Use of fan on boiler

The boiler is a kind of machine that uses coal to supply heat energy, so the boiler should use ventilator in the process of using it. Today we will talk about the role of the ventilator in the boiler.

Steam boiler can transport a large stable of high-temperature steam for the food processing, chemical production, medical and pharmaceutical, paper and wine industries, encourage enterprises processing and production processes. At the same time, the steam boiler is special pressure equipment clearly defined our country, whether it is to buy, install or use, have strict operating standards will minimize the risk factor. We in the selection of a steam boiler, be sure to shop around, comprehensive comparison, in order to buy into the appropriate steam boiler. So, what factors should we pay attention to it?

Security door energy saving effect of energy saving boiler boiler safety door is a must-have component, it can play a role in protecting the boiler. Today small as we summarize some small knowledge of security doors to share. Security door is a very important energy saving boiler protection device which prevents over-pressure and pressure parts of the boiler accident occurs, thus ensuring the safe operation of the boiler. In the statutes of the boiler on the arrangement position and the amount of exhaust steam safety gates are very clearly defined. For example, some parts of the hot water boiler must be installed a security gate: outlet superheater, reheater inlet, outlet and shut-off valve once-through boiler superheater and before starting other parts of the separator. Boiler a number of safety door mounting vapor portion has strict requirements: the sum of emissions must be greater than the maximum continuous evaporation boiler; security door secondary vapor mounting portion, the total emissions must be greater than the reheater maximum design flow 100%. One of the properties is a very important energy saving boiler safety door, that is, from the seat pressure, also need to be adjusted and verified in accordance with the following general principles of addition of different manufacturers that have special provisions that drum and superheater outlet control safety door from reseating pressure for the working pressure 1.05 times, work safety gate from base pressure of 1.08 times the working pressure, reheater outlet safety gate from base pressure of 1.10 times the working pressure, the working safety gate from reseating pressure for the working pressure 1.04 times. Back seat pressure safety doors, should generally be from 4% to 7% of a seat pressure. From the seat pressure boiler using regular manufacturers of qualified products. Here to remind you overpressure test except this particular case, each security doors should be put into operation in the usual way, which is to protect the security doors are not subject to unnecessary damage, so that it can be possible to prevent energy saving boiler in each case overpressure situation occurs. We would also like security doors for regular inspection to ensure good facilities complete state. If you find that the door is not secure good sealing performance under operating pressure, we need to debug correction or replacement. Good quality security doors boiler use, excellent durability, as long as you use and maintenance in accordance with instructions, can protect the safe operation of energy-efficient boilers. These are the role of energy saving boiler safety door, you also have a lot of harvest it the same with small series? I hope this helps you make better use of energy saving boilers.

For atmospheric environmental quality issues, Harbin City, Heilongjiang Province, submitted a gratifying annual summary to the people within the city. By 2018, the number of days Hashi ambient air quality standard of 310 days, an increase of 40 days, since the implementation of our 2013 new environmental quality standards, the best of the year.

According to statistics, in 2018, out of a total of 1191 Harbin coal-fired boilers to provide strong support to reduce emissions of air pollutants.

Harbin coal-fired boiler was closed down following a major way, into the central heating (including wholesale) or clean heating pipe network replacement. According to the principle "and the appropriate and, should the electric power, the gas should be gas", the clean coal central heating pipe network coverage area, the boiler unit according to claim ownership, the priority region incorporated central heating pipe network; in concentration not covered by district heating network, in accordance with the wishes of the boiler unit property, taking clean renewable energy or alternative heating means, out of coal-fired boilers.

At the same time, various related businesses also improved stations, actively cooperate with the phase-out of coal-fired boilers.

2018 Hashi out of coal-fired boilers intensity of the strongest of the year, out of range built-up area expanded from 9 to zone outside built-up areas, out of a total of 1191 units. In District 9 built-up areas, on the basis of 10 tons of steam per hour out of coal-fired boilers to achieve "clear" on the further elimination of more than 10 tons of steam per hour to 99 coal-fired boilers; county (city) district built out of steam per hour 10 116 tons of coal-fired boiler units; elimination of financial support and utilities per hour 10 tons of steam coal-fired boilers 966 units in urban and outside built-up areas in the 9th district. "Achievements accumulated over the years, significantly reducing the use of coal, reduce emissions of pollutants." Director of Air and Noise Pollution Control at the Harbin environment bureau, Li Bin Tang said.

"In order to further solve the pollution problems of coal-fired, 2019, Harbin plans in urban areas, the county (city) built-up area basically eliminated 10 tons of steam coal-fired boilers and furnaces and tea, operating the stove, coal grain storage and drying equipment coal-fired facilities; urban built-up area basically eliminated 20 tons of steam coal-fired boilers, push 35 tons of steam coal-fired heating boilers out of the urban built-up area can not be a stable discharge standards; outside built-up areas out of 10 tons of steam can not be stable discharge standards of the following coal-fired boilers. "Li Bin Tang said.

Troubleshooting a Gas-Fired Hot Water Boiler

Modern boiler systems for home heating are hydronic systems, in which the boiler heats water for circulation throughout the house.They are closely related to steam boiler systems, but rather than circulating actual steam, hydronic systems have pipes carrying the hot water that radiates heat through either steel radiators or baseboard convectors (sometimes called "fin-tubes").
