Horizontal hot water boiler are some considerations: Priming accident 1 boiler, combined 2 ton condensing steam boiler for sale Priming phenomenon (1) rapid fluctuations in the water table level from top to bottom, the water line blurred. (2) pot of water alkalinity, salinity seriously overweight. (3) with a large amount of water steam, decreased steam quality, superheater outlet steam temperature drops. Occurrence of water hammer (4) the steam pipe, the steam leakage occurs at the flange connections for leaks. 2, the processing Priming boiler (1) reduced combustion, little off main steam valve, to reduce the evaporation boiler, to reduce the load and remain stable. (2) fully open the drain valve on the surface of the drum (continuous blowdown valve) and a lower discharge drum appropriately. At the same time to increase the amount of water to reduce boiler water alkalinity and salinity, and you should pay attention to control the water level of protection. (3) boiler pot-treatment shall be discontinued dosing. (4) open superheater, the steam trap and a sub-cylinder pipe. (5) maintenance of the boiler water level slightly lower than the normal level. (6) notice water treatment personnel to take measures to ensure the supply of qualified demineralized water. Increasing the pot of water sample testing times, until the pot of water before qualified becomes normal operation. (7) before the boiler water is not improved, increasing boiler load is prohibited. After the accident elimination, should be promptly wash water gauge.
If the poor quality of water treatment equipment boiler water treatment when used, water efficiency is not high scale and corrosion will accelerate the boiler. The main reason for this phenomenon is the improper use of the resin so that the final oxidation damage occurred; or the inner wall of iron boiler did not receive timely and appropriate treatment results in the occurrence of iron poisoning resin; then, or is the boiler water as a river before no filtering process, so that the resin is not blocked sludge can play a role in normal. 4. no attention to the PH value of the boiler water
0.5 tph WNS series condensing gas-fired combined 2 ton condensing steam boiler for sale for plastic industrySteam boilers are the important heat source equipment in the plastics industry, providing sufficient heat for polymerization, dehydration, drying and thermoforming processes. JJS SRL is a Chilean company with more than 40 years of experience, specializing in the production of polyurethane products for a wide range of industries. Temperature is a critical factor in the production of polyurethane products. Generally, the polyurethane reaction temperature is controlled between 60 and 100 degrees. If the temperature is too low, the reaction rate will be very slow, which is not conducive to the reaction. Therefore, the stable operation of steam boilers plays a vital role in the enterprise.Recently, the Ministry of the Environment of Chile has made clear requirements for NOx in boiler emissions, stimulating that NOx emissions should be less than 30mg/m³. Hence, JJS SRL attached great importance to the environmental performance of steam boilers when purchasing. ZOZEN offered WNS series natural gas fired steam boiler according to its actual needs. This series of steam boilers adopts large-diameter corrugated furnaces with high-efficiency heat transfer element threaded tubes to effectively improve thermal efficiency. In order to achieve energy-saving effects and save fuel costs, ZOZEN also equipped energy-saving equipment such as condensers and economizers at the tail of the flue. And the advanced low NOx burner easily achieve the ultra-low NOx emissions.
"Coal to gas", "coal to electricity" is the trend in recent years of China's reform boilers, all regions are gradually improving. But because some areas coal to gas, coal to electricity-related project has not been completed, the pipeline can not be normal delivery of natural gas and electricity, but there can not ban the use of burning coal for heating, resulting in some of the people cold.
Under Thus, this year, Hebei Province, will carry out the inspection work cleaning heating dragnet, scheduled for November 1 to 10, requires each village and household dragnet inspection, the gas supply, power supply is not guaranteed to get the premise not allowed to first dismantle heating stoves.
Inspection team is more than 2,000 people drawn from the province's environmental protection system, divided into 120 large groups, each group of sub-1-2 large counties (cities, districts), take the main city limits off-site inspection, cross-check each other, such as thorough investigation way, a comprehensive understanding of coal to gas, coal to electricity and clean coal work on behalf of the double security for the situation.
Wherein, the village 500 (cell) is not less than 20% of households checks; 500 villages and above (cell) checks no less than 10% of households. The main inspection five aspects, including: gas supply, power supply security, security for the clean coal and distribution, development of contingency plans, etc. under extremely adverse weather conditions. In gas supply, power supply is not guaranteed under the premise, the focus in advance to see if the removal of heating stoves situation.
Environmental Protection Department official said earlier this year in northern clean heating to proceed from reality, insist on the need for constant, the gas will change to ensure that clean heating and warm winter are guaranteed.
