Then, from the automatic pellet boiler for home water injection up to the end of the boiler heating stop operation, the total injected boiler softened water is 2950 m 3. The atomic weight of Mg2 is 24 and the atomic weight of Ca 2 is 40. According to the results of water quality tests, the hardness of Mg2 is 2% and the hardness of Ca 2 + is 98%. According to this calculation, the amount of scaling in a heating cycle is as follows: 2950m3x0.03mmol/Lx1000L/m3=88.5mol. The amount of Mg2 is 88.5mol × 2%=1.77mol. The amount of Ca2 is 88.5mol × 98%=86.73mol. These two ions form scale in accordance with the final formation of CaCO3,MgCO3 sediment to simplify the calculation and at the same time explain the problem of boiler scaling.
How to reduce the amount of fuel hot water automatic pellet boiler for home? Currently, during boiler operation, the unnecessary loss of fuel is a more serious problem, then how do to reduce the amount of fuel to some extent it? (1) water quality problems, boiler feed water at the time of selection, try to water softening, water and avoid non-compliance, resulting in late boiler fouling and other phenomenon, attached to the inner wall, affect the thermal efficiency of the boiler, increasing fuel consumption. (2) to timely maintenance of the boiler, to avoid the smoke box and other parts of dust clogging problems, resulting in unnecessary consumption of fuel. (3) To regularly boiler dust removal equipment for testing, so it appears debris clogging. (4) under the premise of the normal operation of equipment, to the appropriate use of certain energy-saving technologies, on the one hand full use of energy, while avoiding unnecessary waste of fuel. In short, the process used in boilers, fuel costs expenditure in total expenditure also occupies a relatively heavy proportion, thus ensuring reasonable measures to reduce fuel usage basis for safe and stable operation of the boiler is more necessary, in its after comprehensive consideration, to enhance the effectiveness of production per unit time of the boiler is also very effective.
What structure and principles of industrial automatic pellet boiler for homes in particular? What structure and principles of industrial boilers in particular? Industrial boilers has become the hottest on the market boiler boiler. Whether it is gas or gas hot water boiler steam boilers, gas boilers generally use natural gas, liquefied petroleum gas and city gas as a fuel gas fuel. First, the working principle of gas steam boiler: the furnace and the combustion heat of the fuel gas steam boiler, heating pot of water evaporated into steam. Water pan (drum) in the furnace gases are fuel combustion energy released continuously heated, increasing the temperature and pressure steam is generated. When the boiling point of water increases with increased pressure, is sealed pot, the pot water vapor expansion is limited, and therefore the thermodynamic pressure (strictly speaking, water steam boiler). It is widely used as an energy source in the drum, the water is heated and vaporized again to saturation. Second, gas steam boiler basic structure: gas steam boilers and boiler drum consists of two body parts protection, instrumentation equipment, automatic control and protection system of continuous safe operation of its composition. This boiler water wall boiler drum boiler drum in the zoning arrangement, the first two return pipe fireworks smog chamber back to the drum. Connected between the drum and the tank, with water-cooling pipe and the downcomer, which constitute the framework of the combustion chamber. The pot is provided at the top with a steam water separator, to reduce the amount of water extracted from the steam. The bottom of the pan heating surface of the drum, and fireworks waterwall tubes.
We have learned to, Yan'an City, Shaanxi Province, Huanglong coal-fired automatic pellet boiler for homes in order to effectively promote the "clear" work, accelerate the improvement of ambient air quality, on March 18 held a coal-fired boiler demolition transformation mobilization. Chaired by Deputy Mayor, County Authority, Environmental Protection Agency, the Public Security Bureau and other coal-fired boilers Chaigai leading group member units and coal-fired boilers Chaigai involved 16 companies, units attended the meeting.
At the meeting, urban management bureau announced the "urban transformation of coal-fired boiler demolition plan", and county coal-fired boiler demolition work arrangements for the deployment. Program pointed out, the county government before the end of June to remove their coal-fired boiler steam tons per 20,000 yuan subsidy standards in accordance with the relevant provisions of the provincial coal-fired boilers Chaigai subsidies, Chaigai completed in the first six months to the end of August unit task of tons of steam per 10,000 yuan subsidy standards, after the completion of the end of August Chaigai units should be punished to the unit in addition to the removal of subsidies, the person in charge. unit responsibility.
A coal-fired boiler Chaigai work is the key point to win the Battle of the blue sky, the county is an important measure to improve the quality of atmospheric environment, the relevant units should fully understand the importance and urgency of the boiler Chaigai work, according to "own boiler demolition themselves, change themselves, government agencies take the lead in demolition, lead change, limited time limit must be removed, must be changed "requirement, carry it out;
Second, the change involved units to firmly establish the overall awareness, to overcome the luck, to seize the opportunity boiler Chaigai premium policy, a reasonable choice of the transformation of the way, adhering to standards, early arrangement, early deployment, early start;
Third, the government supervises the room should work together with urban management, environmental protection and other departments, inspectors conduct regular supervision, to dismantle ineffective, slow-moving unit, to be criticized, and timely feedback evaluation to do, do you want to do a good evaluation appraisal work; County JISC to errant Chaigai, affected units and individuals county atmospheric objective assessment of the results, in accordance with the "air pollution prevention of accountability measures" be accountable, accountability, ensure on schedule to complete the work Chaigai city coal-fired boilers.
