Currently on the market the type of gas boilers complicated, many users are facing so many types of gas-fired, many technical terms not quite understand, I do not know where to start.
Little technical station: teach you to deal with waste water natural circulation high pressure boiler best qualitys in long-term use, water treatment equipment will inevitably aging, when the device is not functioning properly, dirty denser water supply, water supply process contains a certain amount of sediment. When more and more with water containing the sediment component in the boiler was evaporated, and precipitated sediment substance, the boiler can lead to clogging of pipelines, the heat dissipation is poor, the probability of the boiler will squib. If water boiler slag formed irregularly discharging furnace, the clogging of the tubes will cause tube rupture. But also reduces the heat transfer. Boiler Blowdown purpose: to avoid the failure of the boiler, reducing the consumption of the boiler, to save energy and prolong the life of the boiler. A discharge wastewater treatment boiler 1, a continuous process: the number of frequent discharge, exclude the use of blowdown boiler bottom slag, and using the time interval small number of high sewage discharge method, a ratio of long sewage works much better way. 2. Reduction Act: first do the above said continuous disposal method, and then reduce the amount of effluent, the role and purpose of doing so is to ensure adequate supply of boiler, and boiler water quality can be controlled within the standard range, not because excessive blowdown leads to large fluctuations in boiler operation, maintenance and life span of the boiler is very serious. 3, time control: the use of boiler blowdown consistent time intervals to control the balance of water quality, making the boilers run more stable and healthy. Second, the wastewater treatment process boiler 1, porous ceramic filter plate works porous ceramic filter plate consisting of aggregates (quartz, alumina, silicon carbide, etc.) blended in certain binders, pore formers, rare earth resist, high temperature sintering, the ceramic plate is formed in a uniform size distribution lot, arch-shaped openings and interconnected microporous channels, when fluid passes through these tiny channels, suspended impurities in raw water, colloid particles, macromolecules, etc. trapped fluid generates various physical effects on the outer or inner surface of the microporous channels achieve mechanical screening, purification, or diffused, fluidized adsorption entrapment and other effects. 2, Sedimentation porous ceramic filter plate for suspension slag boiler water concentration wastewater treatment process of the boiler or the boiler bottom desulphurization dust discharged water up 100000mg / L or more, if directly into the porous ceramic filter, the filter increase the number of load and cleared of slag, thus still uses the old process, a high concentration of ash into the water tanks horizontal sedimentation settle, the settling time is generally 1 to 4 hours, 80% of the large particles settling down in the sedimentation tanks, and then flows into the first two lattice filtering tank for further processing. Sedimentation using a mechanical grab slag ash sedimentation tanks in the precipitation tank to maintain a continuous use. Water in less ash, ash deposition amount is small, can be designed into two lattice precipitate was filtered tank, a grid artificial slag, the operation of another cell used. After the pools filter effluent suspension by advection sedimentation or clarification is still as high mechanical acceleration 1000mg / l approximately, the smaller the particle size of fly ash, generally in 100um or less, that the most difficult part of fly ash, by natural sedimentation, settling velocity is slow in settling effect, this is the processing method of the original precipitation suspension is often difficult to reach because the emission standards. This process increases a grid behind sedimentation filtration tank, mounting a plurality of channel walls in the porous ceramic filter filter, gray water to the outer surface of the filter wall into the filter through the porous ceramic wall intermediate the ditch, and then concentrated pool water flows, the cement clinker ash impurities can not pass through pores, filter is blocked outside the wall, is formed from the filter layer, similar to the membrane filtration layer cladding, water becomes clear and transparent was filtered through the precoat layer. As the filter constantly, gradually thicker coating coated film, resistance increases, decreased production of water, filter the water level gradually increased, but when raised to a higher protective position, the filter should start cleaning, cleaning cycle is generally in about 60 days. The cleaning method may be used within the mud pump ash hopper ash periodically pumped sedimentation tanks, so that continuous operation using filter; small filters filter the water tank can be emptied manually dislodge the ash collection pits, then gun after washing the filter can be restored wall surface.
1. The reasonable heat speed design of each heating surface of the waste heat boiler will help prevent dust accumulation;
2. The waste heat boiler adopts a straight-through arrangement, which can use self-removal of ash by dust self-respect, can keep the heated surface clean and improve the heat transfer efficiency of the boiler;
3. The waste heat boiler should organize the flue gas power field reasonably to make the flue gas flow smoothly and evenly to avoid biased flow. At the same time, a special anti-wear structure is used to help prevent boiler wear and increase the life of the boiler.
As a global natural circulation high pressure boiler best quality enterprise, Fangkuai Boiler attaches great importance to the opportunity of communication with customers. Therefore, we have set up a sales team of more than 100 people to visit customer units regularly to check the boiler operation status. Not only can timely search the customer's use feedback and boiler improvement opinions, provide a clearer development direction for equipment research and development, but also assist users in the testing and commissioning of boilers and maintenance work, full life cycle services, and solve customer cooperation projects. The problem is that nobody cares ".
2019-7-29 · A high-pressure boiler is defined as a boiler in which steam or vapor is generated at a pressure equal to or greater than 15 psig, or a boiler in which water is heated at a temperature of 250°F and a pressure greater than 160 psig, when water is heated for use external to the boiler itself.Get A Quote
In a boiler with free natural circulation, the generating tubes are installed almost horizontally, with only a slight incline toward the vertical. When the generating tubes are installed at a much greater angle of inclination, the rate of water circulation is greatly increased.Get A Quote
Oct 01, 2013 · Natural-circulation boilers, such as package D-type boilers that are fired with oil, gas or solid fuels (Figure 2a), are widely used in the chemical process industries, petroleum refineries and power plants. Their capacity ranges from 20,000 to 300,000 lb/h with steam pressures from 100 to 1,500 psig.Get A Quote
Warming lines permit natural circulation through the pump when it is shut down and the boiler is off line. Experience with offline recirculation systems has shown that thermal shock differentials can be reduced to less than 100F (56C) from previous levels of 200 to 400F (111 to 222C).Get A Quote
the 18th century, the design of boilers has evolved so as to increase efficiency as well as steam pressure and temperature. In In the United States, the energy consumption of industrial boilers accounts for 37% of total energy use in the industrial sector.Get A Quote
Typical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. As the water removes heat from the tubes, the water temperature increases and it rises to the boiler steam drum.Get A Quote

Based on circulation there are 2 basic designs of water tube boilers: Natural Circulation Boilers and Forced Circulation Boilers. Natural Circulation Boilers are the type of boilers where water circulates naturally that is due to the density difference. The difference in density is created with the difference in temperature of cold and hot water.Get A Quote
