In the low profit era of Chinese paper packaging industry, entrepreneurs have been turning their attention to internal management, increase business efficiency by saving energy. At present, the paper packaging industry equipment many of them appear old and comes with a variety of issues, in particular energy use seriously inadequate problem is solved and bear the brunt of reform issues. So we must make an effort in the use of energy, use energy-saving equipment for the industry, in order to solve the problem fundamentally.
The inlet speed of gas-fired hot-water boiler before start-up should not be too fast, usually no less than 4 hours in winter, and 2-3 hours in other seasons, especially in the initial stage of water intake. The inlet temperature of a gas-fired hot water boiler is generally 50 °C, so the difference between the feed water temperature and the steam wall temperature in the drum is less than 40 °C. For gas-fired hot water boiler, the inlet water temperature can be equal to that of steam drum wall without complete cooling, otherwise the inlet water speed should be slowed down. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too Large, the inlet speed is fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. When feed water enters the drum, it always first touches the lower part of the drum. If the difference between the feed water temperature and the drum wall temperature is too large, the inlet velocity Fast, and the upper and lower walls of the drum, the inner and outer walls will have a large expansion. Bad, on the drum caused a lot of additional stress, resulting in drum deformation, serious cracking. Due to the thickness and slow expansion of the drum wall, the tube wall connected to the drum wall is thinner and expands faster. If the inlet temperature of the gas-fired hot water boiler is too high or the inlet speed is too fast, the expansion will be uneven, the welded joint will appear cracks and the gas-fired hot water boiler will be damaged. The inner diameter of the decompression tube is usually φ 7~13mm (water and steam), and its length should not be too long (< 60m). The diameter of the pressure pipe is too small and the length of the pipe is too long Long, will affect the dynamic transfer of pressure measurement, increase dynamic error. The inner diameter is too large to be easily maintained and installed. Pressure pipes should not be placed in the horizontal part to prevent the accumulation of bubbles (when measuring liquids) and water columns (when measuring gases). The flow of a pressure tap perpendicular to the medium. Pressure faucet must not have chamfer, flange and burr. When measuring the hydraulic pressure of an electrically heated horizontal tube steam boiler is not working, the pressure outlet should be removed from the lower part of the pipe to prevent the gas in the liquid from entering the pressure guide pipe; When measuring gas pressure, the pressure splice should be removed from the upper part of the pipe to prevent dust and water droplets from entering the ignition line .
Area gas boiler heating gas boiler accurate measurement method is now occupied most of district heating, but heating in the heating area, indeed never specifically talked about today Xiaobian find some relevant content to share to you, you can use to confirm. 1. Gas boiler heating area thickness measurement method. Thickness measurement method using a thickness gauge that the wall thickness of the gas boiler heating surface area wear or corrosion thinned tube, the tube is used to determine the degree of thinning. Method for checking the thickness measurement of various heating surface, particularly suitable for checking internal heating surface tubes corrosion. 2. A gas boiler heating area vernier caliper measurement. With a vernier caliper to tubes of the heating surface is easy to wear or swelling burn site was measured, in practice, typically superheater or reheater tube wall temperature measurements up areas, to verify whether the tubing expansion thick, wear or corrosion. Significance with a vernier caliper to easily burn the heating surface tubes wall temperature measuring swelling in that the heating surface tubes and the measurement site recorded measurement results, the values obtained for the measurement at the same site compared with the next overhaul, gas heating surface tubes to determine readily fired boiler burning site bulge swelling tendency, as the basis for future maintenance. 3. A gas boiler heating area of the spacer caliper measurement. Spacer caliper is in accordance with various specifications of the tube heating surface, a number of manufacturing a caliper fixed dimensions, the size of each pipe, the two or three different sizes caliper according to its production of pipe material . The caliper is the maximum value of the maximum thick carbon steel pipe expanding the outer diameter of not more than 3.5% or the maximum expansion of crude steel pipe does not exceed a predetermined outer diameter and 2.5% prepared, carried out with the maximum pipe diameter measurement caliper according to the material of the tube it can be determined whether the tube exceeds a predetermined expansion crude. The minimum caliper is the maximum amount of thinning of the tube wall thickness of the pipe does not exceed 1/3 of the fabricated, for the pipe diameter with the minimum calipers measured, based on the tube exceeds a predetermined amount is thinned. Employed, spacer caliper measurement exceeds a predetermined heating surface tubes, with high efficiency, high inspection speed, reduce labor intensity inspection personnel and so on. The maximum caliper is used to check gas boiler superheater or reheater tubes exceeds a predetermined expansion crude measurement tool, and the minimum caliper is used to check the superheater, reheater, economizer, or wear, corrosion exceeds a predetermined measurement tools.
In summary, the difference between the atmospheric pressure hot water boiler and hot water boiler mainly in furnace pressure changes, whether the water level under control and whether there are structural limitations in three areas. In fact, the difference between the two is far more than that, they are there is a difference in terms of service life, water supply, safety performance, if you carefully study will certainly find many differences, but the most important is to combine their own needs to consider, select which type of boiler products.

Jun 25, 2014 · If the piping can't separate the water from the steam, the water will condense the steam, and your boiler will never build pressure. With this problem, you won't be able to heat the building either. So if you have no pressure and not heat, check the piping, the water's cleanliness and its pH.Learn More
