All those involved in the trial personnel in the company "professional life, work lean" under the guidance of the core values ​​of continuous fighting, the various problems couplet review group proposed were closed, one-time passed the ASME certification.

Preparation and method for measuring the moisture content of the flue gas of the which is the best central heating boiler water before the boiler purchase this product knowledge and understanding, the present, it is necessary for two reasons, first, it is the site of important product and the main key one word, and second, the products are widely used, why we have these conclusions and specific requirements. Meanwhile, I hope that we can be taken seriously and, in order to have learned well and apply their knowledge to practical work flexibly. Is there some preparatory work before the boiler 1. buy? Boiler products to buy, this is an important job, and need to be taken seriously, but also want to take into account all relevant factors, in order to have accurate judgments and the correct choice, a good choice to avoid mistakes. Before carrying out this work, is the need to do some preparation, use of the product to the environment and have a clear understanding of the requirements and learn about product origin, specifications, technical parameters, materials, quality, price, service and product manufacturers these and other basic information, in order to compare and consider, then, the right to choose their own products. 2. whether Sheung Shui before the boiler starts have specific requirements? From a professional point of view, Sheung Shui before the boiler starts, there are some basic requirements, which specifically is: If the hot water boiler, the water speed before it starts not too fast, not be less than the winter time Sheung Shui 4 hours, in other seasons upper water time of not less than 2-3 hours. And, at the beginning of the water, its water speed to slow. If the boiler is cold, it's inlet temperature in the range of 50 ℃ -90 ℃, and the difference between the water temperature and the temperature of the drum wall into the steam drum, not greater than 40 ℃. 3. What is the chain boiler? Chain boiler, which is a particular kind of a boiler, a higher degree of mechanization layers fired boilers, the time the track grate with a chain similar to these so called chain boiler A boiler. Further, it is a pre-boiler, the coal combustion process is completed in the movement. Advantage of this kind of boiler, the combustion condition is stable, high thermal efficiency and easy operation, in addition, its low concentration of dust emissions. However, it should be noted that the moisture content of the larger, more ash and strong coking coal, not suitable for this kind of boiler for combustion. 4. How the moisture content in the flue gas boiler measured? Determination of moisture content in the boiler flue gas, which is the weight measurement method, condensation method, and three psychrometer, and the moisture content of the flue gas is typically in the volume percent of water vapor in the flue gas content to represent. If dark gravimetry, need to use hygroscopic agent, the hygroscopic agent used is calcium chloride, calcium oxide, silica gel, alumina, phosphorus pentoxide, magnesium perchlorate and the like.

After the fuel oil is sprayed into the furnace, it is very easy to mix with air and burn rapidly and exothermic rapidly. Compared with the coal-fired which is the best central heating boiler water with the same parameters and capacity, the thermal strength of the furnace volume can be doubled to 1046.6 × 10 kilo coke / m / m ·h. However, in order to reduce the heat load in the combustor area so as to avoid the overtemperature of the water wall tube in this area, the furnace volume is only reduced by about 1 / 3. Because the ash content in fuel oil is very little, it can not form slag on convection heating surface, so the flue gas temperature of furnace outlet can be up to 1300 ℃, and the pitch between tubes of convection heating surface can be reduced to increase the flow rate of flue gas, so as to increase the flow rate of flue gas. Heat transfer coefficient of heating surface, saving heating area and steel.

10 tph and 6 tph SZS series water tube gas-fired steam which is the best central heating boiler waters for food industryIn the production processes of various seasoning vegetables including pickled vegetables, steam supplied by the boiler is required for processes such as high temperature sterilization and heating. Sichuan Jixiangju Food Co., Ltd. is a Sino-Korea joint venture committed in research, production and sales of high-grade seasoning vegetables and pickled vegetables. The products are sold all over the country and exported to many countries and regions overseas.In 2017, with the increasingly serious environmental issues, Jixiangju Food actively responded to the national "coal to gas" policy and decided to purchase low NOx gas-fired steam boilers. As a long-term partner of ZOZEN, Jixiangju Food expressed satisfaction with the operation of the coal-fired boilers previously purchased from ZOZEN. For the new demand proposed by Jixiangju Food, ZOZEN customized the boiler system and recommended two sets of SZS low NOx steam boilers to ensure the sufficient steam supply for the production line. This series of gas-fired boilers adopts D-type full-membrane wall structure, and the combustion chamber adopts Narrow pitch tube membrane water-cooled wall, which has good air tightness and reduces heat loss. It is equipped with energy-saving equipment added at the tail of the boiler flue to improve the thermal efficiency over 98%; the large-volume furnace design combines the advanced low NOx burner to ensure that the NOx emissions in the boiler flue gas is less than 30mg/m³, which has passed the environmental protection standards.
