feed factory oil-fired condensing hot water boilers
Ovens and boilers boiler inspection methods oven to cook and cook blast furnace blast furnace inspection can be found as soon as possible the existing boiler problems and avoid boiler safety accidents in use, today we are speaking about the oven and cook for blast furnace boiler the inspection methods: 1, chain grate cold test run more than 48 hours. 2, coal gate installation is completed, the shutter plate on the coal should be closely good coverage, and other impurities to prevent leakage into the coal, coal stuck up and down the shutter, the shutter connected to water cooled coal, firing the door open and flexible. 3, boiler and subsidiary equipment Ge all assembled and pressure test qualified. 4, the end of the furnace wall masonry and insulation, and check whether the debris inside the flue cleaned. 5, thermal instrumentation boiler should check eligibility, and check the reliability of the boiler feed water, as well as water to the boiler to full level. 6, the required auxiliary oven test run is completed, such as pumps, fans, etc., have confirmed that each part of the work safety conditions to start, you can start the oven. 7, the furnace wall should be installed measurement points or sampling points. 8, all moving parts and should be required to add oil cup oil. Learn how to do the oven and cook blast furnace boiler inspections, I believe you must have learned a lot of knowledge of it, I hope this can help you use the more secure the boiler.
Innovation is the fruits of their labors in a timely manner to protect them, the group also set up a patent Group, to build the company's model workers Innovation Studio. By the end of 2017, the company applied for by the State Intellectual Property in standardization work, the establishment of a patent technology management platform. Industrial enterprises wang-wang, the city industrial prosperous and strong. Fast boiler threw himself into the path of innovation and intellectual development in the areas of clean fuel boilers, boiler industry forward to promote the development and enhance the overall strength of Anyang City, make yourself a contribution. Right now, fast boiler being saved enough strength, stir live a pond, in a move by chasing new road.
7MW WNS series gas-fired feed factory-fired condensing hot water boilers project for Sinopec Beijing Design InstituteA hot water boiler is an important heat supply equipment in the national economy, there are two main functions: supplying bathing water and heating water. Sinopec Beijing Design Institute (BDI) is the first design institute specializing in chemical and petroleum refining engineering since the establishment of PRC; it was restructured and amalgamated with former Sinopec Engineering Incorporation (SEI) and Beijing Petrochemical Engineering Co., LTD. into New Sinopec Engineering Incorporation, affiliated with Sinopec Group. The major job of New Sinopec Engineering Incorporation is oil refining and petrochemical design. Chinese government boosts the "coal to gas" or "coal to electricity" projects to protect atmospheric environment and promote energy transformation. BDI decided to eliminate hot water boilers that cannot meet the emission standards and introduce energy-saving and environment-friendly ones to support the development of environmental protection; they decided to use the natural gas as fuel. ZOZEN stood out from the fierce competition of boiler market and gained the favor and trust of BDI, ZOZEN provided BDI with 4 sets of 7MW gas-fired boilers (WNS7-1.0/115/70-Q). This series of boilers is the typical environmental protection and energy saving product, full automatically running is safe and reliable; the thermal efficiency is over 98%. All figures of the boilers are above the design requirements and have reached the international advanced level.
How to use gas-fired boilers can improve the thermal efficiency of the gas boiler is also bad choice will directly affect its thermal efficiency, so we are in the process of buying, be sure to choose good quality. In fact, the factors affecting it improves the thermal efficiency of many, so we regularly thermal conductivity of the gas boiler for cleaning and maintenance, etc., so as to extend its service life. Selection of good thermal and oxidative stability, strong anti-coking. Be careful not to choose odor and color depth of the election furnace. Life with carbon residue, an acid value, flash point, viscosity 4 measure. Make semiannual oil testing, in order to grasp the good quality operation. Identify problems and timely replacement, and find out the reasons and preventive measures in advance deterioration. At the same time it must strictly do not mix different product numbers to use. When used in strict accordance with the rules furnace, to avoid emergency fire heating (temperature rise rate which should be controlled at l0 ~ 40 ℃, h), over-temperature, over-pressure, to take emergency shutdown measures quickly and decisively, always observe the oil level and the oil expansion tank temperature. Such as the lack of oil should be added. Prevent air and water into the oil circulation system. It will accelerate the reaction (the oxidation rate at two-fold increase for each increase in L0 deg.] C temperature) after direct contact with air because of high temperature, high temperature oil to prevent direct contact with air. A better approach is inflated with nitrogen gas to the upper space of the sealed tank. Forming a protective gas layer, sealed under nitrogen unconditionally. To header tank temperature generally does not exceed 60 ℃, header tank is not directly connected in series within the circulatory system. Improve the thermal efficiency of the furnace hot oil boiler, timely removal of the inner wall of the furnace, plate line grime on the walls, in order to ensure good heat transfer, and should use a better quality of gas as far as possible, so that the heat generated by the combustion of coal in time, fully passed to it.
