Industrial heating boilers

[ad_1]

The man­u­fac­ture of prod­ucts or oth­er options for com­mer­cial activ­i­ties involve the oper­a­tion of var­i­ous build­ings and struc­tures: work­shops, ware­hous­es, work­shops. The process of oper­a­tion of such objects implies, among oth­er things, main­tain­ing a com­fort­able tem­per­a­ture for work. Since such build­ings, as a rule, have a large area, spe­cial heat­ing equip­ment is used to heat the premis­es, in par­tic­u­lar, indus­tri­al boil­ers — hot water or steam. They are select­ed accord­ing to a pre-designed project.

Features of industrial heating equipment

To ensure the required tem­per­a­ture regime at indus­tri­al facil­i­ties, indi­vid­ual design is used, which takes into account the fol­low­ing char­ac­ter­is­tics of the struc­ture:

  • the pres­ence of ther­mal insu­la­tion of the walls and roof of the build­ing;
  • ceil­ing height and the vol­ume of the heat­ed room;
  • the type of equip­ment used that can affect the tem­per­a­ture regime (refrig­er­a­tion units, melt­ing or hard­en­ing fur­naces in met­al­lur­gi­cal plants);
  • the opti­mal type of fuel for the oper­a­tion of the boil­er (when choos­ing fuel, the effi­cien­cy and fault tol­er­ance of equip­ment are tak­en into account);
  • com­pli­ance with the require­ments of San­PiN 2019–2020;
  • the pres­ence of gates for trans­port and their equip­ment with ther­mal cur­tains.

Also, when devel­op­ing an indi­vid­ual heat­ing project, the pow­er of the heat­ing equip­ment is cal­cu­lat­ed. Indus­tri­al-type boil­ers include mod­els whose pow­er is more than 100 kW. When devel­op­ing a heat­ing project for such facil­i­ties, it is nec­es­sary to ensure com­pli­ance with SP 89.13330.2016 and SNiP 41–01-2003. These reg­u­la­to­ry legal acts define the require­ments for the design, con­struc­tion, repair and mod­ern­iza­tion of boil­er hous­es, as well as the require­ments for oper­a­tional safe­ty.

Distinctive features of industrial boilers

When choos­ing an indus­tri­al boil­er, you need to take into account a lot of nuances, since the equip­ment is clas­si­fied accord­ing to sev­er­al cri­te­ria.

By type of coolant

There are hot water and steam boil­ers. In the first case, water is used as a coolant, which cir­cu­lates through pipes under high, but not crit­i­cal pres­sure. In the sec­ond, the water is heat­ed to the state of steam, which cir­cu­lates through the pipes.

By type of energy carrier

Indus­tri­al boil­ers can use as fuel:

  • liq­uid fuel (solar, fuel oil, min­ing);
  • sol­id fuel (coal, fire­wood, pel­lets, wood chips);
  • elec­tric­i­ty (used in low-pow­er indus­tri­al boil­ers);
  • nat­ur­al gas.

Some­times bio­fu­els are also used, but this type of ener­gy car­ri­er is rel­e­vant only for low-pow­er boil­ers. These, accord­ing to GOST 20548–87, include instal­la­tions with a capac­i­ty of up to 100 kW.

According to the principle of heat transfer

Accord­ing to the method of trans­fer­ring heat from an ener­gy car­ri­er to a heat car­ri­er, boil­ers are fire-tube and water-tube. In the first case, heat exchange is car­ried out due to the fact that the pipe with hot com­bus­tion prod­ucts (with super­heat­ed steam) is in the coolant. In the sec­ond case, heat trans­fer occurs due to the fact that the coolant is pumped through pipes that are heat­ed from the burn­er.

The arti­cle was pre­pared with the sup­port of LLC “Promkot­lo­postavka” (world). The main direc­tion of work of Promkot­lo­postavka is the sup­ply of indus­tri­al boil­ers and oth­er heat­ing equip­ment from lead­ing Euro­pean man­u­fac­tur­ers.
