central heating wns series gas fired hot water boiler

Learn the difference between pay professionals work and waste boiler and boiler feed water for boilers of knowledge and understanding, we will continue this work, because the only way to keep abreast of professional knowledge about the boiler, and the knowledge and flexibility to apply their knowledge applied to practice, then, to ensure that the boiler had good results, avoid misuse. 1. What is the boiler professionals work? Boiler professionals work, the specific name for the boiler professional engineers and professionals work into operation and maintenance professionals work. Run professionals work: the development of operational procedures, technical monitoring in the boiler, if the boiler fails problems during operation, timely analysis and guidance to operating personnel discharge failure, ensure that the boiler safe operation. Also, record the operating parameters of the boiler, to provide accurate data for the boiler overhaul. Maintenance professionals work: development of maintenance procedures and maintenance scheduling and parts planning, at the same time, but also to develop maintenance programs, guidance personnel for maintenance work as maintenance procedures. Boiler feed water and boiler feed water 2. Is there a difference? Boiler feed water, which is from the plant to the Water and then through oxygen between the boiler feed pump into the boiler economizer soft water, boiler feed water is from the chemical water softener after the plant by chemical treatment. Although they are soft water, boiler feed water, but more complicated, but also the need for oxygen and heated before entering the boiler. So, boiler feed water and boiler feed water is different. 3. central boiler furnace temperature to be controlled in a range? The boiler is the first inspection within or outside the check? Central boiler furnace temperature is generally controlled within the required range of 900 ℃ -1100 ℃. Is the first in the boiler inspection, conducted after the external examination within the inspection is completed, if the problem has been found in the inspection process, and after dealing with external inspection out of the issue. In addition, we also need to know that, in the boiler inspection is conducted every two years, external examination is conducted once a year. 4. What is the waste boiler? Familiar with and understand the waste before the boiler, first look at waste boiler. Waste boiler, which means that the exhaust gas, waste and waste water. Exhaust: no fuel to burn in the combustion waste air emissions, mainly including soot, sulfur dioxide, nitrogen oxides and other waste gases. Waste: solid waste produced after combustion of the fuel, including cinder, oil residue and other such waste. Waste water: Some water is not used in the boiler emissions, comprising a compound, mixture, suspension, and salt, alkali larger boiler water, in addition, also water, sludge and the like fluffy precipitate. Waste boiler, which is the use of some of these techniques and recycling waste utilization, and reduce noise to produce secondary economic benefits.

Hot water boiler water filling boiler considerations and parameters between boiler pressure central heating wns series fired hot water boiler of this kind in which the boiler is a common and frequently used species, but also in terms of all of us, need to have a comprehensive knowledge and understanding, because the only way to be correct and rational use of hot water boilers and have good results, but also to avoid misuse and adverse impact. 1. boiler parameters, whether on the same hot water boiler and steam boiler? From a professional point of view, the parameters of hot water boilers and steam boilers are not exactly the same, there are some differences, because the parameters of the boiler steam boiler steam boiler is concerned is the number of generated operating pressure and temperature steam, hot water thermal power boiler in terms refers to the boiler, the water supply and return water pressure and temperature. In addition, its different parameters, it corresponds to the unit is not the same. 2. Boiler Feed water pressure Cautions Boiler Feed pressure hot water process, there are some considerations, which is specifically as follows: (1) Sheung boiler heating system should be carried out separately, can not be together, because the boiler when you stop running between the boiler and the system is cut off. At the operational level, is you want to Sheung Shui to low water boiler expansion tank, then the system can Sheung Shui. Water Supply System, which can be used to perform Sheung pressure of the water filling the water system, if the pressure is less than water, circulating pumps can be used for water filling system. (2) If the system is filled with water by the circulation pump, which is specific to the operation: the boiler return pipe inlet valve is closed and the circulating pump will be multiplexed into the water pressure in the system until the system after the completion of charging water, then adjust the water level in the boiler. Meanwhile, while the system is filled with water, to be noted that the exhaust gas system. 3.1.4MV electric heating hot water boiler, heating area which is how much? 1.4MV electrically heated hot water boiler, its heating area is calculated, it needs to know the required heating power per square meter, heating, boiler pipes and boiler efficiency loss of these parameters, in order to obtain specific numerical values. If the heat required for heating power per square meter is 80W / h, boiler conduit 20% loss, then, the electrically heated hot water boiler heating area of ​​10,000 m2. However, this is the theoretical value, there may be some discrepancies with the actual value, without taking into account other external factors in this case.

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.

Gas Steam Boiler Water Wall Tube Explosion Analysis and Processing With the west-east gas project in-depth and complete, and the "coal to gas," the implementation of Beijing, Urumqi, Daqing and other cities and district heating heat source to promote the use of gas-fired boiler . More commonly used gas-fired boiler type D, type 0, A-type, p-type [1-2], these four basic types of furnaces by dividing the furnace cross-sectional shape. Wherein, D, 0, A-type small capacity boilers belonging horizontal boiler, boiler Ding is a large vertical boiler. The four furnaces are used membrane wall structure, eliminating the flue gas leak, reduce heat loss and improve the thermal efficiency of the boiler, ensure the stability of the structure. A compact, short installation period, high thermal efficiency, low noise, low energy consumption, low emissions, long life (design life 30a), adaptable load fluctuations and other characteristics can be controlled by computer program running faults and Protective function. Domestic slightly less than the amount of evaporation experience in the development of high-power gas steam boiler in the 75t / h or more, most of the development work is based on the introduction of Europe and learn from small gas steam boiler above. China's own design of high-power gas steam boiler in the course of running more than a vibration, burst pipes and other problems. This paper discusses some evaporation of the squib causes and treatment of boiler waterwall 160t / h of a gas steam.
