nominal evaporation; and since the heat transfer is deteriorated, such that the metal overheating, under pressure boiler, furnace tube bulge occurs even explode; poor thermal conductivity, so that the fuel consumption is increased, increased operating costs, boiler shortened life expectancy. Therefore, the boiler scale, should take the necessary cleaning methods. Of the boiler system operated at optimized state, it must be specialized chemicals treatment of boiler system water system: to remove scale, rust and anti-corrosion treatment: 1 chemical cleaning: adding a chemical cleaning agent to rust in the system , dirt, cleaning oil dispersion is discharged, reduced to clean metal surfaces; 2, routine maintenance: boiler scale inhibitor is added, to avoid rusting of metal, to prevent the crystalline precipitate calcium and magnesium ions. Boiler cleaning in two parts, part of convection boiler tubes, superheater tubes, air heaters, waterwall tubes scale, rust cleaning, i.e. water boiler water treatment, we used the final Li Jing Ling descaling operation, neutral cleaning technology cleaning operation, relatively low cost; cleaning of the part of the outer tube, i.e. the cleaning of the boiler furnace, we used high-pressure water jet cleaning technology, it is possible to achieve good results. 1, the cleaning operation may be neutral at neutral or weak alkalinity (pH 7-12) conditions, the water does not change the operation of the boiler a predetermined state index, do not stop cleaning, cleaning can reduce the loss caused by the stop, this is a the only signs of cleaning. 2, security theory and practice of running the boiler have proven non-erosive, washed acid-free cleaning under neutral conditions, the corrosion rate is less than the water washing of the corrosion rate of the metal, no corrosion damage to the metal. 3, non-toxic and pollution-free operation of the Spirit is a green cleaning products, boiler blowdown COD after its cleaning. BOD. The pH full compliance with national standards. 4, easy to use drugs added to the water supply can be, without a separate professionals, post operator can operate, it can be widely used. 5, a significant saving, the cleaning process in which water is the normal production water, unlike dispensing additional consumption pickling, passivation, and a large number of repeated washing of freshwater resources consumed. High pressure water jet cleaning technology uses water as the medium, so that the water system by special equipment to produce multi-beam, multi-angle, high-pressure water jets of different intensity. Internal cleaning object fouling, plugging, or be completely cut surface adhesion, crushed, pressed and washed in order to achieve complete cleaning. Whatever the fouling deposits, high pressure water jet cleaning device for cleaning, can be completely removed, which considerably metal color. It does not require chemicals, or corrosive flux, safety, and environmental protection. Boiler air preheater, waterwall, superheater, economizer heating surface and the like due to clogging of the exhaust gas temperature, boiler efficiency is lowered, increasing the wind electrical energy consumption; the fan will cause severe blockage afford pulling negative pressure oxygen furnace not enough, boiler forced outage. Using high pressure water jet technology, the cleaning effect is obvious. Equipment from high pressure water pump, water hoses, high pressure gun, special nozzle and other components. Cleaning process: water pressure via a high pressure pump to the 50 ~ 100Mpa, via line transferred to the system actuators work surface, forming a bundle of fine high-pressure water emitted from the nozzle with a high pressure water jet but powerful strike capability, which exit velocity up to 380m / s, the heating surface fouling rinse. The high pressure cleaning technology to clean, easy to adjust, cleaning equipment to be non-corrosive, non-polluting the environment, the effect is obvious characteristics, is an effective and a good way to save money and effort, especially suitable for solving air preheater clogging, severe coking furnace heating surface slagging problems. Generally reduce exhaust gas temperature of 4 to 12 degrees, the main improved reheat steam temperature of 0.5 to 5 degrees, to reduce electrical energy consumption for the wind, and early detection of creeping inflation, under scale corrosion risks, the unit safe and economic operation of very help.
In Harbin fifth session of the Fourth Session of the National People's Congress, coal-fired boilers governance as a key task to be mentioned again. Meeting specific targets: by 2019, Harbin will govern coal-fired boilers, boiler out of 35 tons and below do not have to upgrade conditions, starting 65 tons or more of coal-fired boilers and energy-saving ultra-low emissions transformation.
2019, Harbin will continue to strictly control the total amount and quality of coal, according to local conditions to solve the shanty towns, suburban town (township) village coal powder burning problem by briquetting, Burying to field, the way raw material cogeneration, effective path to explore the comprehensive utilization of straw, the straw open-air Jinshao continue to focus on the work to implement the required emission limits industrial emissions, car exhaust strengthen, kitchen fumes, dust and other site management, effectively improve air quality.
2018, Harbin City, air pollution, elimination of coal-fired boilers 1191 units, biomass boilers to replace more than 10,000 units, updated bi-fuel taxi 1270 units, 1323 units of new energy buses, comprehensive utilization of straw and prohibiting open-air work strength forward, ambient air quality fine days up to 312 days, an increase of 42 days over the previous year, the highest level since the ultra-high PM2.5 monitoring.
ZG boiler oil and gas boilers have hot water boilers that can be used for hot water supply and heating, horizontal factory price steam boilers for industrial steam supply, and power station boilers for power generation.
