Now on the market most of the fired boiler for package plants to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door.

The weather is getting colder and the demand for heating fired boiler for package plant products has increased. The packaged oil and gas boiler produced by ZBG can be used for heating in various areas such as greenhouses, farms, accommodation areas, office buildings, schools and other places. Also widely used in food factories, beverage plants, rubber plants, greenhouses, chemical plants, paper mills, building materials industry, garment and textile plants, washing plants and other industries.

Heilongjiang provincial government to respond positively to win the Battle of Blue Sky policy action plan issued by the Ministry of ecology and environmental protection, recently issued "on the issuance of Heilongjiang Province to win the Battle of the sky three-year action plan" (hereinafter referred to as "Plan").

"Plan" requirements, as of 2020, the province of sulfur dioxide, nitrogen oxide emissions are decreased year on year in 2015 to more than 11%; PM2.5 did not meet the concentration level and above cities fell year on year in 2015 to more than 15% , and above the level of urban air quality days ratio reaches 88%, and more heavily polluted year 2015 the number of days decreased the ratio of 15% or more.

"Plan" put forward 47 specific measures from nine aspects, namely: to adjust and optimize the industrial structure, promote the formation of green development; speed up the adjustment of energy structure, build clean energy systems; actively adjust the transport structure, the development of green transportation system; optimal adjustment of land structure, promote urban and rural non-point source pollution control; strengthening regional joint prevention and control, to effectively deal with heavy pollution weather; sound regulations and standards, improve environmental economic policies; for strengthening the infrastructure, strict environmental enforcement inspectors; clear responsibility for implementation of the parties, strict accountability assessment ; strengthen information disclosure, mobilize the whole society to participate.

"Plan" requirements, strictly control the total coal consumption.

1, in accordance with the focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, coal and oil to promote alternative energy by 2020, cities (prefectures) Coal accounts for the proportion of energy consumption fell by 1.5% compared with 2015.

2, bulk coal strengthening control, adjustment and optimization of high-pollution fuel combustion zone ban, the use of high-pollution fuel control, bulk coal alternative strengthening. Clean steadily heating, promoting the use of clean coal and clean energy.

3, to carry out comprehensive improvement of coal-fired boilers, to carry out level and above urban area 10 steam tons / hour coal-fired boilers and "clear" action. Improve energy efficiency, we continue to implement the dual-control operations total energy consumption and intensity.

4, accelerate the development of clean energy, and orderly development of wind power, biomass power generation and actively promote the construction of hydropower development focus on the promotion of river basins, and strengthen the development and utilization of geothermal energy exploration, increase renewable energy consumptive efforts.

Construction of gas steam fired boiler for package plant steam requirements for the construction of a gas boiler requirements, gas steam boiler installation for the construction of the boiler room have certain requirements, must comply with national requirements in the construction process. Gas and steam 1, the construction of a gas steam boiler room requirements 1) boiler room must comply with the "boiler energy saving technical supervision and management regulations" and "industrial boiler room design specifications" requirement. Gas steam 2) boiler room should have sufficient light and good ventilation, have the necessary antifreeze measures. And boiler room should stay away from schools, housing and densely populated areas. 3) the position should be close to the boiler room heating equipment, in order to reduce head losses and heat loss from the hot oil piping circulating pump. 2, furnace heat carrier device is arranged in claim 1) the sump should be lower than the lowest position of the heat carrier furnace and heat system 1 m, in order to put the net organic heat boilers and systems, sump and furnace heat carrier spacing less than 5 m or separated by a partition wall. It should be fitted with a sump exhaust pipe, which exhaust pipe diameter should be large and specifications than the inflation tube. 2) position of the expansion tank should be higher than the other devices and the piping system, the system must be higher than the maximum bottom level 1.5 m. It should not be installed directly above any one boiler, organic heat carrier to prevent overflow cause a fire. 3) the sump vent pipe, expansion tank, should be connected to the outdoor safety. Can not be mounted on the vent pipe to the valve, to ensure that the tank, the expansion tank to atmosphere to ensure atmospheric pressure operation. 4) the high volume of the expansion tank should be greater than 1.3 times and all the organic heat carrier furnace heat the entire heating systems is at the operating temperature is increased due to thermal expansion of volume. 5) low volume tank furnace heat carrier to be less than 1.2 times the total amount of organic heat. 6) hot oil circulation pump should be at least four weeks for 0.5 m space, and the inspection to ensure the installation routine, the need for maintenance.
