The furnaces at Carleton Crematorium could be replaced under new plans, because the existing kit keeps breaking down.
Blackpool Council wants to install two temporary cremators for up to nine months while the upgrade is carried out, to avoid any major disruption.
In recent years, bereaved families wishing to hold services have faced delays of up to four weeks because of problems.
As well as plans to install two temporary cremators, the authority wants to extend the current cremation room to accommodate three replacement cremators.
Documents said: “The existing cremator installation at Carleton is no longer proving ‘fit for purpose’ as they are continually breaking down, falling into a position where they will be unsafe to continue using.
“This is affecting the overall operation of the crematorium and causing some delays to users.
“The council is therefore looking to have them replaced along with a new abatement installation to fully comply with current legislation.
“However, in the interim and to maintain the facilities continuity it has been decided to obtain two temporary cremators, which would be on site for between six and nine months.
“The acquisition of these two temporary cremator units, which sit inside adapted standard 20 foot steel containers, would keep the facility at Carleton fully functioning whilst the permanent replacement solution for the building is resolved.”
The procession route for funerals would be changed so mourners do not have to pass the temporary cremators.
The Gazette revealed in December 2013 how families were having to wait two weeks for services at Carleton, with delays increasing to four weeks by March 2014.
The crematorium, which has the capacity to carry out between 40 and 50 services a week, had been beset by problems in recent years.
The installation of a third cremator was halted in summer 2013 when the company fitting it, Crawford Europe, stopped trading.
Two cremators continued to operate, and the council secured a deal with ATI Environment UK Ltd to finish the third.
But then the second cremator at the facility had broken down.
Engineers then had to carry out additional work to comply with legislation on mercury emissions.
Carleton Crematorium opened in July 1935.
The building was created by Blackpool architect J.C. Robinson, who based his design on his own interpretation of the Mausoleum of Mausolus, a tomb built between 353 and 350 BC at what is now Bodrum, in Turkey, for Mausolus, a satrap in the Persian Empire, and his sister-wife.
The adjacent cemetery has more than 22,000 graves.
